i have a table
account number, date, type, amount
0000001, 20250815, P, 200.00
0000001, 20250810, C, -125.00
0000001, 20250801, C, -75.00
0000001, 20250725, C, -125.00
0000001, 20250720, P, 175.00
......
i need the query to stop when it finds the first P type after the first one. so i would get
0000001, 20250815, P, 200.00
0000001, 20250810, C, -125.00
0000001, 20250801, C, -75.00
0000001, 20250725, C, -125.00
and stop.

Define your sort order to determine "first"

the account, date is the sort order and and FYI the type field values can be C, D, A, L and O so in my example i just used C for in between the P types. What i am looking for is like a statement report for all accounts and i want to pull/report the entries from the payment to previous P.

Hmm, you may find the range with cross apply
Perhaps you can get lucky with windows functions
/*pseudocode as there is no copy paste sample data*/
with payments
(
select current.key currentpayment, previous.key previous payment
from mytable current where current.type=payment
cross apply (select top 1 key from mytable previous where previous.type = payment and previous.key<current.key order by previous.key desc) /* find the previous one*/
/* where current.key = ... */
)
select mytable...
from mytable inner join payments
where mytable.key<=payments.currentpayment and (mytable.key>payments.previouspayment or payments.payments.previouspayment is null

ORDER BY Account, TransDate DESC;

Thank you both, i am still learning/testing the cross apply but the sum over partition sample works for sure.
i am working on the final product being a stored procedure to run by account number and a starting date.
thank you both, i really appreciate the information
