Hi, I'm just beginning my VS.NET 2005 adventure in C#, so maybe I'm missing something obvious. . . I created a dataset containing 3 tables, one "main" table and two lookup tables connected by a relation to the main table. Only for one of the lookup tables the wizzard generated update and delete commands. For the others only the select and insert commands are generated. Even when I these tables adapters, choose "configure" and step through the wizzard with option "generate insert, update, delete statements" under "Advanced options" set, after clicking "Finish" I still have no update and delete. So why does it work for one of the lookup tables but not for the other two in my dataset? Any hint for me? TIA, Stefan P.S.: my backend DB is Oracle10g i case tweak ERwin to generate the correct DDL script. Thanks anyway, Stefan keywords: HOWTO:, generate, update / delete, command, using, data, adapter, wizzard? description: Hi, I'm just beginning my VS.NET 2005
