-

i have table containing n columns, taking sample like

dept_id user_id data -------------------- 1             j 1       s       j 1       j       j 2       j       j 2       k       j 2       k       l 3       j       l 3       j       l

now, in case there more 1 data set dept_id contain differently set flags user_id, data set user_id = ‘j’ selected.

i have tried using 

select dept_id, user_id  deleteme  group dept_id, user_id having user_id = 'j'  order dept_id

however giving me results .

dept_id user_id --------------- 1       j 2       j 3       j

but requirement is,

dept_id user_id data -------------------- 1       j       j 2       j       j 3       j       l

please suggest.

select distinct dept_id,user_id, data   @deleteme  user_id='j'  order dept_id    dept_id user_id data -------------------- 1       j       j 2       j       j 3       j       l
