Hello all,

please conside the following table "photo"

id       employee_id      photo_name
1         2                abc.jpg
2         2                xyz.jpg
3         5                acd.jpg
4         2                sis.jpg
5         3                sfs.jpg
6         5                iii.jpg

now what I want is this table should select all the fields with unique employee_id (i.e. query should select total 3 rows with employee id 2,3,5) and everythime the query should select different picture(which can be done using random() )

Can anyone help me with this problem?

Thank you,
