I have three table [tbl_user, tbl_controls, tbl_link],
tbl_user
UserID
UserName

tbl_controls
C_ID
ControlName

tbl_link
lk_id
UserID
C_ID
Status (bit)

the control is placed in the tbl_control, and assign control status is placed in tbl_link, I want to load app control in a grid view but the relevant status is marked tick by the reference of UserID.

How i accomplished this.

THanks
Regards

What I have tried:

SELECT        tbl_controls.ControlName, tbl_link.Status
FROM            tbl_controls left outer JOIN
                         tbl_link ON tbl_controls .C_ID= tbl_link .C_ID
WHERE        (tbl_link.Status IN
                             (SELECT        Status
                               FROM           tbl_link AS tbl_link_1
                               WHERE        (UserID= 30)))

I'm not sure i understand you well, but... try this:

SQL

SELECT TC.ControlName, TL.Status
FROM tbl_link AS TL
    INNER JOIN tbl_user AS TU ON TL.UserID = TU.UserID
    INNER JOIN tbl_controls AS TC ON TL.C_ID = TC.C_ID
WHERE TL.USerId =30

Hi,
Maciej Los.
Thanks for the reply.
But the thing i want to accomplish is that,
All record in the Control table display along with status and based on user id status shows true for those controls that are assigned to the user.

Hope you understand what i am trying to say.

Thanks for the help.

Does above query does not meet your criteria? Have you tested it?
