Is there a way to insert a zero instead of NULL while performing LEFT OUTER JOIN on two tables?
Suppose I have a query like this:
SELECT * FROM
(SELECT uID from Class) T1
LEFT OUTER JOIN
(SELECT pID from University) T2
ON T1.uID = T2.pID
CASE WHEN T1.uID IS NULL
THEN 0
ELSE T1.uID
END AS uID`
Correct me if I’m wrong
