ODBC WHERE Syntax Blank Data


Question:

I am using the ODBC Extender with the dBase 5.0 ODBC driver and need to use something like the following:
WHERE (address1 = '' OR city = '' OR state = '' OR zip = '')
Apparently, the syntax is correct, because the qExecDirect statement returns @qSuccess. However, its not returning any results (which I know there are). If I do a bunch of IF statements (simulating the above WHERE line) it works. I was wondering if perhaps the = '' was incorrect.

Answer:

I am not sure that is valid SQl statment. You are really trying to search for NULL data. Try using IS NULL instead of = ''.

Looks like "is NULL" works, thanks
