• Blockages with parent/child tables

  Guys,

  We have a parent-child of tables in our database with the DDL below:

  CREATE TABLE 'ACCOUNT '.

  (SELECT 'ACCOUNT_ID' VARCHAR2 (32 BYTE) NOT NULL,)

  X, Y, Z,...),

  'XPK_ACCOUNT' CONSTRAINT PRIMARY KEY ('ACCOUNT_ID');

  CREATE TABLE ACCOUNT_PARTITION ".

  (SELECT 'ACCOUNT_ID' VARCHAR2 (32 BYTE) ENABLE NOT NULL, "BALANCE" NUMBER (5.0) NOT NULL,)

  X, Y, Z,...),

  'XPK_ACCOUNT_PARTITION' CONSTRAINT PRIMARY KEY ('ID_COMPTE', 'BALANCE')

  KEY FOREIGN CONSTRAINT 'ACCOUNT_PARTITION_FK1' ('ACCOUNT_ID')

  SELECT THE 'ACCOUNT' ('ACCOUNT_ID') REFERENCES);

  "Lately, we cross " ""ORA-00060: Deadlock detected while you wait for resources ' errors while DELETING in the tables above. Please note that the tables of the child is not any clue except KP index.

  
  

  Could someone please suggest resolution for us to minimize the error of blocking?

  
  

  Respect,

  Bugs

  Imagine you remove account, Oracle must verify there is no record of the child in ACCOUNT_PARTITION, this is because as your FK is restrict the deletions (do not allow the removal if there are child records).  As ACCOUNT_PARTITION. Account_id is indexed so it will be an exclusive table lock to find this, locks the table.

  Another way of thinking is, imagine that you have performed the following query without and ACCOUNT_ID index:

  Select *.

  of ACCOUNT_PARTITION

  where ACCOUNT_ID =

  He SHOULD do a full table scan right?  Well well, even on a deletion of the parent. It attempts to identify lines for the purpose of blocking,

  As a general rule, it is always a good idea to index FKs.

• Update the data to uppercase in the parent/child tables

  Hi gurus!
  
  In production, we have a table product and that is in reference by many tables making parent child relationship. By mistake, we realized last month some products have been added to lowercase and now we have a request to update all these product codes uppercase so that existing code that use these tables have no impact. Appreciate if you can give an idea about how can I update the existing data in the table parent uppercase as well as child records?
  
  Concerning
  Sri

  Are the product code that you need to update what is stored in the tables of children? If Yes, then you must do it in several steps, something like:

  Identify the child tables

  SELECT table_name, constraint_name
  FROM user_constraints
  WHERE r_constraint_name = (SELECT constraint_name
                             FROM user_constraints
                             WHERE table_name = 'PRODUCT_TABLE' and
                                   constraint_type = 'P');
  

  Create new product of upper-case code in the product table:

  INSERT INTO product_table
  SELECT UPPER(product_code), other_columns
  FROM product_table
  WHERE product_code <> UPPER(product_code);
  

  Update the children tables for caps product codes

  UPDATE child1
  SET product_code = UPPER(product_code)
  WHERE product_code <> UPPER(product_code);
  

  Finally, remove the tiny product_table product codes

  DELETE FROM product_table
  WHERE product_code <> UPPER(product_code);

• Sum of a stand-alone parent-child table

  I have two tables - a 'key' table containing a parent-child relationship of multi-layer and a table 'amount' that contains the keys for the nodes in the key as well as table of numeric values (for example the amounts).
  I want a query that returns each line in the table of key as well as the sum of the amount amounts of the table for the set of nodes of this key (so the root node would be the sum of all values of quantity).
  
