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
