Create a query to compare the values in the same table

• Comparing the same tables of two schemas

  I had already posted a similair on this thread. So, I thought I would start a new thread on this to avoid confusion
  
  I want to generate a report that shows the difference in the data type of the columns in the same table in two different patterns.
  
  The query using LESS shows the difference below.
  
  

  create table SCOTT.mytab1 (empid number);
  create table HR.mytab1 (empid varchar2(34));
  
  
  SELECT   table_name, column_name, OWNER schema, data_type
  FROM     dba_tab_cols where owner = 'SCOTT'
  AND TABLE_NAME = 'MYTAB1'
  MINUS
  SELECT   table_name, column_name, OWNER schema, data_type
  FROM     dba_tab_cols where owner = 'HR'
  AND TABLE_NAME = 'MYTAB1'
  
  Result:
  TABLE_NAME      COLUMN_NAME     SCHEMA     DATA_TYPE
  --------------- --------------- ---------- ------------
  MYTAB1          EMPID           SCOTT      NUMBER

  But, since it is a report, I want to see the form of results the two schemas that has column of different data types with the same names of table
  
  Expected results:

  TABLE_NAME      COLUMN_NAME     SCHEMA     DATA_TYPE
  --------------- --------------- ---------- ------------
  MYTAB1          EMPID           SCOTT      NUMBER
  MYTAB1          EMPID           HR         VARCHAR2

  Anyway I could do this?

  Why not get a single line with two types of data:

  select a.table_name, a.column_name, a.data_type schema1_type, b.data_type schema2_type
  from all_tab_columns a, all_tab_columns b
  where a.owner = 'SCOTT'
  and b.owner = 'HR'
  and a.table_name=b.table_name
  and a.column_name=b.column_name
  and a.data_type!=b.data_type;
  

  This extracted single query columns present on the two schemas but with different data types. These columns only on one of the two schemas are not extracted.

• How to optimize the update statement so that the query is reading the same table?

  Hi all

  I have a process with the following UPDATE statement:

  Sales_val update

  SET ship_date =)
  Select max (hist.ship_date)

  FROM sales_hist hist

  WHERE hist. X_ID = A.X_ID

  AND hist. X_VAL = A.X_VAL)

  ) WHERE EXISTS (select * from sales_hist hist where )

  WHERE hist. X_ID = A.X_ID

  AND hist. X_VAL = A.X_VAL

  )

  sales_val - 50 lines mln (unique index)

  sales_hist - 20 mln ranks (unique index)

  I met many problems with waits and locks - how to optimize to avoid locks using the parameters of tables or changes of the declaration? or maybe is there another way to do optimization ?

  Kind regards

  Thank you for that. Collect in bulk Unfortunatelly + FORALL does not work with the types in 10g - solution is to use the FOR loop and is not as effective as FORALL in many cases. I do still some tests to solve this problem - I'll put you once it's done.

  EDIT: hash partitioning + fusion - 3-5 minutes (time), so for now it's the solution to the problem. Thank you all for the great discussion!

• How to do a subquery in the same table?

  I'm trying to figure out how to query inside a query...?
  
  Here is my table:
  
  NAME ID (PK)
  
  My problem is when someone creates a new line in this table, the system creates other lines associated in the same table, but it fits the ID of the line of "parent" in the name of the new colums.
  
  For example:
  
  1001 BOB_ADDRESS
  1002 FRED_ADDRESS
  1003 NEW_ROW_1001_BOB_ADDRESS
  1004 NEW_ROW1_1001_BOB_ADDRESS
  1005 NEW_ROW_1002_FRED_ADDRESS
  1006 NEW_ROW1_1002_FRED_ADDRESS
  
  
  What I want is a query that would work to something like:
  
  SELECT ID, NAME
  FROM TABLENAME,
  BY NAME;
  
  But this query finds all rows of the child >
  
  For example:
  
  ID NAME
  ---- ---------------------------------------
  1001 BOB_ADDRESS
  1003 NEW_ROW_1001_BOB_ADDRESS
  1004 NEW_ROW1_1001_BOB_ADDRESS
  1002 FRED_ADDRESS
  1005 NEW_ROW_1002_FRED_ADDRESS
  1006 NEW_ROW1_1002_FRED_ADDRESS
  1010 JOE_ADDRESS
  1100 NEW_ROW_1010_JOE_ADDRESS
  1117 NEW_ROW1_1010_JOE_ADDRESS
  
  Any thoughts?
  
