SQL Updae

Hello

Having trouble with doing a SQL update. This is the first time I have used multiple tables in a project. I need the syntax to define the database and the table I think...

Dim Sql As String = "UPDATE ['Tools!Book_Out_Table'] SET Booked_in_by = @Booked_in_by, Date_In=@Date_I

The above is a snip from the code. The database is called 'Tools' and the table is called 'Book_out_Table' -  When I try using the above, and all sorts of variations of the above I either get a syntax failure message or invalid object name failure message.

I read in some help it should be [Tools!]Book_Out_Table but that did not work either.

Any idea where I'm going wrong?

thanks as ever

Peter
