Execute Immediate for an IF statement

• FORALL with EXECUTE IMMEDIATE

  Hi all
  
  I'm using Oracle 11 g Release2.
  
  I need to use the forall with EXECUTE IMMEDIATE statement and the content of string inside EXECUTE IMMEDIATE is a SELECT instead of the usual DML statement.
  
  Objective: In this SELECT statement, I'll be passing of data using the "USING" clause in FORALL statement
  
  When I try to use it, am getting error found "no DATA".
  
  Please advice if I use FORALL and EXECUTE IMMEDIATE on a SELECT statement?
  
  I can share the scenario...
  
  Thank you!

• The concatenation of the EXECUTE IMMEDIATE statement.

  Hi all
  
  The situation is that I am trying to find all customers whose Date of birth (DOB) is greater than or equal to 150 days. Unfortunately, when I run this SQL I get the error message:
  (1) ORA-00904: "FEB": invalid identifier
  (1) ORA-06512: at line 4 level
  
  I'm not sure what I should do to solve this problem, I hope you can help.
  
  Note: I have to encapsulate this statement in an immediate execution due to problems of roles/Privilidge. In the full version, I also use AUTHID CURRENT_USER.
  
  
  

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
      EXECUTE IMMEDIATE ' SELECT  cust_name,
                                  cust_dob, -- date of birth
                                  cust_shoe_size

  The right way to use dynamic queries like this would get stuck in the variables you use... for example

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
      EXECUTE IMMEDIATE ' SELECT  cust_name,
                                  cust_dob, -- date of birth
                                  cust_shoe_size
                          FROM    tblCustDetails c
                          WHERE   SUBSTR(c.cust_name, 1,7) = ''Bob''
                                  AND cust_dob >= NEXT_DAY(:1 - 150 , ''SATURDAY'')
                           ' USING curr_date;
  END;
  

  However, you also have to take into account the fact that the results of the query are currently disappearing into the ether, so you need an INTO statement...

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
      EXECUTE IMMEDIATE ' SELECT  cust_name,
                                  cust_dob, -- date of birth
                                  cust_shoe_size
                          FROM    tblCustDetails c
                          WHERE   SUBSTR(c.cust_name, 1,7) = ''Bob''
                                  AND cust_dob >= NEXT_DAY(:1 - 150 , ''SATURDAY'')
                           ' INTO var1, var2, var3 USING curr_date;
  END;
  

  ensure that your variables are declared as appropriate, and then...

  ... you have to take into account the possibility that there is more than 1 line returned, in which case you will have the results of the query to a collection.

  Of course, it is useless for dynamic SQL statements in the first place...

  DECLARE
      curr_date Date := SYSDATE;
  BEGIN
    SELECT  cust_name,
            cust_dob, -- date of birth
            cust_shoe_size
    INTO    var1, var2, var3
    FROM    tblCustDetails c
    WHERE   SUBSTR(c.cust_name, 1,7) = 'Bob'
    AND     cust_dob >= NEXT_DAY(curr_date - 150 , 'SATURDAY');
  END;
  

  still, you should always take into account the bulk collection in a collection if it were going to be more than one row returned.

• dml execution 2 statements at a time with the help of execute immediate

  I would like to run 2 DML statements at a time with the help of execute immediate usefulness,.
  
  ex:
  
  update employee set ename = 'Chantal' where eno = 123;
  Update dept set dname = 'IT' where dno = 345;
  
  I want the two statement to execute at a time, but I don't want to use any loop as well.
  
  Thanks in advance

  You can use:

  execute immediate 'begin update employee set ename='jagadeesh' where eno=123; update dept set dname='IT' where dno=345; end;';
  

  Although updates will always run one after the other.

  If you want the simultaneous treatment, then you need to use DBMS_JOB and DBMS_SCHEDULER to plan both work to run to run each of the statements independently.

• suffixing date in the EXECUTE IMMEDIATE statement

  Hi could one please let me know how I can the suffix of the name of the table to the year, which the calculation is being in the select statement. Output should be as an example: test_2007

  declare
  
  abc number;
  
  begin
  
     select (to_char(sysdate, 'YYYY') - 4) into abc from dual;
  
     EXECUTE IMMEDIATE 'CREATE TABLE test_&abc as select * from emp where 1=2';
  
  end;

  You can do it like this

  BEGIN
     EXECUTE IMMEDIATE
           'CREATE TABLE test_'
        || (TO_CHAR ( SYSDATE, 'YYYY') - 4)
        || ' as select * from emp where 1=2';
  END;
  

  You can use your variable as well, if this can change dynamically.