  Thank you

• comparing string values in the same table

  I have a table with ID (14 digit string values) starting with "A". Ex: A21849B1020792. There may be a different ID with the same substring 'B1020792' in the same table, example: A12349B1020792. If this happens, the ID of the last creation date of must be returned in the result. In other words, comparison is done on the same table. "In the example provided, say A12349B1020792 has the date of 1 January 2015 'and A21849B1020792 has date February 1, 2015", since A21849B1020792 has the most recent date, the result must contain only A21849B1020792.

If I added a.id column in the select clause and the group by clause, the query includes both by substr (a.id, 7) and a.id and as a result, the query returns four lines as below:

  substr (a.id, 7) select sc, max (a.create_date) cd1, a.id ID

  of table a, table b

  where a.id! = b.id

  and substr (a.id, 7) = substr (b.id, 7)

  If it makes sense to treat the first 6 characters of the ID separately from the rest of the id in this problem, maybe it makes sense to store those two parts of the id in two different columns.  Relational databases work best when each column of each row contains 1 single piece of data (at most).  It is so fundamental to the design of table that he called the first normal form.

  Given that the two parts are stored in column 1, so you can something like this Request Top - N:

  WITH got_r_num AS

  (

  SELECT r.id

  r.create_date AS cd1

  , RANK () OVER (PARTITION OF SUBSTR (r.id, 7))

  ORDER BY r.create_date DESC

  ) AS r_num

  FROM table_x g - g for data values

  JOIN table_x r - r for related values

  ON SUBSTR (r.id, 7) = SUBSTR (g.id, 7)

  WHERE g.id IN ('A12349B1020792'

  , "A21849B1020792".

  , "A12345B1234567".

  , "A43567B1234567".

  )

  - AND g.id LIKE 'A %' - if necessary.   The above condition ensures already g.id start with "A".

  AND r.id LIKE 'a % '.

  )

  SELECT id, create_date

  OF got_r_num

  WHERE r_num = 1

  ;

  If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test this.

• place a select query calculation in a different column in the same table

  How can I put my calculation result in a column named within the same table?

  I have a table called: dgpercentagedatachart

  I use the columns of this dgpercentagedatachart: totalcecrating divided by lowestfeederrating times 100 to get the percentage

  In the query, I gave the result the Alias of the cal

  What I want is to put this result in my application or my calculation (in percentage) in my column "percent" on my table of dgpercentagedatachart vacuum.

  How can I configure this syntax?

  This is the select query, I came with:

  Select dgpercentagedatachart.totalcecrating, dgpercentagedatachart.lowestfeederrating,.

  100.00*dgpercentagedatachart.totalcecrating/dgpercentagedatachart.lowestfeederrating as cal

  To change an existing column in a table, you can use the UPDATE or MERGE, instructions like this:

  UPDATE dgpercentagedatachart

  Percentage of VALUE = 100,00 * totalcecrating

  / lowestfeederrating

  ;

  Noramlly, tables is not redundant columns like this.  If percent can always be calculated from other columns, then it is probably better to calculate at run time and store it in the database, where you will have to be updated each time the columns it depends on change.  You can use a view to avoid having to encode them the calculation.

  If you really don't want a column that can be calculated in the same lines other columns, then use a virtual column (if you use Oracle 11 or higher).

  I hope that answers your question.

  If this isn't the case, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

  If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.

  Explain, using specific examples, how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Updated with the values in the same table, for other records corresponding to conditions

  Hi Experts,

  Sorry do not provide the structure of the table (it is a simple structure)

  I have a requirement where I need to update the columns of a table based on the same table with some match empid and date values. If the date and empid match so I have these values to any other folder and update of one who is not having details of Office . I need the Update query

  Before the update my array of values is as below

  Sort_num Emp_id Bureau start_date

  1 101 AUS 01/01/2013
  2 101 01/01/2013
  3 101 15/01/2013

  8 104 10/01/2013
  9 104 01/01/2013

  After update my table should be as below

  Sort_num Emp_id Bureau start_date

  Thanks in advance

  I don't have the time to create the table with the data, but basically, you should be able to code the following text

  update one table

  Office set = (select desktop in table b where b.emp_id = a.emp_id)

  and b.start_date = a.start_date

  and b.office is not null

  )

  where is ([as well as overall query])

  and a.office is null

  In my opinion, who will do the trick.

