Summary:  What's wrong with the dynamic SQL below?

Details:   When the SQL below was run, it generated the following error when the FETCH was executed:


SQL:
DECLARE my_cursor DYNAMIC CURSOR FOR SQLSA;
string  ls_sql, ls_data


    // Use the pk_column_name to get the next UID
    ls_sql = 'SELECT MAX (' + ls_pk_column + ') FROM ' + as_tablename + "; "


    // Process the dymanic sql
    PREPARE SQLSA FROM :ls_sql USING SQLCA ;

    OPEN DYNAMIC my_cursor ;
    
    
    FETCH my_cursor INTO :UID ;        <---- Error occurs on the FETCH
    
    ll_rc = sqlca.sqlCode
    IF (ll_rc = 0 AND NOT (IsNull (UID)) AND (UID > 0)) THEN
        
        // Success
        al_uid              = UID + 1
        lb_update_table_uid = TRUE
        
    ELSE
        MessageBox ("Get Next UID Error", "An error occurred while trying to "       + &
                        "get the next UID for the table ~"" + as_tablename + "~".~r~n "  + &
                        "~r~n sqlErrCode:  " + string (sqlca.sqlCode)                         + &
                        "~r~n sqlErrText:  " + sqlca.sqlErrText, StopSign!)
        al_uid = 0
        GOTO GOT_UID
    END IF


    CLOSE my_cursor ;



Thank You,

Olan
