sql - Get separate count for each condition within group -


i trying view of table information , oracle 10g table lists counts of specific values of column in own columns each row being group value.

for example: first select :

select processed_by, count(priority) p2 agreement_activity priority = '2' group processed_by

which outputs:

processed_by                           p2 ------------------------------ ---------- alicia                                  2 christine                               2

the second select is:

select processed_by, count(priority) p1 agreement_activity priority = '1' group processed_by

which outputs:

processed_by                           p1 ------------------------------ ---------- bonita                                  2 alicia                                  6 christine                               2

what looking output values following:

processed_by                           p1         p2 ------------------------------ ---------- ---------- bonita                                  2           alicia                                  6          2         christine                               2          2

is possible?

you can use sum case expression conditional count:

select processed_by      , sum(case when priority = 1 1 else 0 end) p1      , sum(case when priority = 2 1 else 0 end) p2 agreement_activity group processed_by

p.s. if don't care p1 or p2 maybe null instead of 0 can omit else in both expressions.
