• Problems with the primary key of the query string

  Moving from asp to php, to work with David Power's book: The Essential Guide to Dreamweaver CS4 with CSS, AJAX, and PHP.  Recycling of my brain, so starting from scratch in the learning process.

  Everything was going perfectly until I tried to add the primary key of a record in a query string.  I compared my code with the example code for the book, and everything matches.  When previewing the page in my browser and hover over the link which must pass the main code on the next page, the query string does not appear correctly.  It shows user_id = but no figure shows, as it is supposed to.  www.webpage.com/update_user.php?user_id=

  Here is my code: (Please note, <>have been removed, as I was unable to find a way view the code in the correct way here (copy/paste was doesn't work do not, nor insert syntax))

  ? PHP {?}

  ? PHP echo $row_listUser ['family_name'];? PHP echo $row_listUser ["FirstName"];?

  ? PHP echo $row_listUser ['username'];?       ? PHP echo $row_listUser ["admin_priv"];?

  a href = "update_user.php? user_id =? php echo $row_listUser ['user_id'];?" "Edit / has

  a href = "delete_user.php? user_id =? php echo $row_listUser ['user_id'];?" ' Delete / has

  ? PHP} while ($row_listUser = mysql_fetch_assoc ($listUser));?

  Any ideas that could help me understand why this part does not in particular would be greatly appreciated.  Writing to the database worked perfectly, I see that there are numbers in the database as user_id, and it is defined as my primary key in the configuration database.  Such a simple process that is causing me headaches!

  Thank you

  You have the code to request a copy in your folder:

  $query_listUser = 'SELECT user_id, username, first_name, family_name, admin_priv from users ORDER BY family_name ASC';

  $listUser = mysql_query ($query_listUser, $connSCFDIR) or die (mysql_error ());

  $row_listUser = mysql_fetch_assoc ($listUser);

  $totalRows_listUser = mysql_num_rows ($listUser);

  $query_listUser = 'SELECT username, first_name, family_name, admin_priv from users ORDER BY family_name ASC';

  $listUser = mysql_query ($query_listUser, $connSCFDIR) or die (mysql_error ());

  $row_listUser = mysql_fetch_assoc ($listUser);

  The $listUser table will contain the results of the second query, which does not include the field user_id. delete the redundant code.

• implement the primary key on the field of forms

  Hello experts,
  
  I have a form with deptno single base table.
  dept_name and deptno. DEPTNO is a primary key in the database table.
  When I get the records, it prevents to insert the value that is duplicated in the deptno text box when I insert or update.
  
  the form I create a block with the base table, apply the primary key property of this Dept block. is Yes.
  then I put the key property primary deptno fields to yes.
  When I get duplicate records and then save, it prevents insertion but I want the following:
  
  I run the form, when I enter the first record, if it exists in the table can prevent to insert. also after the first record was inserted.
  If I insert to new deptno even into the next record, it must also prevent.
  
  Please help me.
  
  Thank you
  Yoann

  You have built your data forms to help block the "data block Wizard? If so, it already identified DEPTNO as the PK column. If it does not, or you have built your data manually block, you can open the palette property for the DEPTNO element and set the primary key property Yes. When this property is set on an element, the corresponding property of block, primary to apply key must also be set to yes. Please remember, however, that the Act of mark the DEPTNO as a PK does not 'Real time' checking for duplicates. Checking for duplicates occur when validation occurs. If you need a real-time duplicate check, you will need to write code to allow audits in double 'real time '.

  There are numrous examples in the forum to check duplicate in real-time as well as examples on the Internet. A search on Google for 'Check' the locker double shaped will give you lots of good examples.

• primary key on the form

  Hello
  
  I'm working on apex 4.0.2
  
  I have a table that has no explicit primary key in the creation of sql.
  ex:
  
  CREATE TABLE supplier
  (
  supplier_id numeric (10) not null,
  supplier_name varchar2 (50) not null,
  Contact_Name varchar2 (50)
  
  );
  
  
  
  But I know that the suplier_id column can play the role of the primary column.
  
  Is there a problem if I choose this column in the wizard as the main column?
  
  
  Best regards

• Create the primary key on the target

  Y at - it no IKM which would create the primary key on target after having read the instructions for the source?
  
  Thank you
  Dinesh.

  Hi Dinesh,

  You can customize a KM to create a primary key on the target
  The target table will be created with the mention of the primary key constraint in the data target store.

  Steps: -.

