SQL Server Update with left join and group by having
- by Marty Trenouth
I'm making an update to our datbase and would like to update rows that do not have existing items in another table. I can join the tables together, but am having trouble grouping the table to get a count of the number of rows
UPDATE dpt
SET dpt.active = 0
FROM DEPARTMENT dpt
LEFT JOIN DOCUMENTS doc on dpt.ID = doc.DepartmentID
GROUP BY dpt.ID
HAVING COUNT(doc.ID) = 0
What should I be doing?