  DECLARE
     abc            NUMBER;
  BEGIN
     SELECT (TO_CHAR ( SYSDATE, 'YYYY') - 4) INTO abc FROM DUAL;
  
     EXECUTE IMMEDIATE 'CREATE TABLE test_'||abc||' as select * from emp where 1=2';
  END;

• use of execute immediate with variables

  Hello

  I want to update a table with immediate execution, but I need to use the variable to run immediately. I typed a code, but the code below does not work and I m getting the error ORA-00936. Something wrong with this code?

  WHILE v_acu_payment_amount > 0

  LOOP

  BEGIN

  SELECT emplid, amount_past_due

  IN v_emplid, v_vade_tutari

  OF vade_temp

  WHERE the sira = v_sirano AND emplid IN (r1.emplid);

  END;

  v_acu_payment_amount: = v_acu_payment_amount - v_vade_tutari;

  Dbms_output.put_line ('paymentamount2' | v_acu_payment_amount);

  IF v_acu_payment_amount > 0

  THEN

  EXECUTE IMMEDIATE "update vade_temp set AMOUNT_PAST_DUE = to_number('||) 0

  || ') where sira = to_number (')

  || v_sirano

  || ')';

  ON THE OTHER

  Temp: = v_acu_payment_amount * (-1);

  Dbms_output.put_line (temp);

  EXECUTE IMMEDIATE "update vade_temp set AMOUNT_PAST_DUE = to_number (')"

  || ') where sira = to_number (')

  || v_sirano

  || ')';

  END IF;

  COMMIT;

  v_sirano: = v_sirano + 1;

  END LOOP;

  Kind regards

  Gunce

  In addition, you have no dynamic SQL for this

  [code]

  WHILE v_acu_payment_amount > 0

  LOOP

  BEGIN

  SELECT emplid, amount_past_due

  IN v_emplid, v_vade_tutari

  OF vade_temp

  WHERE the sira = v_sirano AND emplid IN (r1.emplid);

  END;

  v_acu_payment_amount: = v_acu_payment_amount - v_vade_tutari;

  Dbms_output.put_line ('paymentamount2' | v_acu_payment_amount);

  IF v_acu_payment_amount > 0

  THEN

  UPDATE vade_temp

  SET amount_past_due = 0

  WHERE the sira = v_sirano;

  ON THE OTHER

  Temp: = v_acu_payment_amount * (-1);

  Dbms_output.put_line (temp);

  UPDATE vade_temp

  SET AMOUNT_PAST_DUE = temp

  where sira = v_sirano;

  END IF;

  COMMIT;

  v_sirano: = v_sirano + 1;

  END LOOP;

  [/ code]

  But if you need dynamic sql statements, then you should use bind variables as

  ...

  EXECUTE IMMEDIATE "UPDATE vade_temp SET amount_past_due =: b1 WHERE sira =: b2' using 0, v_sirano;"

  ...

• Execute Immediate with DOF and TABLE() - error ORA-22905

  Hello

  I have a problem trying to use a user defined the Type of the Table in a statement Execute Immediate containing a CREATE TABLE statement.

  Is there no work around for this problem?

  The actual code for the SELECT * OF TABLE(:T) is dynamic and slow. That's why I try to avoid to create/fill the table in two steps (as does with MY_TABLE1). Also, in this case, I can't use SELECT * but must specify all the columns (amount variable and over 100 columns).

  CREATE TYPE MY_TABLE_TYPE AS TABLE OF VARCHAR2(30);
  /
  DECLARE
      MT MY_TABLE_TYPE;
  BEGIN
      SELECT * BULK COLLECT INTO MT FROM DUAL;
      -- Two steps
      EXECUTE IMMEDIATE 'CREATE TABLE MY_TABLE1 (A VARCHAR2(30))';
      EXECUTE IMMEDIATE 'INSERT INTO  MY_TABLE1    SELECT * FROM TABLE(:T)' USING MT; -- OK
      -- One step
      EXECUTE IMMEDIATE 'CREATE TABLE MY_TABLE2 AS SELECT * FROM TABLE(:T)' USING MT; -- ERROR ORA-22905   
  END;

  In my view, the error message is incorrect or the less misleading. Bind variables cannot be used in DDL:

• How to run execute immediate with variables

  Hi friends,
  How to run execute immediate with variables in v_stmt below?
  I don't know how to declare value I have here.
  

  Set serveroutput on;
  DECLARE
     i        VARCHAR (20);
     v_stmt   VARCHAR2 (100);
  
     CURSOR c
     IS
        SELECT sqlid FROM temp1;
  
  
  BEGIN
     OPEN c;
  
     LOOP
        FETCH c INTO i;
        EXIT WHEN c%NOTFOUND;
        DBMS_OUTPUT.put_line (i);
        v_stmt := 'select * from table(dbms_xplan.display_cursor('&i',null))'
        execute immediate v_stmt;
     END LOOP;
  
     CLOSE c;
  END;
  /

  Regds,
  Kunwar.