  Customiuse creating target step of the table and I create $ step table.

  for example: -.

  original train target table KM walk (IKM Oracle Simple incremental update): -.

  create table< %="snpRef.getTable" ("l",="" "a",="" "targ_name")="" %="">
  (
       <%=snpRef.getTargetColList("", "[COL_NAME]\t[DEST_CRE_DT] NULL", ",\n\t", "")%>
  )

  custom STAGE: -.

  create table< %="snpRef.getTable" ("l",="" "a",="" "targ_name")="" %="">
  (
       <%=snpRef.getTargetColList("", "[COL_NAME]\t[DEST_CRE_DT] NULL", ",\n\t", "")%>

  CONSTRAINT constraint_name PRIMARY KEY (< %="snpRef.getColList" ("",="" "[column]",="" ",",="" "",="" "pk")="" %="">)

• primary key for the table

  I have a Gr_order table that was settled long ago, and now he needs to be filled
  with some more search data.
  
  "Orderid" is a primary key for the table, but the question is how can I insert "orderid" in the insert statement in the procedure. I couldn't find any name sequence. There are 1230
  documents that must be inserted.
  

  Desc Gr_order
  Orderid  Number Primary key
  Desc     Varchar2

  INSERT INTO gr_order (orderid,desc)  
  VALUES (???, upper(each_pom.desc);

  Thank you
  Sandy

  You can find the code that inserts into the table and see if it uses the sequence ;-). A sequence is not 'attached' to a particular table - this is the insert statement to determine whether a sequence should be used.

  You can check if the table has a trigger - some developers like to emulate the behavior of MS - sql server by having a trigger on the table that selects in a sequence. If it has such a release, then you just do your insertions without specifying order_id. But if the table does not have such a release, then you cannot know if the table was originally filled using a sequence or not (unless you can find the instructions for inserting somewhere).

• How to get the primary key of the node selected in af:tree

  Hi all
  
  I use JDeveloper 11.1.1.5.0.
  
  I want to get the primary key of the node selected in the af:tree element. I wrote the code below in SelectionListener:
  

      public void drzewkoRwaSelectionListener(SelectionEvent evt) {
          RichTree tree = (RichTree)evt.getSource();
          TreeModel model = (TreeModel)tree.getValue();
          RowKeySet rowKeySet = evt.getAddedSet();
          Object key = rowKeySet.iterator().next();
          
          model.setRowKey(key);
     
          System.out.println(rowKeySet);
          System.out.println(rowKeySet.size());

  The result looks like this:

  [[oracle.jbo.Key[5 ], oracle.jbo.Key[6 ], oracle.jbo.Key[12 ],oracle.jbo.Key[14 ]]]]
  1

  I need the values of the last 2 nodes:
  1: oracle.jbo.Key [14]
  2: oracle.jbo.Key [12]
  
  How can I get?
  
  Kind regards
  Wojtek.

  Hello

  Try this code:

  {} public void drzewkoRwaSelectionListener (evt SelectionEvent)
  RichTree tree = (RichTree) evt.getSource ();
  Model TreeModel (TreeModel) = tree.getValue ();
  RowKeySet rowKeySet = evt.getAddedSet ();
  Key of the object = rowKeySet.iterator () .next ();

  model.setRowKey (key);

  System.out.println (rowKeySet);
  System.out.println (rowKeySet.Size ());

  Object [] keys = rowKeySet.toArray ();
  List (list) = keys [0];
  Keys = list.toArray ();
  * //from the table keys, you can get according to the value you want using as: [2], [3] key *.

• Returns the primary key of the new line (generated by the trigger) to an insert procedure

  Hello
  I have a table with a primary key (number), which increases with the trigger
  I use a procedure to insert data into this table
  How can I find the primary key of the row inserted to this procedure?

  When you make use of the insert:

  INSERT .... RETURNING key_column INTO variable;
  

  (where key_column is your key on the table column and variable is a variable to store the value of the same data type)

  to get the value in a variable.

• Problem by setting the primary key: relaxation Assigned primary key in the sequence.

  I have a table and a trigger for insert/update on the table. Trigger I get the game of the primary key of a sequence. I tested unit by inserting records in the table. It works very well. Kets primary key the next sequence number.
  
  I use this table as an entity in my adf application. The primary key attribute is set to "DBSequence". But when inserted I do not receive the following sequence for the primary key. Instead it is inserting the temporary number - ve that assigns the adf.
  
  I use JDeveloper 11 g.
  
  
  Can someone tell me what could be the problem?

  Your trigger should be something like:

  create or replace TRIGGER "SID_ASSIGN"
   before INSERT
   ON MY_TABLE
   FOR EACH ROW
  
  BEGIN
  
  if :new.SID is null or :new.SID < 0 then
     SELECT MASTER_SID_SEQUENCE.nextval into :new.SID from dual ;
  end if;
  END;
  

  You can refer to the guide of Dev of 11g for more details on this...

• 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:

• [SOLVED] Export Oracle SQL Data Modeler is missing a PRIMARY KEY on the DDL script

  I use data 4.1.888 maker to create an ER diagram and generate a DDL her script.

