Problem in finding the total count

Question

my table as below:

B 002 01 1
C 002 01 1
C 002 01 2
C 003 01 1
Here is what I want
ID Code tot_grp num_cand
A 001 4 3
A 002 4 1
A 003 4 1
B 001 3 3
B 002 3 1
C 002 2 2
C 003 2 1
where tot_grp is the total number of groups for each ID
and num_cand is the total number of candidates for each ID with that specific
code
Can I do it in one sql statement ?
Thank you

Answer 1

you said
where tot_grp is the total number of groups for each ID
and num_cand is the total number of candidates for each ID with that specific
code
Can u be more specific what should be present in tot_grp column.
Is it contains
a)sum of group for a given ID & code combination.
If yes then sql would be
select id,code,sum(group) tot_grp,count(cand) num_cand
from <table_name>
group by id,code
having the output ID Code tot_grp num_cand
A 001 5 3
A 002 1 1
A 003 1 1
B 001 4 3
B 002 1 1
C 002 2 2
C 003 1 1
2) Total No of groups(only the count) for a given Id & code
If yes then sql would be
select id,code,count(group) tot_grp,count(cand) num_cand
from <table_name>
group by id,code
having the output ID Code tot_grp num_cand
A 001 3 3
A 002 1 1
A 003 1 1
B 001 3 3
B 002 1 1
C 002 2 2
C 003 1 1
If none of the above condition is correct can u please be more clear .
