Update multiple rows to NULL when NOT NULL





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

Using SQL Server 2012 - I'm trying to update a column to NULL where the column has a value in it and is meeting other conditions, but I always get error:




The subquery returned more than one value. This is not allowed if the subquery follows =,! =, <, <=,> Or> = or is used as an expression.




Here is what I tried so far:



UPDATE tblUsers
SET MobilePhoneNumber = CASE WHEN MobilePhoneNumber IS NOT NULL THEN NULL
ELSE MobilePhoneNumber
END
WHERE IsDisabled = 1
AND ValidTo IS NOT NULL
AND Id IN (SELECT Id FROM tblUsers
WHERE IsDisabled = 1 AND ValidTo IS NOT NULL)

UPDATE tmp
SET MobilePhoneNumber = NULL
FROM tblUsers tmp
INNER JOIN tblUsers tu ON tmp.Id = tu.Id
WHERE tmp.IsDisabled = 1 AND tmp.ValidTo IS NOT NULL
AND tmp.MobilePhoneNumber IS NOT NULL


Please advice.

    Tag your question with the database you are using. Neither of the queries you have shown should generate this error.
