Hi.
  I can't find anywhere the answer so I hope you will help...
I run  in sqlplus  query with cursor. I need to pass each row from the cursor as parameter to the called script....Is it actually possible?
DECLARE  
   
 
  
   CURSOR c_schema IS
    select dschema from x.process_control where process_name = '....' order by schema;
      v_schema    process_control.db_schema%TYPE;
   BEGIN
    
    
   OPEN c_schema;
   LOOP
      
      FETCH c_schema INTO v_schema;
       If v_schema <> '' then
       
       @connecting_schema v_schema;   ????????????   
     EXIT WHEN c_schema%NOTFOUND;
    END LOOP;
 
    
    CLOSE c_schema;
  END;

there are two standard ways to do this.


first,  open your cursor and pass it is as a reference cursor to your procedure which would then do the fetching and processing of each row itself.

that would look like this...

declare
      v_cur  SYS_REFCURSOR;
begin
      OPEN v_cur FOR SELECT ..... <your query here>;

      your_procedure(v_cur);
end;




second,  simply fetch the values and pass them into your procedure.  I recommend using the FOR cursor loop instead of while/end.   That would look like this...


begin
     for x in (select co1, col2, col3...  <your query here>) loop
          your_procedure(x.col1,x.col2,x.col3);
     end loop;
end

Also, unless the "@connecting_schema v_schema;   ????????????  " is a valid set of PL/SQL statements, an SQL*Plus command would not recognized by PL/SQL. You would need to convert it to a stored procedure and use sdstuber's recommendation.

no, it is not possible to use pl/sql to call sqlplus scripts.

you could instead,  use shell scripting to iterate through values and call sqlplus with those parameters.

or, take the code out of your scripts and embed it within the anonymous pl/sql block.

sorry, "it's not possible" is the answer.

pl/sql is simply not the tool for doing what you're asking.

if you used a procedure instead of scripts it could work,  or if you use shell scripting it will work, or if you use external procedures or java stored procedures to invoke sqlplus it would work.  But given what the constraints you requested, it's not possible.

-- OR --

You could try something like this:


-- ---------------------------------------------------------------------
-- Execute on all schema
set pages 0 feed off ver off term off
spo /tmp/schema_exec.sql
Select "@connecting_schema "||Dschema
 From X.Process_Control
Where Process_Name = '....'
Order By Schema;
spo off
@/tmp/schema_exec.sql
