c dataadapter not updating-15

The data in the datatable comes form an Access DB, I add this to a My Sql Data Adapter and then use My Sql Command Builder to create the insert command.

The code compiles and runs with out error - but when I check the My Sql DB to see the updates, there is nothing there.

All your insertions, updates, and deletions will be effected by the single button.

Hi All, I am having a lot of trouble updating a table in a My SQL database with the contents of a datatable in c#.

string query String = "SELECT Customer ID, Company Name FROM dbo. A Using connection As Ole Db Connection = New Ole Db Connection( _ "Provider=MSData Shape; Data Provider=SQLOLEDB;" & _ "Data Source=(local); Integrated " & _ "Security=SSPI; Initial Catalog=northwind") Dim adapter As Ole Db Data Adapter = New Ole Db Data Adapter( _ "SHAPE " & _ "APPEND ( AS Orders " & _ "RELATE Customer ID TO Customer ID)", connection) Dim customers As Data Set = New Data Set() adapter.

Customers"; Sql Data Adapter adapter = new Sql Data Adapter(query String, connection); Data Set customers = new Data Set(); adapter. Columns("Customer ID")) Dim p Row, c Row As Data Row For Each p Row In customer Orders. This is what triggers the Data Adapter to perform an UPdate, an insert or a Delete on that particular row when you call the adapter's Update method.