  You must first use a variable binding (named ': v' in the SQL statement in my example):

  set serveroutput on;
  DECLARE
     i        VARCHAR (20);
     v_stmt   VARCHAR2 (100);
  
     CURSOR c
     IS
         -- modified for a quick test
        SELECT sql_id FROM v$sql where child_number > 2;
  
  BEGIN
     OPEN c;
  
     LOOP
        FETCH c INTO i;
        EXIT WHEN c%NOTFOUND;
        DBMS_OUTPUT.put_line (i);
        v_stmt := 'select * from table(dbms_xplan.display_cursor(:v,null))';
        execute immediate v_stmt using i;
     END LOOP;
  
     CLOSE c;
  END;
  /
  

  However because your SELECT statement returns multiple lines, you need to adapt your code to process all rows returned (as already suggested in first response to your message).

  Instead of using the PL/SQL, I recommend you to generate a SQL file using only SQL, and then run the generated SQL file.
  For example:

  spool edx.sql
  set serveroutput on
  declare
  v_stmt varchar2(100);
  v_q char(1):='''';
  begin
  dbms_output.put_line('spool edx.log');
  for s in (select sql_id from v$sql where child_number >2)
   loop
    dbms_output.put_line('select * from table(dbms_xplan.display_cursor(' || v_q || s.sql_id || v_q || ',null));');
   end loop;
   dbms_output.put_line('exit');
  end;
  /
  spool of
  

  This generates a file similar to:

  spool edx.log
  select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));
  select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));

• How to set multiple parameters in a sql EXECUTE IMMEDIATE

  I want to set nls_language and nls_date_language and set them as different languages. fnd_global.set_nls_context () does not work. So I think I can use the EXECUTE IMMEDIATE and add them together into a single statement. But I don't know how to make that happen. Can someone help me? Thank you very much.

  Hey, thanks for your reply, I forgot to mention that it should be in the begin-end block, do you know how?

  EXEC is a more SQL API which can be used to execute the PL/SQL code. What it does is put the PL/SQL code in a BEGIN block... END of block and run.

  So, you can also manually put code in a BEGIN block... END of block and run like that.

  SQL> begin
    2     execute immediate q'[begin execute immediate 'alter session set nls_date_language = ''AMERICAN'''; execute immediate 'alter session set nls_language = ''AMERICAN'''; end;]';
    3  end;
    4  /
  
  PL/SQL procedure successfully completed.
  
  SQL> 
  

  And I don't understand what possible benefit he made a single run in a BEGIN block... Terminate during execution of multiples.

  Why this code is not in your interest, something like this

  begin
       execute immediate 'alter session set nls_date_language = ''AMERICAN''';
       execute immediate 'alter session set nls_language = ''AMERICAN''';
  end;
  /
  

• Use of EXECUTE IMMEDIATE with XML

  Database version: 10.2.0.3.0 - 64bi
  
  Hi all
  
  I have an xml that is stored in a table, xmltype column.
  I target insert tables including column names and xml nodes are the same.
  using the table of all_tab_columns I will generate columns must be passed to xmltable.
  all these data, I'll store them in variables and finally proceed to xmltable as below
  I just want to know using execute immediate is good to use XML?
  
  SQL_STMT: = 'insert'. table_name | ' ( '|| V_COLUMN_NAME |') ' ;
  SQL_STMT: = SQL_STMT | ' SELECT '. V_XTAB_COLUMN_NAME |
  "FOR TO_XML,
  XMLTABLE(' || v_xpath ||)
  "PASSAGE XML_VALUE
  columns | V_COLUMNS_DATA_TYPE
  ||') XTAB
  WHERE Seq_NO = ' | P_SEQUENCE_NO;
  
  RUN IMMEDIATELY SQL_STMT;
  
  Thank you and best regards,
  Ruby

  Hi Ruby,

  I just want to know using execute immediate is good to use XML?

  Sorry, but this question does not make much sense.
  Whether or not dynamic SQL means XML is not relevant, the statement will end up as a cursor in the shared pool independently and be executed or retrieved as any other.

  If I were you, I'd be worried on the statement do not use bind variables, or the need for dynamic SQL in the first place.

  Why should you use dynamic SQL?
  If it's laziness, because there are a lot of columns to write down, then it is a bad reason.

• EXECUTE IMMEDIATE throws exception NO_DATA_FOUND when it should not

  Hi all
  
  I wrote an anonymous PL/SQL block that, on paper, should be OK, but one of its commands EXECUTE IMMEDIATE is runnning slowing prematurely and throw an exception NO_DATA_FOUND, when it should not because I know that there is data in the table.
  
