RE: Stored Procedures, Visual Basic 6 and LIKE clause

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

Sorry,

Actually it needs to be like this:

        BEGIN 
        declare tempvar varchar(50);
        DECLARE C1 CURSOR WITH RETURN FOR SELECT MAX ( BOX ) AS RETURNED FROM
                CLSDFILES . CLOSEDFILES WHERE BOX LIKE tempvar;
        set tempvar = '%' + criteria + '%';
        OPEN C1 ;
        END  ;