• update to column values (false) in a copy of the same table with the correct values

  Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.
  
  My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:
  
  
  Update mnt.workorders
  Set approvalstat = (select b.approvalstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  where exists (select *)
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  
  It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.
  
  Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:
  
  Update (select a.comappstat, b.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi - this is a PK column
  and a.comappstat! = b.comappstat)
  Set b.comappstat = a.comappstat
  
  Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:
  
  Update mnt.workorders_copy
  Set comappstat = (select distinct)
  a.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi
  and a.comappstat! = b.comappstat)
  where a.comappstat! = b.comappstat
  and a.workordersoi = b.workordersoi
  
  The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :
  
  ERROR on line 8:
  ORA-00904: "B". "" WORKORDERSOI ": invalid identifier
  
  First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)
  
  Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?
  
  I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.
  
  Thank you

  Hello

  First of all, after post 79, you need to know how to format your code.

  Your last request reads as follows:

  UPDATE
    mnt.workorders_copy
  SET
    comappstat =
    (
      SELECT DISTINCT
        a.comappstat
      FROM
        mnt.workorders a
      , mnt.workorders_copy b
      WHERE
        a.workordersoi    = b.workordersoi
        AND a.comappstat != b.comappstat
    )
  WHERE
    a.comappstat      != b.comappstat
    AND a.workordersoi = b.workordersoi
  

  This will not work for several reasons:
  The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
  There is no link between the mnt.workorders_copy and the the update and the request of void.

  If you do this you should have something like this:

  UPDATE
    mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
  SET
    A.comappstat =
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  WHERE
    EXISTS
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  

  Speed is not so good that you run the query to sub for each row in mnt.workorders
  Note it is condition in where. You need other wise, you will update the unchanged to null values.

  I wouold do it like this:

  UPDATE
    (
      SELECT
        A.workordersoi
        ,A.comappstat
        ,B.comappstat           comappstat_OLD
  
      FROM
        mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
        ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
  
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    ) C
  
  SET
    C.comappstat = comappstat_OLD
  ;
  

  This way you can test the subquery first and know exectly what will be updated.
  This was not a sub query that is executed for each line preformance should be better.

  Kind regards

• Problem in creating several attributes XML with the same name of the attribute

  I am trying without success trying to create several attributes XML with the same name, as shown here in a Microsoft example configuration file:

  
  
    
       
       
       
    
  

  I'm calling the NewDocument GetRootElement functions and then "newelement" (appSetting), "newelement" (add)

  Then I call AddAttribute with add, key & Key0, then with add, value & 0.  This seems to work fine but when I try to add the second pair of key & Key1 and value attributes & 1 for item "Add" replaces ""and I find myself with"" only.

  I do something wrong or CVI is not able to create an XML of this type?

  Thank you

  Here's how you do it. I show not to keep things simple error checking.

  #include

  public static void CreateAddElement (mother of CVIXMLElement, const char * key, const char * value)
  {
  Add the CVIXMLElement;
  CVIXMLNewElement (parent, -1, 'Add', &add);)
  CVIXMLAddAttribute (add, "touch", key);
  CVIXMLAddAttribute (add, "value", value);
  CVIXMLDiscardElement (add);
  }

  void main (void)

• If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?

  Mr President

  If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?

  My two fields are FLOW AND DR_NAME

  FLOW = ACCT_ID

  DR_NAME = ACCT_NAME

  I created with success of LOV for these fields.

  First LOV gives acct_id in the debit field and second LOV gives the value of acct_name to dr_name.

  How can I report these lov, it's that when I change my acct_id then acct_name also change

  I have these two tables

  CREATE TABLE "NOM"  (
    "ACCT_ID" VARCHAR2(7) NOT NULL ENABLE, 
    "ACCT_NAME" VARCHAR2(50) NOT NULL ENABLE, 
    "O_BAL" NUMBER(13,2),
    CONSTRAINT NOM_PK PRIMARY KEY ("ACCT_ID")ENABLE
     
     );
  CREATE TABLE "VOUCHERDET" (
    "V_ID" VARCHAR2(9) NOT NULL ENABLE,
    "LINEITEM" NUMBER ,
    "DEBIT" VARCHAR2(7) , 
    "DR_NAME" VARCHAR2(50), 
    "CREDIT" VARCHAR2(7) , 
    "CR_NAME" VARCHAR2(50), 
    "PARTICULARS" VARCHAR2(100), 
    "AMOUNT" NUMBER(21,2),

• How to create fields in double on the same page?

