MY SQL QUERY For multiple users

Hello Experts,

Stuck with the sql query!
One table contains status and amount and users for a specific proj.
column1,column2,column3,column4
p1,wip,100,user1
p2,wip,100,user2
p3,wip,100,user3

Open in new window

And, the query I tried as
SELECT sum(column3) AS total FROM table1 WHERE column2='wip' and column4='user1' OR column4='user2' OR column4='user3'

Open in new window

This query, returns the result as required. However, if I change column2='unbilled' then also it returns the same results.

I am stuck at this position, as there might be ton's of data and we required to get this column2 and these three users were the fixed users.

Can you suggest the correction in this or any refeerence?

Thanks,
Shail

You should add parentesis:
SELECT sum(column3) AS total FROM table1 WHERE column2='wip' and (column4='user1' OR column4='user2' OR column4='user3')

Open in new window


or even better use IN operator instead of ORs:

SELECT sum(column3) AS total FROM table1 WHERE column2='wip' and column4 IN ('user1','user2','user3')

Open in new window

Try with parenthesis or order your OR's and AND's properly, like 2+2*2 is not 8, but 6 :)

Your query is actually:
SELECT sum(column3)
AS total
FROM table1
WHERE ( column2='wip' and column4='user1' )
     OR column4='user2'
     OR column4='user3'
;

Fit your desired results.