  Here's what I mean: I have two tables, the KEY and the AMOUNT
  
  KEY has two columns, keys, and parent_key; key and parent_key have a relationship CONNECT BY parent_key = prior key (with null for the root parent_key):

  KEY     PARENT_KEY
  0       null
  1       0
  2       0
  3       0
  1A      1
  2A      2
  2B      2
  3A      3
  3B      3
  3C      3
  1A1     1A
  1A2     1A
  2A1     2A
  2A2     2A
  2B1     2B
  3A1     3A
  3A2     3A
  3C1     3C
  3C2     3C

  AMOUNT a two columns, keys, and amount; key points to KEY.key and amount is a value for that particular key
  (Note that all key values are leaf nodes in the KEY table)

  KEY     AMOUNT
  1A1     1 
  1A2     2 
  2A1     3 
  2A2     4 
  2B1     5 
  3A1     6 
  3A2     7 
  3C1     8 
  3C2     9 

  What I want is a result that looks like this, where the amount of each key is the sum of the amounts of its possible keys sheet

  KEY     AMOUNT
  0       45
  1        3
  2       12
  3       30
  1A       3
  2A       7
  2B       5
  3A      13
  3B       0
  3C      17
  1A1      1
  1A2      2
  2A1      3
  2A2      4
  2B1      5
  3A1      6
  3A2      7
  3C1      8
  3C2      9

  For example, the value of the key 2 a, 7, is the sum of the values of 2 a 1 and a 2, 2; key value of 3 is the sum of 3 a 1, a 3, 2, 3, C 1 and 2 of 3.
  
  Is it possible to do this with a single query?
  The idea I came with is, do a select on the KEY with a "Key CONNECT_BY_PATH" column so that each line contains a string that contains the keys of all his ancestors and then do a join on AMOUNT with IN the CONNECT_BY_PATH amount.key column; However, with a large amount of data, it takes a little time. Is there a way faster / more obvious to achieve?

  OK you have almost everything you need. Outer join just your two tables, and then perform a hierarchical query, noting the key root of each tree. Then group the data set resulting:

  with t1 as (select '0' "KEY", '' parent_key from dual
    union all select '1', '0' from dual
    union all select '2', '0' from dual
    union all select '3', '0' from dual
    union all select '1A', '1' from dual
    union all select '2A', '2' from dual
    union all select '2B', '2' from dual
    union all select '3A', '3' from dual

    union all select '3A2', '3A' from dual
    union all select '3C1', '3C' from dual
    union all select '3C2', '3C' from dual
  ), t2 as (select '1A1' "KEY", 1 amount from dual
    union all select '1A2', 2 from dual
    union all select '2A1', 3 from dual
    union all select '2A2', 4 from dual
    union all select '2B1', 5 from dual
    union all select '3A1', 6 from dual
    union all select '3A2', 7 from dual
    union all select '3C1', 8 from dual
    union all select '3C2', 9 from dual
  ), t3 as (
    select t1.key, parent_key, amount
      from t1 left join t2 on t1.key = t2.key
  ), t4 as (
    select CONNECT_BY_ROOT key root_key
         , level lv
         , t3.*
      from t3
      connect by prior t3.key = parent_key

• Parent - child Table Insert Trigger

  Hello
  I need assistance with an Insert trigger. I want to insert field data 'Table A' "Table B" based on a PK and FK. Someone at - it examples of code?
  < code >
  Table A
  SEQ_NO - PK
  TO FIELD
  FIELD B
  C FIELD
  
  Table B
  FK_SEQ_NO
  FIELD B
  C FIELD
  < code >
  
  When the data is stored in the 'table A' I need fill out the 'FK_SEQ_NO', based on the saved value 'Table A' "SEQ_NO" as well as the values of FIELD B and C FIELD recorded in Table B.
  Any help is really appreciated, thank you.

  Hi Charles,

  It depends exactly how you created your trigger.

  In my trigger I fill WORK_PACKAGE_ID (PK) in the parent table using rmdb_work_packages_seq. NEXTVAL. The insert statement then uses: NEW. WORK_PACKAGE_ID to fill the coumn FK in table child.

  You can also use ITEM_ID_SEQ. CURRVAL who will repeat the last number that was created, and I suppose that you use to fill A table.

  Hope that helps,
  Martin

• Parent - child Tables (query to sum up)

  Hello people:

  Hope you're all well today.  Here is my sample data:

  WITH the fleet (fl_id, veh_id)

  SELECT 105, "T22" OF THE double

  ),

  fleet_keys (id_pk, fl_id_fk, key_number) AS

  )

  SELECT fl.veh_id, flk.key_number FROM floating fl

  LEFT JOIN fleet_keys ON fl.fl_id = flk.fl_id_fk flk

  This simple query with a left join on the primary key to foreign key produces the following data set:

  	ADB185
  	ADB186
  	ADB187
  T22
  	BCB205
  	BCB206
  	BCB207

  Is there an easy way to do this?  Thanks for your help.

