Guest Posted: Tue Feb 17, 2004 10:29 am    Post subject: Filtering affect update? I have some filtered rows in my filtered table. When I try to change one field I got next message: "Key column information is insufficient or incorect. Too many rows were affected by update." I tried to change data in Field (MEMO Type from DBMemo) which is different from criteria field. You How I can change data without problems?

Too many rows were affected by update." Check if the table has a primary key. -- Mike Collier www.adoanywhere.com Back to top HarisCo! Guest Posted: Wed Feb 18, 2004 7:26 am    Post subject: Re: Filtering affect update? That's correct. But I must have duplicate values in field of my Primary table. Because of that I use AfterScroll. I try to make relations with filtering. I can not setup two keys in MasterField property. Can you give me advice, Thank's Back to top HarisCo!

Good Luck Back to top Viatcheslav V. Vassiliev Guest Posted: Wed Feb 18, 2004 11:44 am    Post subject: Re: Filtering affect update? And you will have the same problem when calling UpdateBatch(). You should add additional column that will be unique and make it primary key. //------------------------------------------ Regards, Vassiliev V.
