Try this: Ask for the length of the data returned by your SQL-Query. $fieldcontent = odbc_result($yourResultID,"YourField") if len($fieldcontent)=0 then... If Lenght of Datastring is Zero then the string is really empty.

When I run a query, even if it is empty I still get a valid identifier for the result. How do I determine that there is nothing in the result, even though the result is valid (just empty)? I thought about odbc_fetch_row, but that moves the pointer forward and I don't want that; there may be valid info. I tried odbc_result'ing a COLUMN and it returns NULL not error, so I can't test against that. One thought is to see if all columns in my query are NULL and then "No rows were found". Is there a simpler way? How does odbc_result_all determine there is nothing present? Thanks RDB
