UpdateCommand problem

[stuart_dent]

I have a SQL Server table with in Indetity column (value auto
generated).

I have tried to write my own updatecommand code.

I can't get it to work.
An error says that says Sku and rid are invalid column names. I don't
know why.

I even modified the Updatecommand the a bare bones
"UPDATE dbo.test1 SET sku = @SKU"
At least this gave me a different error!
The error says error in Prepared statement
"@SKU(20) Update dbo.test1 SET sku = @SKU"

Can anyone help?

Thanks,
Stu
