stored procedure multiple call call question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,


If I had a single table targ to insert into I would do an

  INSERT INTO targ SELECT thiscol, thatcol, theothercol FROM FOO.

The problem is that I have tables targ1, targ2, targn to insert things into and a nice stored procedure myproc which does the insertion into all 3 tables - problem is that I dont see how I can effectively do 

   INSERT INTO myproc SELECT thiscol, thatcol, theothercol FROM FOO.

The only way I can work out how to do this is with another stored procedure which allows me to do:

   FOR rec IN SELECT thiscol, thatcol, theothercol
   FROM FOO
   LOOP
      PERFORM myproc(rec.thiscol, rec.thatcol, rec.theothercol);
   END LOOP;

But is there a way to do this just in SQL only without resorting to plpgsql or a language like C/Java?

thanks

c
