Tableadapter update not updating

dim cmb as new SQLCommand Builder(da) I hope this helps, Cor "Rich" I think I figured this out (because I finally got it to work). This is not a guarantee of course that there cannot be something wrong. All the insert, update and delete handling for a table are made dynamicly while using the dataadapter after doing this command. Command Text = "Update tbl1 set fld1 = @p1 where ID [email protected]" da. I have never seen in this newsgroups or by myself a real wrong behaviour of the commandbuilder. I have seen too, that some of those who wrote that in past are now advising the commandbuilder. The Select reads the database confirm the keys as are in your dataset. You can see those original rows by writing an dataset with changes to disk using ds.write XML("path", xmlwritemode.diffgram) I hope to makes it something more clear. I looked at your website, but I came up with another method using data Row. I have been reading several columns/articles that advise against using the command Builder. Thanks, Rich Rich, I have seen those messages about the commandbuilder as well. Add(New Sql Parameter("@Original_Auto Id", Sql Db Type. Input, False, nb, nb, _ "Auto Id", Data Row Version. Original, Nothing)) ' What you see is that there is a Update and a Select in it. The Update Command on my Data Adapter seems to work now. Add(New Sql Parameter("@p1, Sql DBtype.varchar, 10, "fld1") Dim dr As Data Row = tblx. Update(tblx) '--now I can see the update in tblx/tbl1 the example using cmd was only updating tbl1 on the sql server. Update(tblx) '--tblx/tbl1 not getting updated here. But if I do this---then it works OK (not using data Adapter though) Dim cmd As New Sql Command cmd. May I ask what the Select statement in the Update Command performs? Add(New Sql Parameter("@Original_What Ever", _ Sql Db Type. Input, False, nb, nb, _ "What Ever", Data Row Version. Command Text = "Update tbl1 set fld1 = 'test' where ID = 1" da. Dim da As New Sql Data Adapter("Select * from tbl1", conn) dim tblx As New Data Table da. Command Text = "UPDATE Sample SET What Ever = @What Ever WHERE (Auto Id = @Original_Auto Id) AND (What Ever = @Original_What Ever OR @Original_What Ever IS NULL AND What Ever IS NULL); " & _ "SELECT Auto Id, What Ever FROM Sample WHERE (Auto Id = @Auto Id)" I use a Select statement in the Insert Command in order to retrieve @@Identity from a sql table. Thanks, Rich Rich, Your update command is incomplete, with a dataadapter you normally test if there is no problem with the optimistic concurrency. Have a look at this most simple sample on our website. ...2-d7c12bbb3726 If you have a simple update as this mostly the commandbuilder makes your life much easier. Like the designer it can only use one not joined table with a primary key and hold a maximum of 100 fields. "Rich" wrote: Dim da As New Sql Data Adapter("Select * from tbl1", conn) dim tblx As New Data Table da. In my idea is there nothing wrong with the commandbuilder for simple updates of one table. The dataadapter checks if everything is still the same to the original rows which are still in your dataset before you do acceptchanges or that the dataadapter does that acceptchanges.
