I have no idea what SQL_PrepareUpdate returns as it's clearly a custom written function so show that, and if you must check for valid handles, if that's what index represents, do the check like this:

pawn Код:

if (DB:index > 0)

Why could it be NULL is either the database file doesn't exist, query has an error, or the user couldn't be found in the table and others...
