Hello
I would like to know, how to realize this Left join type:
A Visual Explanation of SQL Joins
SELECT * FROM TableA
LEFT OUTER JOIN TableB
ON TableA.name = TableB.name
WHERE TableB.id IS null
id name id name
-- ---- -- ----
2 Monkey null null
4 Spaghetti null null
Where this middle part is excluded?
Thanks.
Hi,
This is left join without WHERE TableB.id IS null part.
I need to keep only these entries, where are no matches...