  Hello

  I use Adobe Acrobat Pro and I just downloaded DC, in the hope that it works better.  I am creating a field duplicate on the same page.  When the drop-down list option is selected in one place, I would for the same answer to appear in another location, on the same page. I tried to copy/paste and "Create several Copies", but whenever a copy is created, Adobe assigns a unique number to distinguish it from the original.  From what I read in the help forums, the name of the fields must match. I tried to rename the fields, but adobe won't let not two fields have the same name.  The section forums and help also claim that when the copy of a field, it automatically gets the same name as the original, which does not happen in my case.

  What I am doing wrong?

  Thank you!

  The 'number 1' you see is just a way to indicate that it is a copy. They have fields

  in fact having the same name and their values must be the same (if it's a)

  drop-down menu, if you will not have to leave the field of the updated value,

  or check the option to validate the selected value immediately, under

  Properties - Options).

• Sinlge select query in the diff for the same table (same Structure) diagrams

  Scenario:
  
  Table XYZ is created in detail a.
  After a year, the old data of the previous year could be moved to another schema. However in the other schema of the same table name would be used.
  
  For example
  
  A schema contains XYZ table with data from the year 2012
  Schema B contains XYZ table with data for the year 2011
  Table XYZ in the two schemas have an identical structure.
  
  So we can draw a single select query to read the data from the tables in an effective way.
  For example select * from XYZ so including date between October 15, 2011 to March 15, 2012.
  However, the data resides in 2 different schema altogether.
  
  
  Creating a view is an option.
  But my problem, there are ORM (Hibernate or Eclipse Top Link) layer between the application and the database.
  If the queries would be constituted by the ORM layer and are not generated by hand.
  So I can't use the view.
  So is there any option that would allow me to use only query on different scheme?

• How to update columns with the value of other lines in the same table

  Hello
  
  I use Oracle 11.2, I'd use SQL statements to update a column based on values in other rows in the same table. Here are the details:
  
  create table TB_test (number 4 myId, crtTs date, date of MDPU);
  
  insert into tb_test (1, to_date ('20110101', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110201', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110301', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110901', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110902', 'YYYYMMDD'), null);
  
  After you run the SQL code, I would like to have the following result:
  
  1, 20110101, 20110201
  1, 20110201, 20110301
  1, 20110301, null
  2, 20110901, 20110902
  2, 20110902, null
  
  Thanks for your suggestion.

  I guess you need this, otherwise please explain logic correctly:

  SQL> merge into tb_test t
    2  using (
    3    select rowid as rid
    4         , lead(crtts) over(partition by myid order by crtts) as updts
    5    from tb_test
    6  ) v
    7  on (t.rowid = v.rid)
    8  when matched then update
    9   set t.updts = v.updts
   10  ;
  
  5 rows merged.

  Setting updates with subqueries may be difficult: (.) Unfortunately my suggestions below are of the try-it-and-see-what-happens variety - nothing of certain

  First of all, check the index. Is it bitmap or tree? If the tree to see if the more restrictive columns are listed first - this can help with effectiveness of b-tree indexes. Also if the tree a composite bitmap for columns with lots of repeat values instead could help

  Its a correlated subquery so that you cannot run just the subquery first put the result in a scalar varaiable and using the variable in the SQL instead. You can try putting the keys w/join subuqery results in a TWG first to use TWG in SQL to see if I/O is reduced together during these two operations.

  You have the license for the parallel query option? Using parallel DML (this must be activated manually) can help. Check the documentation of the ALTER SESSION command to do so. In addition, the PARALLEL_INDEX() indicator could help

• Compare two rows in the same table

  Hi all
  
  I need to compare two rows in the same table, I don't know hoe to do it in pl/sql. Please help me on this.
  
  example:
  
  price of ro TR
  xya0001 AMA.7 12
  xya0003 ama6 14
  xya0004 AMA.7 16
  
  in table b is a unique value for each line, I need to compare the price column and see if the first value is less than or greater than the following value and, if there is more to put the corresponding value of br to a variable, and if it is less, put the corresponding value of the br to another variable. I don't know a method to do this, as I'm new to pl/sql. Please help me in this

  for data in(select tr,br,price, lag(price) over ( order by tr) newcol
  from yourtable)
  loop
  if nvl(data.newcol,0) > data.price then
