Well I have no idea what:
...Leads
...is supposed to mean, but the basic Syntax would be
SELECT * FROM YourTable WHERE YourTABLE.YourField=79
It looks like in your syntax you are trying to specify a .Value.
This syntax may work in VB, VBA, VB.net, ...but not really in SQL.
As an example, an actual query might look like this:
SELECT * FROM tblOrders WHERE tblOrders.EmployeeID=79
