What's wrong with doing 2 update statements? I'm pretty sure you'll have to use 2 if you want to update 2 separate tables.

You can't update two tables at once in SQL. However you could wrap both updates within a begin transaction / commit pair to ensure that they are treated as a "single" update.

You might also consider linking the two updates with an OUTPUT clause http://msdn.microsoft.com/en-gb/library/ms177564(v=sql.90).aspx[^]

Hello,

You can have multiple statements in the CommandText of a SqlCommand object. If you're doing multiple UPDATEs then you need to execute them inside a transaction so that you can rollback if there is a failure in one of the statements.
