Saving Datagridview Records if not(already) exists and deleting other recor

[gbhs]

Hi to all,
I have always had this problem where: if I have a datagrid with records like

RecID Name
2 Tom
5 Rich
6 Harry

To Save I will loop through the rows using the sql
IF NOT EXISTS(SELECT * FROM myTable WHERE RecID= dgv.rows(i).cells(0).value say)
BEGIN INSERT the row.(the use INSERT COMMAND)

At the end of the loop I have to delete all records whose RecID are not in the Datagrid.
My Problem is:
How do I create a kind of list of datagrid RecIDs and do something like
DELETE FROM myTable WHERE RecID NOT IN (2,5,6)

Thanks in advance

What you want to do, there is no way to do it with just SQL
