sql server - Query to loop through a column and calculate totals for each unique record -


this might better done script, hoping can done query.

i have table called ledger. looks (simplified):

patid  amount   100    2500 100    1700 100    700 110    500 110    -75 120    350

can query @ table , return single line each patid correct total based on amount field?

in case, want report:

patid  amount 100     4900 110     425 120     350

thanks!

you can try using simple group by sum this,

 select        patid,       sum(amount) amount         yourtable  group        patid