• Why Developer SQL displays arrows (relations) between parent and child tables in my entity relationship diagram?

  Hello

  
  

  Oracle version:                     Oracle Database 11 g Release 11.1.0.7.0 - 64 bit Production

  The version of SQL Developer: 4.0.2.15 - 15.21 build

  I have a question about drawing diagram, entity-relationship with SQL Developer & I would be grateful if you could kindly give me a helping hand.

  I would like to draw an entity-relationship diagram in order to better visualize the relationship between multiple tables. After a google search, I found the following interesting article indicating the procedure to be followed:

  http://www.Oracle.com/technetwork/issue-archive/2014/14-may/o34sqldev-2193423.html

  (What I need and I'm trying to produce is Figure 4 in the article above)

  I made exactly as stated in the article & apparently everything has worked well enough, in other words, I had several UML as rectangles showing columns of tables, their data types, primary and
  foreign key and the arrows indicating the link between each parent/child table.

  Later, I tried to do the same thing on a different oracle instance and a different database by using the same procedure. Yet, something strange happened this time. Developer SQL printed on-screen tables, once again,.
  inside the rectangles with types, keys,... but, there was no arrow showing the link between the tables, I just saw on the grid the selected tables but without any association/relationship shown (as a symbol of an arrow)
  between them.

  I repeated the procedure on another instance of development, with a few test tables that I created with primary and foreign keys just to make sure I had followed the procedure correctly. Once again

  the test was successful, but when I repeated the test on another instance, the same problem persisted, in other words, no arrow (relationship) between tables.

  Any idea?

  This could be due to a lack of privilege on the instance? If Yes, what should be granted in what about roles?

  Thanks in advance

  I think that what you see is that not all databases have foreign keys - applications hard-coding relationships vs let the database to handle this.

  Connect to this instance different oracle and browse the tables affected - have FK constraints defined on them?

• How can I make sure that changes in a primary key (in the parent table) would also appear directly in the FOREIGN KEY in the child table?

  Forgive my question. I am very new to Oracle.

  How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?

  Is that not all the primary key and FOREIGN KEY on?

  My paintings:

  I created 2 tables and connect to apply in the data base referential integrity, as I learned.

  CREATE TABLE - parent provider

  (the numeric (10) of supplier_id not null,)

  supplier_name varchar2 (50) not null,

  Contact_Name varchar2 (50).

  CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)

  );

  CREATE TABLE - child products

  (the numeric (10) of product_id not null,)

  supplier_id numeric (10) not null,

  CONSTRAINT fk_supplier

  FOREIGN KEY (supplier_id)

  REFERENCES beg (supplier_id)

  );

  I inserted the following text:

  INSERT INTO provider

  (supplier_id, supplier_name, contact_name)

  VALUES

  (5000, 'Apple', 'first name');

  I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.

  How to get there?

  Thanks in advance!

  Hello

  What is a foreign key in Oracle?

  A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.

  Ok!??

  What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?

  A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.

  If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

• BULL, INSERTION IN THE PARENT TABLE AND THE CHILD TABLE

  Hi all
  
  We use bulk insert to improve performance. How to use this concept when I insert the records parent in table parent and child?
  
  example... I have a procedure that accepts the array of student objects
  
  each student object is defined as *(student name, student age, course_object_array) *.
  
  the 3rd element course_object_array is defined as *(coursename,course fee,facultyname) *.
  
  a student can be associated with several courses
  
  Now, I have to insert the data into two tables namely students (studentname, studentage and student_number)
  courses (course_id, coursename, fees, facultlyname, student_number)
  
  I use sequences to fill the columns student_number and course_id.
  
  If I use bulk insert, and insert all the records in the parent table how do I the association for each record of a child. How will I know what child folder must be associated with which of the parents?

  Hi thanks for the reply Solomon.

  I actually know about the bulk collect and for all...

  Have you read that FOR ALL with in fact BULK COLLECT? It will allow you to bulk insert via for ALL with VOTING student_numbers attributed to each student placed in a collection. Then, you will use this collection collection of course list to fill the RACE table.

  Hi all the Scripting Guys,.

