Add this to see more detailed info on the error.

pawn Код:

public OnQueryError(errorid, error[], callback[], query[], connectionHandle)
{
    print(error);
    return 1;
}

EDIT: Change this too, no need to escape single quotes.

pawn Код:

(\'%s\', \'%s\', \'%s\', \'%s\')

To

pawn Код:

('%s', '%s', '%s', '%s')

That's probably the error.
