• Update statement with joins of tables and where Clause

  Hi, I have MS SQL background and I try to execute an update statement in Oracle with joins of tables. However, the syntax below does not work but I think it works for MS SQL.
  
  Basically, the base table must be attached to a master table trend with monthly snapshots, an account will be only an entry for a given date monthly. Where clause must be limited to accounts within a certain range of interest rates.
  
  The first approach returns command SQL ORA-00933 not correctly completed, and the second approach returns ORA-01427 row below query returns multiple rows. Can anyone help? Thanks in advance!
  
  
  
  1:
  
  Update PenaltyAll
  Set a.indicator = month (b.)
  of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
  where a.monthend='01/31/2009' and b.date='12/31/2008' and b.apr < 20
  
  2:
  
  Update PenaltyAll
  adjustment indicator =
  (select to_char (b., 'MM')

• Update statement with Date field

  I'm trying to run an update statement and I want to update the date in the format:
  
  04/05/2010 12:31:54
  
  If I run this query on the double it appears correctly: select the double to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM')
  
  If I run this well query on my table, I get a 'not one month valid' error.
  
  
  UPDATE WR_MEASURE_VALUE SET HOST_CORRECTED_VALUE = 35,
  HOST_CORRECTED_DATE = to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM') WHERE WR_MEASURE_VALUE_OID = 474066
  
  
  what I am doing wrong and how can I get my update statement to update date correctly in the ' HH12:MI JJ/MM/AAAA: SS PM' form?
  
  Thank you
  
  
  Guess all I had to say was HOST_CORRECTED_DATE = SYSDATE
  
  Thanks anyway

  If you want:

  'UPDATE WR_MEASURE_VALUE SET ' || p_FieldToInsertUpdate || '=' || v_ValueAfterFactored || ',' ||
                                    v_DateToUpdate || '= to_date(''' || to_char(sysdate, 'dd/mm/yyyy hh12:mi:ss PM') || ''', ''dd/mm/yyyy hh12:mi:ss PM'')'||
  ' WHERE WR_MEASURE_VALUE_OID= ' || v_MeasureValueOID_arr(i) ||
  ' AND ' || v_Current_25Month_Value || ' != ' || v_DisplayValue;
  

  But... smacks of dubious design if you do not know what columns you update at compile time, IMO.

• Update statement with join other tables

  Hello

  If all the values needed to update a given line from table_x come from the same line of table_y (or in the same row of a result set of a query on a number any of tables), then you can do something like this:

  UPDATE  table_x  x
  SET     (col1, col2, col3, ...)
  =     (
           SELECT  NVL (y.col1, x.col1)
           ,         NVL (y.col2, x.col2)
           ,         NVL (y.col3, x.col3)
           FROM    table_y  y
           WHERE   x.pkey   = y.expr
           AND         ...
       )
  WHERE   ...
  ;
  

  If the WHERE clause is based on the same line of table_y, then it will be probably easier and more efficient to use the MERGER instead of UPDATE.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
  In the case of a DML (UPDATE), for example, the sample data should show what looks like the tables before the DML, and the results will be the content of the or the tables changed after the DML.
  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).

• Update statement with a subquery

  Hello gurus,

  I am having trouble with an Update query.  Basically, I want to just update some documents in my DB Oracle (version 11.2.0.2) according to certain criteria in my WHERE clause.  That's what I have below.

  Select count (*)

  From Table_1 a, b Table_2

  Where a.unique_id = b.unique_id and b.Doc_Type = 'AP' and a.Doc_Title is null;  < == returns 540 records

  Update Table_1

  Define Doc_Title = 'data '.

  Where Doc_Title = (select a.Doc_Title

  from Table_1 a, b Table_2

  where a.unique_id = b.unique_id and b.Doc_Type = 'AP' and a.Doc_Title is null

  A.Doc_Title group);  < == lines updates 0 (I expect it, updated the 540 chronogram my query earlier than I used to check)

  Any ideas?  Thank you!

  Update Table_1 one

  Define Doc_Title = 'data '.

  When there is)

  Select 1

  in Table_2 b

  where a.unique_id = b.unique_id

  and b.Doc_Type = 'AP '.

  and a.Doc_Title is null

  )

• Update statement with joins

  Hello
  I tried to update the 50 rows in a table using joins

  Please help thsis

  You cannot update a subquery. To update the table tran instead.

  To select the 50 lines you want, your logic in the WHERE clause of the nesting.

  UPDATE tran
  SET status = NULL
  WHERE ROWID IN ( SELECT ROWID
                      FROM ( SELECT ROWID

• Is possible to write the INSERT statement that fills two columns: 'word' and 'sense' of the file text with multiple lines - in each line is followed word that is the meaning?