  The diagram contains more than 40 paintings, most of them have a primary key defined.

  For some reason any there is a table that has a primary key defined, but which is ignored when I export the model to a DDL script.

  It is the "wrong" key (even if it is checked that it is not found on the generated DDL script):

  

  This is where the key is set:

  

  And it is the preview of the DDL (Yes, primary key up there shows):

  

  This is what happens if I try to generate the DDL for just this (still not generated primary key) table:

  

  Has anyone had the same problem? Any ideas on how to solve it?

  There is no error in the log file, but when I run the generated DDL script there, and then I realized that I was doing something wrong:

  The table MEMBERS had a mandatory foreign key from another table, which in turn had a mandatory key against MEMBERS himself.

  So even if I could generate this primary key on members myself, and then run the the constraint definition that returned an error on the DDL script, I could not perform an insert operation on any of these two tables because of the constraint.

  I revised my design and realized relationships was not mandatory. I unchecked the mandatory box on the definition of the constraint and everything went well.

  I could reproduce the problem and the solution on a diagram with only two tables, so I'm sure that's it.

  Anyway, the Data Modeler is "a failed" silently in this kind of situation. It should be fairly obvious to an experienced designer that I was doing something wrong, but it is not so obvious when you deal with dozens of tables and all their relations and this is your first time using the Modeler.

  Thanks for your reply :-)

• Change of primary key on the Table clears the other columns

  Preliminary info/Installation
  JDeveloper 11 g 11.1.1.6.0
  We have a table (object view or entity) that has 8 columns. The primary key is composed of 4 1 columns.
  The table is displayed in a page fragment.
  2 of the 4 non-primary key columns are LOV.
  All the 8 columns are needed.
  The table is editable including 2 of primary key columns.
  
  Question
  Assume that the table displays the 3 lines. If we change a rank 1 non-primary key column and a primary key in row 2 column, everything works well when we are committed to the database
  If, however, we first change a primary key column, then a primary key on a different line column, then the column/row primary key that changed us first, gets annihilated and the other columns LOV on this same line. The 2 columns that are not LOV keep data as it should. We then get a validation error because the required data are not present. All this happens before we try all commit to the database. If debug us and look the iterator, it has the old data in this document, before and after any performance on the binding.
  If we look at and update the data via the App Module, everything works well. We have tried to update the view, etc. through valueChangeListener also with no luck.

  If you change the primary key value, it should not be the primary key.

  This is true in the design of database relational regardless of how access you the data. In addition, EO don't like if you change the primary key value.

  Have you considered adding a surrogate key (use a sequence) and make your PK course a unique key?

• Update primary key with waterfall

  Lets say I have 10 tables that have a foreign key defined, that everything points to a single table primary key.
  Now, I want to update the value of the primary key to another value, and I want all 10 tables to get this new value in their columns FK.
  Also, note also that some of these 10 tables can have this FK-value that is updated to PK-table.
  I can do this task with a good script?
  
  I would like to somehow in this way:

  Update PkTable set
  Pkcol=NewAvailableValue
  CASCADE;

  Right now I use the following approach:
  1. from table "user_constraints" find FK constraints binded to the primary change being key to find the list of tables.
  2 query each table if it has the PK value in their columns-FK, if has, then update the value allowed another PK-value.
  3. Update PK-value of primary key column of the table to the new value.
  4 validation.

  Maybe this will be useful: Tom Kyte: UPDATE CASCADE PACKAGE

• View of Materlized primary key and primary key in the master tables

  We use the Oracle 11 g 2 and I created a view on several paintings of master materlized. The paintings of masters all have the primary key, but I understand not all primary key columns in the query definition.
  According to Oracle manual e10592

  Specify WITH PRIMARY KEY to create a primary key materialized view. This is the default ....
  The master table must contain an enabled primary key constraint, and the defining query of the materialized view 
  must specify all of the primary key columns directly.

  My MV created OK and works. My question is what can be the impact on my MV? Could he hit to performance. It takes 40 minutes to the MV should be created and 5 minutes to refresh the one line insert in each table of mater. I would like to see it refresh in a few seconds.

  Retrieve the lines of the mview is purely a function of the number of lines and indexing on the mview himself. Mview refreshing at the time of the wall depends on the quality of the query used to refresh the mview. If you include the PKs of the source table in the mview matter or not, here. What matters is the execution of the refresh request path. Is it okay to indexation on the underlying tables to support the joints. Did you use mlog$ _s to allow a quick refresh - mlog$ _s are still usable for your mview. There are a number of possible causes for your problem and we do not have enough information to make an estimate of the problem.

  BTW, if the mview could refresh in a few seconds without mlog$ _s, probably unnecessary a mview.
