I am pulling data from one SQL Server database, formating the data and then inserting it into another SQL Server Database. I am looking for a faster way to do this than the one I am currently using. The data pull is about 37,000 rows, so formating it and inserting it one row at a time is very time consuming. I was hoping I could format it into a datatable and insert the datatable into second database essentially inserting all rows at the same time as if they wre within the same databse, but I have not found a way to do this.
Essentially the code (I have simplified it) that I am using...
Dim
cn1 As New SqlClient.SqlConnection
Dim cn2 As New SqlClient.SqlConnection
Dim cmd1 As New SqlClient.SqlCommand
Dim cmd2 As New SqlClient.SqlCommand
[Code] .....
I am INSERTING into 2 different tables with 2 different buttons (One after the other by clicking each button). I have a form with 1 button directly on it to INSERT into tblCustomers from a field that is directly on the form as well. I then have a TabControl with another button with other fields (5 to be exact).
After I add data to the data base by filling out the field on the form and then by first clicking the add button located directly on the form and then add data to the fields directly on the TabControl the data will not INSERT itself into the tables in the data base for the 2nd table. Only the first table get data in it and not the one related to the TabControl.
BUT if i add data in the TabControl and then click the button on the TabControl it adds data into to the 2nd table. Is there a way to refresh my program so that it will accept both the "forms data" and the "TabControl data"?