  I created a table using rules xml with 3 numbers of the cells where first cell contains some data and so on, but following the cell first line may of does contain all the data so in that cell of second data line moved to the first cell and thired data line moved to the second cell that is very worried about me since the second cell in each row must be in the second cell only.

  Oops, I apologize. I misunderstood the requirement.

  And this example shows us why the rules XML in InDesign is not the most practical approach...

  Beforehand, for each , we went to the top parent and found a and copied in.

  But we did only want to do this for the first .

  But convert us all the , , and

  the knots in the table cells later, we therefore need to insert a space reserved for this place to avoid having a problem. (If not, we could hardcode the number of the column for and the

  lymph and prepopulate the nodes of the table...).

  So I'll offer several changes to the fragmentary manuscript, thus you can intergrate them and learn what is happening:

  First of all, let's change these helper functions to return a null value in the event that they do not find a child node, rather than return the node parent. This means that it is easier now to test their return values in case of not finding something, that is a case that we know today:

  // Handy subtree functions
  function firstChildTag(node, tag) {
      var i, e = node.xmlElements;
  
      for (i=0; i=0; i--) {
          if (e[i].markupTag === tag) {
              return e[i];
          }
      }
      return null;
  }
  

  Then, we must be able to copy nodes in particular places. Before we used it copied copyFromToChild() who always has nodes in the context node. But we need to be more general, copy the tags. We'll create a version that allows us to specify the destination:

  // Apply from() to the context node to get
  // a source node. Apply to() to the
  // context node to get a destination node.
  // Copy the source node in the specified
  // location (how) to the destination node.
  var copyFromTo = makeRule("copyFromTo",
  function (element, ruleProcessor, from, how, to) {
      var copy;
  
      // __processChildren(ruleProcessor);
      copy = from(element).duplicate();
      copy.move(how, to(element));
      __skipChildren(ruleProcessor);
      return XMLmm.stopProcessing;
  });
  

  It must also be able to add an empty tag in the other nodes in . Maybe in hindsight I should have just made a new node outside the subtree us work and then copied that every time with the function copyFromTo() above. But instead, I expanded addNode() (which is currently used to create rows in the table) to not take a fixed destination, but rather a function that returns a destination, so that the destination can then be compared to the context node:

  // Create a new node at parent. Doesn't do
  // anything with the XPath context node.
  var addNode = makeRule("addNode",
  function(element, ruleProcessor, where, tag) {
      var parent = where(element);
  
      if (parent) {
          parent.xmlElements.add(tag);
      }
      return XMLmm.continueProcessing;
  });
  

  Now, we can replace the first transformation rule (which allows to copy into all the s) article by another who works on each and copy to the beginning of the first brother according to . Note that the XPath specifier is "//section/section-head" rather than "/ / section" because we do not want to operate on the copy that we have inside the tree. Otherwise, we get double nodes.

  // For each , that it is a direct child of a 
  ,
  // copy it inside the first  child.
  // Next, move each 
   node to the end of the ,
  // placing it after the  node.
  __processRuleSet(root, [
      copyFromTo(
          "//section/section-head",
           function(n) { return n; },
           LocationOptions.AT_BEGINNING,
           function(n) {
                  return firstChildTag(n.parent,tags["para"]);
              }),
      moveFromTo(
          "//para",
          function(n) { return firstChildTag(n, tags.article); },
          LocationOptions.AT_END,
          // This is more general than we need to be; we're moving
          // to "the end", but the end of WHAT? It need not be the
          // , it could be some other node.
          function(n) { return n; })
  );
  

  Now, we need to deal with the other s that have no in them. I'm not proud of it, we could probably do better. And would certainly be easier without XML rules. Or if we had the position() XPath function:

  // This is kind of gross.
  // For each , if it does not contain a ,
  // add a  to it. This adds it to the *end*
  // of the 's chilld list.
  __processRuleSet(root, [
        addNode("//para", function(n) {
            if (!firstChildTag(n, tags["section-head"])) {
               return n;
           } else {
               return null;
           }
        }, tags["section-head"]),
        moveFromTo(
            "//para",
            function(n) { return firstChildTag(n, tags["section-head"]); },
            LocationOptions.AT_BEGINNING,
            function(n) { return n; })]);
  

  Oh, and finally, we have changed the way that worked addNode(), so adjust the another call to addNode for a function instead of an explicit node:

  So in the latest set of rules, change to:

  addNode("//para", function() { return table; }, tags.tr),
  

  It works for you?

