Hi,
"Group by" is what you're looking for..
select type,sum(value) from MyTable group by type
Or for the total only
Select sum(case when type='C' then value when type='W' then -value else
0 end) from MyTable

Hi list,
I would like a little help from you to get the sum value of various
subsets of my table.
My table is like this
id | type | value
1 C 10.00
2 C 15.00
3 W 5.00
4 W 3.00
Where C is credit and w is witdraw.
How do I sum all records with C and subtract with all records with type
W ?
Is it possible ?
Ezequias
