Find matching value across two different question groups

edited Apr 8, 2011 3:46AM in PL/SQL (MOSC) 10 commentsAnswered
 I'm trying to program a validation procedure that reads in each repeating value for a question and attempts to find a matching value in a question (repeating) from another question group.  Basically, I don't want the Details to execute until it has evaluated all repeats.  Here's just a sample of the data:

S.VISIT_NUMBER = 36
S.DCM_DATE =
S.REPEAT_SN = 1
S.SAENO = 02                           (Retrieves this value.  Now to look for matching value.)
 

A.VISIT_NUMBER = 30
A.DCM_DATE =
A.REPEAT_SN = 1
A.AENO = 01                             (Evaluate but don't execute.  No match yet.)


A.VISIT_NUMBER = 30
A.DCM_DATE =
A.REPEAT_SN = 1
A.AENO = 02                             (Evaluate but don't execute.  Got a match!)

Howdy, Stranger!
