Question

I have two tables, one that defines lists and another that defines items in the lists. When i run this i only get lists that have items referencing them. i really need to get a result for all rows in the lists table and a count of how many rows in the items table reference each list.

SELECT name, COUNT(items.listId) as itemCount
FROM lists 
INNER JOIN items 
ON lists._id = items.listId
GROUP BY items.listId

any help would be much appreciated.

Answer 1

Try changing your INNER JOIN to a LEFT OUTER JOIN, and change your GROUP BY to lists._id. I didn’t test this!
