Hello to all.

I have two tables
* UsersPoints(Column- UserName , Points)
* PrizeGiven(Column- UserName , Points)

suppose i want to give prize to those users who have >100 points ( from table UserPoints) and then i will insert that username and 100 Points in PrizeGiven Table so that i can remove this user in future prise distribution( i am not removing this user and points from UserPoints Table).

"(select UserName from UsersPoints where Points >100) WHERE UserName NOT IN (select UserName from PrizeGiven where Points=100)"

But query is not working !!!

Solution 1

You made an error in the SQL syntax.

SQL

SELECT up.UserName 
FROM UsersPoints up 
WHERE 
    up.Points >100 AND 
    up.UserName NOT IN 
        (SELECT pg.UserName 
         FROM PrizeGiven pg 
         WHERE pg.Points=100
        )

Regards,

Manfred
