Question

I am creating a summary report with columns Status, Count, and Amount. How do I list a status even if no records in the query result match that status? Sample data offered in below image:

When I query for the report (counting those records in the table that match the Status), I get the following results:

How can I get the result to match the first table, which includes Status C (there are no records with a status of C)?

Use a left join. You have not included your schema but an example would be:

SELECT S.Name AS Status, COALESCE(COUNT(T.*),0) AS [Count], 
    COALESCE(SUM(T.Amount),0) AS Amount
FROM Status S
LEFT OUTER JOIN myTable T ON S.Id = T.StatusId
GROUP BY S.ID, S.Name
