I am getting a count of Records.

What I need to add is, if the count is zero or null  then show the zero has count.

SELECT Count(M_AS400_P112.PCode) AS CountOfPCode, M_AS400_P112.MaintenanceDate, M_AS400_P112.PCode INTO TodayCountAS400P112
FROM M_AS400_P112
GROUP BY M_AS400_P112.MaintenanceDate, M_AS400_P112.PCode;

MSSQL has ISNULL ... check for something similar for the AS400.

Maybe this:

SELECT Count( Nz(M_AS400_P112.PCode , 0 ) ) AS CountOfPCode, M_AS400_P112.MaintenanceDate, M_AS400_P112.PCode INTO TodayCountAS400P112
FROM M_AS400_P112
GROUP BY M_AS400_P112.MaintenanceDate, M_AS400_P112.PCode;

With no criteria specified, why would the count be zero?
Just curious...?
In other words, what is this query seeking to display?


If there are many PCode, then you should include this table in the query.
Then set a left Join to show all records from the PCode table.

Something like this to get a count of all orders for each employee, while displaying Zero for any employee with no orders:
SELECT Count(Orders.OrderID) AS CountOfOrderID, Employees.EmployeeID
FROM Employees LEFT JOIN Orders ON Employees.EmployeeID = Orders.EmployeeID
GROUP BY Employees.EmployeeID;
