Tableadapter update not updating
Command Text = "Update tbl1 set fld1 = 'test' where ID = 1" conn. This is not a guarantee of course that there cannot be something wrong. dim cmb as new SQLCommand Builder(da) I hope this helps, Cor "Rich" Thank you. It appears that the concurrency check comes from the commandtext cmd Update.
I have never seen in this newsgroups or by myself a real wrong behaviour of the commandbuilder. All the insert, update and delete handling for a table are made dynamicly while using the dataadapter after doing this command.
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.

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.
Dim da As New Sql Data Adapter("Select * from tbl1", conn) dim tblx As New Data Table da.

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.
Command Text = "Update tbl1 set fld1 = 'test' where ID = 1" conn. Dim da As New Sql Data Adapter("Select * from tbl1", conn) dim tblx As New Data Table da.
Then I updated the items in the datarow that I wanted to change. Now I can see the update in tblx(datatable) tbl1 (sql server table). It does the same with the delete and the insert by the way. 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)" cmd Update.
What I did was to assign a datarow object to the row I wanted to update and Parameters to the Update Command and modified the commandtext to use parameters. But for the code about concurrency checking focus your eyes only on that update command that is in the sample on our website.
