  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).

• as with the select query

  Hello

  I have a query something like...

  Select...

  ....

  where

  b.ProdName as 'GEAR of the TREE %' or b.prodname like '% FRONT GEAR %' or b.prodname like '% BREAK 4 %k '.

  and

  b.ProdName as

  (select the name of the society of companyms

  where < some comdition >

  )

  order of 3.6

  I have blocked in:

  b.ProdName as

  (select the name of the society of companyms

  where < some comdition >

  )

  How to give a select query with like operator.

  In above query I want to b.prodname as above and the name of the company for which I give condition.  Company names are stored in another table and I want to select and use them with like operator.

  Thank you.

  Hello

  It is not clear what you want to do.

  One possibility is an EXISTS subquery, like this:

  ...

  WHERE (b.prodname LIKE "% of the CYCLE of the TREE" - begins with this text

  OR b.prodname LIKE '% FRONT GEAR %' - contains this text

  OR b.prodname LIKE '% BREAK 4 %k' - contains this text

  )

  AND THERE ARE)

  SELECT 1

  OF companynms

  WHERE--a condition

  AND b.prodname AS business

  )

  I hope that answers your question.

  At present, the only way I can think of to avoid a call to UTL_HTTP. SET_BODY_CHARSET is to write your own little wrapper.
  In this way, you can specify the Boolean parameter or omit it if you choose to use named parameters:

• SELECT query problem

  Hi all
  
  Need select records less where Rownum < = 100, a table in which the records are classified by a field in a query, but after stopped in the ordering of rownum gets changes.
  

   
  with t as (select 1 a,'d' b from dual 
  union select 8 a,'t' b from dual 
  union select 3 a,'u' b from dual 
  union select 7 a,'k' b from dual ) 
  select t.*,rownum from t order by 2 ;
  
  
  A B ROWNUM 
  1 d 1 
  7 k 3 
  8 t 4 
  3 u 2 

  Now I want to select records where ronum < = 2 as below, this can be done by changing only in where clause and do not touch the query select, as can do a nested query I but need to do it by changing only in where clause.
  

   
  A B ROWNUM 
  1 d 1 
  7 k 3 

  Thanks in advance
  
  Thanks and greetings

  No, there is no way to get these results by changing only the WHERE clause. As it is, you have no column or expression in the main query that indicates how the lines are classified according to b, which is exactly what to test in the WHERE clause. (Remember, ROWNUM is assigned before ORDER BY is done in the same auxiliary request). You must add a using ROWNUM or ROW_NUMBER analytic function. either way requires some preparation to be done in a subquery.

  For example, the following query has an ORDER BY clause, added to the request slot, so that ROWNUM in the main query will be more arbitrary:

  with t as (select 1 a,'d' b from dual
  union select 8 a,'t' b from dual
  union select 3 a,'u' b from dual
  union select 7 a,'k' b from dual
  ORDER BY  b                              -- Added
  )
  SELECT    t.*
  ,       ROWNUM
  FROM        t
  WHERE       ROWNUM     <= 2     -- Added
  ORDER BY  b
  ;
  

  Output:

  `        A B     ROWNUM
  ---------- - ----------
           1 d          1
           7 k          2
  

  It is no coincidence that the numbers in the column ROWNUM are 1 and 2. If you want really to arbitrary numbers (such as 1 and 3), you will need an another subquery.

• How to optimize the select query executed in a cursor for loop?

  Hi friends,
  
  I run the code below and clocked at the same time for each line of code using DBMS_PROFILER.

  CREATE OR REPLACE PROCEDURE TEST
  AS
     p_file_id              NUMBER                                   := 151;
     v_shipper_ind          ah_item.shipper_ind%TYPE;
     v_sales_reserve_ind    ah_item.special_sales_reserve_ind%TYPE;
     v_location_indicator   ah_item.exe_location_ind%TYPE;
  
     CURSOR activity_c
     IS
        SELECT *
          FROM ah_activity_internal
         WHERE status_id = 30
           AND file_id = p_file_id;
  BEGIN
     DBMS_PROFILER.start_profiler ('TEST');
  
