Hello,
me again. This time I would like to know if there is a clean way to determine
the type of query result from the results columns (without fetching a row)?
At the moment I am using a rather hacky way: I check if the result has only
one column named "__ASK_RETVAL". If that is the case I treat it as an
ask/boolean result.
But then I need to find out if it is a graph result and checking for name
"callret-0" is just ridiculous. So I thought if it would be feasible to check
if the returned data is a BLOB. Is that possible and using which odbc call?
Hi,
ODBC has SQLDescribeCol() for the very purpose:
