Hi all,
When updating our ticket history, if I want to delete our single ticket constituency simply based upon not having purchased tickets in the last year would this be the correct way to achieve this?
Cheers!

IF @constituency is not null
delete a
from tx_const_cust a
where a.constituency = @constituency and
not exists (select * from lt_tkt_hist b
where a.customer_no = b.customer_no
and b.perf_dt > dateadd(year,-1,getdate()))
I have no idea where this came from
Ryan,
I'd set the end_dt in tx_const_cust to the current time instead of deleting the row.

something to consider but what I'm curious about in my lack of SQL skills is if this bit of code is the correct/best way to accomplish the minus 1 year logic.
b.perf_dt > dateadd(year,-1,getdate()))
Ah, sorry I mis-read.
It looks good by me, removing the constituency unless they have a performance within the last year.
