Nulls and Empty Strings
I have an ODBC application whose backend has been changed from Access to Oracle. There is one particular query that is causing problems. The query contains a where clause with something like "field = ''" in it. This query is intended to pick up records where field is null. If the query was modified to "field is null," it would work. However, I cannot change the application.
Is there any way to configure the ODBC driver or something so that this query would work properly? I've tried defaulting the field to '', but Oracle is still treating it as null.
(What is really frustrating is that the application NEVER populates this field!)
