ASP.Net Configuring data source question

because I have a table named WorkAttendance,
On the ASP.net website, I want the gridview to view only the  workattendance of the currently logged in employee.


ex:
SELECT * FROM WorkAttendance
Where employeeID = "the employee id of the user that is logged in"
 
the employee id of the user is session["employeeID"]
what is the correct statement for it??
