Concurrency Error in Update.

Stacey Feldman

Below, is a sample code I have been using to test my application. I have
been tearing my hair out with this. For the code below, I used the
OleDbDataAdapter config that is generated by the VS.NET Adapter Config
wizard.

When Update is called on the adapter, I get a concurrency error. There is NO
ONE else using the database. There have been no changes to the underlying
data. I know something is wrong with the command

This has happened to others and they have posted to newsgroups, but I have
not found any answers there....does anyone know what is going on???

Please help!

Oh..I figured out what was wrong. I need to have the order of the parameters
