I have a MS Access 2003 table of employees. There are two columns. First one is the site name and second column is the status. By the following query string I can easily count those that has the status of "Completed"
SELECT employee.[Site Name], Count(employee.EID) AS [Number of Completed]
FROM employee
WHERE (((employee.[status])="Completed"))
GROUP BY employee.[Site Name]
The question is: There are some sites that are not in the list, those sites that no employee has "Completed" status. I need to list them as well but with the value 0. Any solution in Access 2003 helps me. Thanks.

You want to do conditional aggregation. In MS Access, this looks like:
SELECT employee.[Site Name],
SUM(IIF(employee.[status] = "Completed", 1, 0)) AS [Number of Completed]
FROM employee
GROUP BY employee.[Site Name];