• Create a parent child

  in collaboration with JDev12.1.2.

  I have a view object that is based on a query. I then another editable view object from an entity. 2 then have a link with a field view id. The VO being the parent and the VO entity based application shall name a child and having a 0.1 - 1 ratio. How can I display a table with each row in the table parent with a child, even if the child does not yet exist. I don't want to have to go and click a button create/insert for each record in the table.

  I was finally able to get it figured out. I had to get rid of my request based on VO and create 2 entity with an association to the entity objects. I then created a VO using the 2 entities and the Association. Then when I created a table of the VO it displays blank fields for the (child table) that you could call it. Then to commit it inserted records children if I entered what anyone in the fields. I had a problem with them not fixing is not the ID that connected the 2 entities, but I managed to fix that in the file VORowImpl of java.

• Records in the Child Table to return DBAT connector deletion and addition

  I'm trying to add a record of the child to a resource DBAT (11.1.1.5). The structure of the Table is set up like this:

  OIM_USR

  Usr_key	First name	Last_name

  OIM_ROLE

  USR_KEY	ROLE_KEY

  Where OIM_USR is the parent, and OIM_ROLE is the child that can store multiple values per user.  The problem arises when there is already an existing value in the child table. Consider the following example for instance

  OIM_USR

  Usr_key	First name	Last_name
  45	John	DOE

  OIM_ROLE

  USR_KEY	ROLE_KEY
  45	2454
  45	4453

  If I add another line to the role of the identity UI table Edit tab added resource role, but IOM is remove the previous two lines and then adding them back. We know that it is because the source OIM_ROLE table contains a timestamp of creation triggered update time when a row is added. If I add a line to OIM_ROW then all three are getting updates for a reason any. We can also see the history of resource shows three updates. Inserting a record of the child should not call the process of update tasks. I've attached a screenshot of the history of the resource.

  In addition, I upped the DBAT Connector logs and he showed a trace of remove:

  DELETE FROM OIM_ROLES WHERE OIM_ROLES. USR_KEY =?

  Why he deletes all children lines before an insertion?

  I think you use OOTB DBAT connector without modification. I think that's how its design to add/change/delete files. For child process also updated form, we follow the same approach.

  Are you facing any functional problem in connector DBAT to reach your use cases?

• Get the parent-child hierarchy of column delimited

  I've been on this forum once before, and someone helped me, so I hope I can get help again!

  4-15-5987');

  Thus, the hierarchy is divided on the hyphen. first parent being 4245, then the next value is-4 (including the hyphen) and what follows is - 1, for example

  CREATE TABLE REGEXTEST
    ( ITEM VARCHAR(20)); 
  
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-1');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-10');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-11');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-12');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-13');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-14');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15-59A7');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15-59D7');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15-59F7');
    INSERT INTO REGEXTEST (ITEM) VALUES ('4245-
  
  

  I have to be able to bind-1, -4, 4245. Perhaps the simplest is to build a new table with a primary key where it is assigned the id of the parent to the child.
  I just can't understand how to divide the individual elements and maintain the hierarchy. As previously mentioned, someone helped me with another part of the problem before where I needed to maintain the entire path of each child with the following query:

  select  nvl(prior item,item) parent,
          nvl2(prior item,item,null) child
    from  REGEXTEST
    connect by substr(item,1,instr(item,'-',-1) - 1) = prior item
    order by child,parent
  
  

  Now, if I could extrapolate that into a new table:

  CREATE TABLE FileHierarchy
  (ItemID INT NOT NULL PRIMARY KEY,
  ItemName varchar(50) NOT NULL,
  ParentID INT NULL);
  
  

  ItemName is the 4245 or - 4 or - 1 (only) - Yes, including the hyphen.

  The ID of the parent-1 would be the ID-4, etc...

  Thank you very much in advance!

