Value = Parent Stock Category Id; my Param = data Adapter. So if you edit a cell in the Datagrid, the unnderlying row's Row State will be changed to Modified. Usually this happens because you have edited data in a datagrid for example, where this datatable is the underlying Data Source.
This is because accessing the database, locating and processing the data, and then transferring the data to the client is time-consuming.
Pulling all of the table to the client also locks all of the rows on the server.
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.
If there is no column in an existing table that matches a column found in the chapter, a new column is added.
Before the tables in the are filled with the data in the chaptered columns, a relation is created between the parent and child tables of the hierarchical rowset by adding an integer column to both the parent and child table, setting the parent column to auto-increment, and creating a , only that table will be filled.
Thanks, Rich I think I figured this out (because I finally got it to work).
Command Text = "Update tbl1 set fld1 = @p1 where ID [email protected]" da.

to retrieve all of a table takes time, especially if there are many rows in the table.
I would also advise that you break out the query into a seperate code file and remove the try/catch block. I suppose you want to want to use the Datatable table that you get from the function's parameters (from Access) and use it to update the same table in My Sql, rigth? The code compiles and runs with out error - but when I check the My Sql DB to see the updates, there is nothing there.
