Hi all !
I have two tables

Users Table:
UserId(Primary Key)
username
fname
email


Photos table:
photoid (Primary Key)
UserId (ForeignKey)
photoname
isactivated

In the photos table each user may have records varying from 1 to 3 (i.e max 3 photos).
But i need a query to retrieve a single record of each user from photos as well his username,fname and email from Users table.
The above query doesn't work and fetches multiple photos of each user
as each record happens to be distinct because the photoname in all of them is different.

I need each users sigle photo record along with his user table details.

Thanks in advance.

Hi,
 Here you can do this in two ways..
1. You can use you logic in front end in the following way..
   Get the userid into a varaible and compare the user Id of next useri with this variable and if it is same then skip the furthur process like displaying a Photo...

2. If you have only One photo as activated ( i.e isactivated =1 ) Then
 you can use following query..

select Max(Photos.photoid ),photoname,isactivated,username,fname,email from
photos,users where photos.isactivated=1 Group by UserId.


Thanks

If you want each users single photo record you need to check the photoid also in the where condition.

Sorry guys!
I haven't found any correct solution yet !!
Still waiting for the right solution.

Hi Leo,

This should do it...
HTH,

Chris thanks for the suggestion. But it doesn't solve the problem.
I also did it the same way. The reason it doesnt work is when you use distinct in the join condition then the distinct clause operates on the record level and not on the field level.
So here it will bring multiple records of the same person.
That is more than one record will be fetched from the photos table having the same UserID. Though the UserId are same but the other combination like the "photoname" make the records distinct from each other...hence no effect of the "DISTINCT" clause.

Anyways i found a way out...may be not that good,but it is effective.

select u.userid,u.username,u.email,p.photoname,p.isactiva ted from users u, photos p where u.userid=p.userid and p.id in (select max(id) as id from photos group by userid)
