Fill(dat Table) ' Display the contents of the p (Point) column Dim r As Data Row For Each r In dat Table.
Source Column = "id" ' Fill the Data Table with UDT rows Dim dat Table As New Data Table("Points") da. Fill(dat Table) ' Display the contents of the p (Point) column Dim r As Data Row For Each r In dat Table.
The following example requires the creation of a second table containing the Point UDT column as well as a timestamp column.
Both tables are used to illustrate how to create custom command objects to update data, and how to update using a timestamp column.
The following Transact-SQL statements create the Points table and insert a few rows. Points (id int PRIMARY Key, p Point); INSERT INTO dbo.
The following example assumes that you have a Points table defined with the following structure and some sample data.
User-defined types (UDTs) are supported by using a System. Points VALUES (2, CONVERT(Point, '2,4')); INSERT INTO dbo.
Points VALUES (1, CONVERT(Point, '1,3')); INSERT INTO dbo.
Similarly a Dataset has no knowledge of the Data Source where the data is coming from.Points_ts (id, p) VALUES (2, CONVERT(Point, '2,4')); INSERT INTO dbo. Points_ts (id, p) VALUES (3, CONVERT(Point, '3,5')); INSERT INTO dbo.

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.That way you can test that it is in fact the code which is the issue or other code affecting it and additionally any error messages that the try/catch block 'absorbs' will be displayed on the webpage / debugger automatically.
