[RESOLVED] Update command in vb.net,asp.net
My program is doing good when I suddenly bumped into this problem.
I dont know how to do the next functionality that I need to accomplish.
I am done with inserting values, showing the gridview etc and it works great. Now my problem is the update command.
I have 2 tables
Now, when I run my update command in sql server, it works great! I just right click the database, click new query and i run this command:
update tblDest set DestEmail =(Select SourceEmail from tblSource where tblSource.SourceFname = tblDest.DestFname and tblSource.SourceLastname = tblDest.DestLastname)
what the query does, is it updates the table tbldest email where lastname and firstname exists in both tables that are equal,
the question is, I want to automate this, I am done with inserting values, the problem is, I dont know how to run the update command,
I tried doing this:
Dim sqlds As New SqlDataSource
sqlds.ConnectionString = ConfigurationManager.ConnectionStrings("sqlconnect").ConnectionString
sqlds.ProviderName = ConfigurationManager.ConnectionStrings("sqlconnect").ProviderName
sqlds.UpdateCommand = "update tblDest set DestEmail =(Select SourceEmail from tblSource where tblSource.SourceFname = tblDest.DestFname and tblSource.SourceLastname = tblDest.DestLastname)"
DestGrid.DataSource = sqlds
but nothing happened.
I want to thank you guys in advance for any help.
