KalLimit on number of 'WHERE ' Statements?
Hi!
Wondering if anyone has an idea on the Max number of 'WHERE ' Statements possible!
Browsed through the available docuementation on 'WHERE ' but no luck yet
My client here seem to be running queries with thousands of WHERE's and now trying to convert to WF.
I've suggested to use 'WHERE
IN FILE ' instead, but was wondering if there is any better way of overcoming the limitations?
Thank you!!

PrarieFrom the IBI site.
There is no limit to the number of WHERE statements in a FOCEXEC.
There is a limit to the number of test values in a WHERE statement.
Currently the buffersize to contain test values is 16,000 bytes for a
WHERE statement against a FOCUS database or relational table.
NOTE:The buffersize for an IF statement is 32,737.
The buffersize for SUFFIX=FIX or VSAM files is 3,200 for WHERE or IF
statements.

GCohenThe size of the WHERE buffer used to be 32,000 characters. In the latest release this is probably unlimited. BUT, the database may have a limit on the maximum number of characters in a WHERE clause, and that was the reason we had a 32,000 limit.