     FOR rec IN activity_c
     LOOP
        SELECT DISTINCT shipper_ind, special_sales_reserve_ind, exe_location_ind
                   INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
                   FROM ah_item --464000 rows in this table
                  WHERE item_id_edw IN (
                           SELECT item_id_edw
                             FROM ah_item_xref --700000 rows in this table
                            WHERE item_code_cust = rec.item_code_cust
                              AND facility_num IN (
                                     SELECT facility_code
                                       FROM ah_chain_div_facility --17 rows in this table
                                      WHERE chain_id = ah_internal_data_pkg.get_chain_id (p_file_id)
                                        AND div_id = (SELECT div_id
                                                        FROM ah_div --8 rows in this table 
                                                       WHERE division = rec.division)));
     END LOOP;
  
     DBMS_PROFILER.stop_profiler;
  EXCEPTION
     WHEN NO_DATA_FOUND
     THEN
        NULL;
     WHEN TOO_MANY_ROWS
     THEN
        NULL;
  END TEST;

  The SELECT inside the LOOP FOR cursor query took 773 seconds.
  I tried to use COLLECT in BULK instead of a cursor for loop, but it did not help.
  When I took the select query separately and executed with a value of the sample, and then he gave the results in a Flash of a second.
  
  All tables have primary key index.
  Any ideas what can be done to make this code more efficient?
  
  Thank you
  Raj.

  DECLARE
    v_chain_id ah_chain_div_facility.chain_id%TYPE := ah_internal_data_pkg.get_chain_id (p_file_id);
  
    CURSOR cur_loop IS
    SELECT * -- better off explicitly specifying columns
    FROM ah_activity_internal aai,
    (SELECT DISTINCT aix.item_code_cust, ad.division, ai.shipper_ind, ai.special_sales_reserve_ind, ai.exe_location_ind
       INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
       FROM ah_item ai, ah_item_xref aix, ah_chain_div_facility acdf, ah_div ad
      WHERE ai.item_id_edw = aix.item_id_edw
        AND aix.facility_num = acdf.facility_code
        AND acdf.chain_id = v_chain_id
        AND acdf.div_id = ad.div_id) d
    WHERE aai.status_id = 30
      AND aai.file_id = p_file_id
      AND d.item_code_cust = aai.item_code_cust
      AND d.division = aai.division;         
  
  BEGIN
    FOR rec IN cur_loop LOOP
      ... DO your stuff ...
    END LOOP;
  END;

• What privileges granted to select from all the PDB files

  Why the two selected does not return the same result? Or if you want the broader question - what privileges granted to select from all the PDB files.

  
  

  I want to leave common user that I created to select and see all of the synonyms of all PDB files.
  

  
  

  conn / as sysdba

create user c##nir identified by c##nir container=all;

grant connect,dba,resource to c##nir container=all;
grant select on cdb_synonyms to c##nir container=all;

select CON_ID  from cdb_synonyms  group by CON_ID;

  CON_ID
----------
   1
   4
   11
   10
   14
   5
   8
   13
   3
   7
   15
   6
   12
   9

conn c##nir/c##nir

select CON_ID  from cdb_synonyms  group by CON_ID;

  CON_ID
----------
   1

select CON_ID  from containers(dba_synonyms)  group by CON_ID
   *
ERROR at line 1:
ORA-00942: table or view does not exist

  You must use the CONTAINER_DATA clause:

  ALTER USER ##nir set container_data = container c all = current;

  After running the above command, try to select again to cdb_synonyms and you will see the data of all containers.

• SELECT query time-out - huge table

  DBA dear friends,

  
  

  DB version 11.1.0.7.  I have a SELECT query that is running long and wedging on. Query joins the 2 tables. It is partitioned hash (16 sheets) and others are not partitioned, each table is with the same volume of data - 230 million lines.

  > Optimizer stats are not outdated

  SELECT only 1 row (as indicated in the PLAN of EXPLAIN) should be fast.

• Can I use * and the list of the column names in a select query

  PLSQL again.  Can I use * and the list of the column names in a select query, i.e. Select *, col1, col2 from Mytable.  When I do that my questions tend to the bomb.  Can do in other databases.

  Thank you

  Mike

  Hi, Mike,.

  If there is something else in the more SELECT clause *, then * must be qualified with a table name or alias.

  For example:

  SELECT Mytable. *, col1, col2

  FROM MyTable;