  Is possible to write the INSERT statement that fills two columns: 'word' and 'sense' of the file text with multiple lines - in each line is followed word that is the meaning?

  Hello

  Of course, it is possible.  According to what the text file looks like to, you can create an external table that treats the text file as if it were a table.  Otherwise, you can always read the file in PL/SQL, using the utl_file package and INSERT of PL/SQL commands.

  You have problems whatever you wantt?  If so, your zip code and explain what the problem is.

  Whenever you have any questions, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the exact results you want from these data, so that people who want to help you can recreate the problem and test their ideas.  In this case, also post a small sample of the text involved file.

  If you ask about a DML operation, such as INSERT, then INSERT statements, you post should show what looks like the tables before the DML, and the results will be the content of the table changed after the DML.

  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).

You mentioned there are about 5000, then the query joining NAP_INTERNET with PS_RF_ISNT_PROD is begun 5000 times.
  The trick is to join only once, be updated using join views - provided that it is preserved - key or by using the merge statement.

  Here is an example:

• need help with the Update statement

  Hello
  I received a question in a course and I tried my best to respond, and now my brain is giving. I would really appreciate help with the update statement. I don't mind if you do not validate a solution, a little nudge in the right direction would be really useful. I'll post that I got.
  
  THE QUESTION
  / * For these agents disabled on more than seven missions, change their date of deactivation of the first date of deactivation of all the agents that have been activated in the same year as the agent that you update currently.
  */
  
  I have it divided into parts, here is my select statement to agents disabled on more than 7 missions, which produces the deactivation_dates in the agents table that I want to update...

  SELECT
  s.deactivation_date
  FROM
  (
  SELECT
  a.deactivation_date,
  count(m.mission_id) as nomissions
  FROM
  agents a
  INNER JOIN
  missions_agents m
  on
  a.agent_id=m.agent_id
  GROUP BY
  a.deactivation_date
  ) s
  WHERE
  s.nomissions>7 AND s.deactivation_date IS NOT NULL

  .. .and the code for the first date of deactivation for each year of activation agent

  select 
  a2.deactivation_date
  from
  agents a2
  where a2.deactivation_date= 
  (
  select min(a.deactivation_date)
  from 
  agents a
  where to_number(to_char(a.activation_date,'YYYY'))=to_number(to_char(a2.activation_date,'YYYY'))
  )

  ..... I am not real to marry these two statements together in the Update statement. I can't extract each date of deactivation produced in the first select statement and their match against the first date of deactivation in the year they have been activated for the second select statement.
  
  Any help greatly appreciated... :))

  I began to wonder how things would :)

  First of all why he chooses the date the earliest of all agents

  UPDATE  AGENTS_COPY AC /* (1) */
  SET     DEACTIVATION_DATE = (
  SELECT  MIN(AGS.DEACTIVATION_DATE)
  FROM    AGENTS_COPY  AGS
  ,       AGENTS_COPY AC /* (2) */
  WHERE   TRUNC(AGS.ACTIVATION_DATE,'YEAR') = TRUNC(AC.ACTIVATION_DATE,'YEAR') /* (3) */
  )
  

  He recovers as soon as the subquery has not been correctly set in the SET clause. It seems you are trying to update a correlated, but we are still having a conceptual shift. I have added a few comments to your code above and below will explain.

  (1): when you do a correlated update it is useful to the table alias that you did right here.

  (2): this table statement is not necessary and is the reason why the FIRST deactivation date is selected. The alias that you use (3) refers to THIS table, not the one defined in the update statement. Remove the line indicated by (2) in the FROM clause and a correlated update will happen.

  and secondly why is it to update each row, when I thought that I'm just the lines where the agents are disabled and missions > 7? Pointers on where I'm wrong would be very appreciated. (SQL = stupid query language!) :)

  WHERE EXISTS
  (
  SELECT
  a.agent_id,
  count(m.mission_id)
  FROM
  agents a
  /* INNER JOIN AC ON AC.AGENT_ID = A.AGENT_ID */
  INNER JOIN
  missions_agents m
  ON
  a.agent_id=m.agent_id
  GROUP BY
  a.agent_id,
  a.deactivation_date
  HAVING
  count(m.mission_id)>7 AND a.deactivation_date IS NOT NULL
  )
  

  Once again this problem is similar to the question above that a correlation update doesn't work. Test existence of lines in an EXISTS subquery. Since your subquery is not related to the table that you are trying to update, it will be always return a line and, therefore, it returns true for EACH LINE in the AGENTS table. To limit the game to only agents > 7 missions results, you need to add a join condition that references the table in your update statement. I added one above (with comments) as a sample.

  I recommend you look over all material that you have associated with correlated subqueries, including documents that I posted above. This seems to be what you're having the problem more with. If you need me to explain the concept of correlated queries any better please let me know.

  Thank you!
