Richard Harding Wise Nutrition Coaching | Is it possible to construct WHILE loop that uses an EXISTS function as the condition? Something like - - -
WHILE EXISTS (SELECT * FROM table1 WHERE X = 0) DO <stuff> END WHILE; At present I am doing the following: OPEN tmpCursor; SET I = ROWCOUNT(tmpCursor); CLOSE tmpCursor; WHILE I > 0 DO <stuff> OPEN tmpCursor; SET I = ROWCOUNT(tmpCursor); CLOSE tmpCursor; END WHILE; which is not very elegant.

<< Is it possible to construct WHILE loop that uses an EXISTS function as the condition? Something like - - - >> EXISTS can only be used in an SQL statement and cannot be used directly in SQL/PSM. You can find the new installation here: http://www.elevatesoft.com/203b13edbdaccs.exe Please let me know when you have downloaded it. << At present I am doing the following: >> This should be a bit cleaner: OPEN tmpCursor; WHILE ROWCOUNT(tmpCursor) > 0 DO <stuff> REFRESH tmpCursor; END WHILE; CLOSE tmpCursor; http://www.elevatesoft.com/manual?action=viewtopic&id=edb2sql&topic=REFRESH -- Tim Young Elevate Software www.elevatesoft.com |