  Here is the line that I suspect is out of steam after 8 attempts:
  
  
  ---
  immediately execute "INSERT INTO ple101.circular35 (ID, SLAVETABLEID, SLAVEITEMID, MASTERTABLEID, MASTERITEMID, PRO) (SELECT * FROM SLAVETASKS where mastertableid =' |)" subTableID | "and masteritemid =' |" subitemID |' and subtableid =' | mastTableID | "and SLAVEITEMID =' |" mastItemId |') ' ;
  ------
  
  It is supposed to search the entire SLAVETASKS table for documents that match the WHERE clause, but gives up after 8 cycles.
  Table SLAVETASKS got 10228 records.
  
  The above statement (and the whole of the PLSQL block) is good in that it gets records if they are wthin the first 8 records in the SLAVETASKS table, but like I said after 8 records, to throw an exception NO_DATA_FOUND.

  Hi Goofy,

  The above script is for PLSQL and if you want to display the data in circular 35 follow like that

  # Save the code below in the sqlscript for example. circular_process_display. SQL and run as

  sqlplus /@ @circular_process_display.sql

  -- CREATE TABLE circular 35
  CREATE TABLE circular35
  ....
  ..
  /
  
  -- Execute PLSQL Block as given in my earlier post
  DECLARE
  ...
  BEGIN
  ...
  EXCEPTION
  ...
  END;
  /
  
  -- Run SQL to display output on screen.
  SET SERVEROUTPUT ON SIZE 100000 FEEDBACK ON LINESIZE 200;
  
  SELECT *
  FROM circular35
  /
  
  {code}                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
  

• Execute Immediate is not working well

  We need to find tables with the same name and columns but these columns whose data type is different. The SQL below detects the difference.
  

  select a.table_name, a.column_name, 
  a.data_type ||'---> '||a.owner BASE_SCHEMA_TYPE, 
  b.data_type ||'---> '||B.owner COMPARED_SCHEMA_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

  Based on the SQL above, I created the procedure mentioned below which takes a base as input parameter schema and find these tables with the same name but have different data type columns. It generates dynamic SQL code properly (you can see in DBMS_OUTPUT) but for some reason, the INSERT is not the case with EXECUTE IMMEDIATE. No idea why?
  

  create or replace procedure admin.compare_data_types (p_baseschema in varchar2)
  is
  v_sql   varchar2(2000);
  begin
  
  delete from admin.differences;
  commit;
  
  for rec in (select  username from  dba_users where Username IN ( 'HR'))
  loop
  
    v_sql := 'insert into admin.differences select a.table_name, a.column_name, a.data_type ||''---> ''||a.owner BASE_SCHEMA_TYPE, b.data_type ||''---> ''||B.owner COMPARED_SCHEMA_TYPE from all_tab_columns a, all_tab_columns b      where a.owner = '''||p_baseschema||''' and b.owner = '''||rec.username||'''  and a.table_name=b.table_name and a.column_name=b.column_name and a.data_type!=b.data_type';
       
       dbms_output.put_line (v_sql);
       execute immediate v_sql;
       --commit; -- Doesn't make any difference
       --v_sql := null; -- Doesn't make any difference
       
  
  
  end loop;
  commit;
  
  end compare_data_types;

  Structure of the table being INSERT ed

  create table admin.DIFFERENCES
  (
    TABLE_NAME           VARCHAR2(200),
    COLUMN_NAME          VARCHAR2(200),
    BASE_SCHEMA_TYPE     VARCHAR2(100),
    COMPARED_SCHEMA_TYPE VARCHAR2(100)
  )

  How about putting in a debug message to see what he does...

  (don't forget to ' set serveroutput we "before...)

  create or replace procedure admin.compare_data_types (p_baseschema in varchar2)
  is
  v_sql   varchar2(2000);
  begin
  
  delete from admin.differences;
  commit;
  
  for rec in (select  username from  dba_users where Username IN ( 'HR'))
  loop
  
  insert into admin.differences
  select a.table_name
        ,a.column_name
        ,a.data_type ||'---> '||a.owner BASE_SCHEMA_TYPE
        ,b.data_type ||'---> '||B.owner COMPARED_SCHEMA_TYPE
    from all_tab_columns a
        ,all_tab_columns b
   where a.owner          = p_baseschema  -- Procedure Paramater
     and b.owner          = rec.username
     and a.table_name     = b.table_name
     and a.column_name    = b.column_name
     and a.data_type!=b.data_type;
  
   dbms_output.put_line('Rows Inserted for '||rec.username||': '||sql%rowcount);
  end loop;
  commit;
  
  end compare_data_types;
  

  And see if it is one) enter the loop and b) the number of rows is inserted during the process.

  If it displays 0 rows inserted, then there's something of logically wrong with your select statement, as is return nothing.
