Here is the output of my above query i have applied distinct but till the data are duplicated because of imageurl column.. so how can i remove duplicated record from result using userid. if userid repeated then delete record.
 
In my out put you can see,that the record with all data depends on userid, but i want to delete the record repeated with same userid if they are more then 1 then delete record of same userid having imageurl with 'ss1.4sql.net...'