• Drawbacks to the use of the child tables

  Hi, in Oracle NoSQL-GSG - Tables.pdf page 22: "Note that there is no downside to using children tables [instead of folders] even for the trivial cases."
  But currently, there are some disadvantages disadvantages, as illustrated in this simplified example:

  create a table - name personal
  Add-field - type STRING-identification
  Add-field - type STRING-familyName name
  Add-check-domain - name postalAddress
  Add-field - type STRING-city name
  Add-field - type STRING-name street
  output
  Add-check-domain - name invoiceAddress
  Add-field - type STRING-city name
  Add-field - type STRING-name street
  output
  primary key - id field
  output
  Plan add a table-name Personal-wait

  # In addition, we define the child table having a similar structure to show the differences:
  create a table - name Personal.Address
  Add-field - type STRING-name of the type of
  primary key - field type
  Add-field - type STRING-city name
  Add-field - type STRING-name street
  output
  add name Personal.Address table map - wait

  connect store - name kvstore

  
  «"set table - name personal - json ' {\"id\":\"1\', \"familyName\":\"Wu\'", \"postalAddress\ ': {\"town\":\"Rio\", \"street\":\"MyWay\ ""} ', \"Address\ ': {\"type\":\"delivery\', \"town\":\"Rio\'", \"street\":\"MyWay\"}}»
  # Please, you could allow "instead of"in the syntax of CLI to avoid ugly \"hiding?"

  get table - personal name - enough
  # Result is:
  {
  « id » : « 1 »,
  "familyName": "Wu."
  'postalAddress': {}
  "City": "Rio."
  "the street": "MyWay".
  },
  'invoiceAddress': null
  }
  # Address data (from child table) are not displayed (but it's a feature!)

  
  get table - name Personal.Address - enough
  0 rows returned
  # address data was not stored (and no error message was displayed in the command put above).

  "set table - name Personal.Address - json' {\"id\":\"1\", \"type\":\"delivery\"", \"town\":\"Rio\" ", \"street\":\"MyWay\ "}".
  get table - name Personal.Address - enough
  {
  « id » : « 1 »,
  "type':"delivery. "
  "City": "Rio."
  "the street": "MyWay".
  }
  # Good, it is stored, but not 'nested' correctly:

  
  get table - name personal - child Personal.Address - enough

  # This gives the person and her child in a sequence:
  {
  « id » : « 1 »,
  "familyName": "Wu."
  'postalAddress': {}
  "City": "Rio."
  "the street": "MyWay".
  },
  'invoiceAddress': null
  }
  {
  « id » : « 1 »,
  "type':"delivery. "
  "City": "Rio."
  "the street": "MyWay".
  }

  Kids tables are normal tables that have a name containing a point and that inherit the keys to their anchestors. They have disadvantages compared to the record types.

  At least the input/output JSON data is not as expected.

  Hello

  Child tables exist for two main reasons.

  1. They allow the related data modeling in independent lines, as I mentioned earlier.  In a relational system do you this with another table and a join to get information at the same time.
  2. Data in table, they allow access to the mother and child in an efficient and transactional data.  That you don't get modeling them as independent and make a join.  This is probably the point you've been away.

  Popping up a level of abstraction, Oracle DB NoSQL is a sharded system, designed to provide horizontal scaling with consistent performance.  It does this by placing recordings of the pieces separated according to the brightness of the line key.  All lines with the same brightness key are stored in the physical basis and are therefore available in a transactional manner.

  In a first level table (i.e. one without a parent) the brightness key is either explicitly set or it is precisely its primary key.  The brightness of a child table key is always key brilliance of its parent.  This means that if you have a table person with a primary key of '1' then all its child table lines who share this part of their primary key (e.g. <"1", "work_address"="">, <"1", "home_address"="">, etc.) are accessible to all, in the same transaction - that works for multiGet and updates, which can be done with lists of TableOperation.

  You're trying things with the CLI, which works, but is not the richest way to access the system, and is of course confusing sometimes.

  -Child flag you saw in the CLI is not there to specify the relationship between the table of the child, but rather to indicate that you want to get records from this table as well.  For example, if you have a person parent table and child table address and that you only want the parent lines that you do:

  get table - name person

  If you want to get the lines both person and address you

  get table - name person-child address (or Person.Address, I do not remember offhand)

  To do a specific identity, you do

  "get table - name person - child address - json ' {'id': '1'}"

  Is - this make more sense?

  Kind regards

  George
