Hi

We have the value 'inv' for in a table to signify an Invoice transaction. I need to count how many time this value appears within a certain date criteria, it works but returns very wild numbers.

Code is:

SUM(CASE WHEN st_trantype IN ('inv') THEN 1 ELSE 0 END) AS Doc_Count

Sum distinct doesn't appear to be any good

All help appriciated

YOU can use count function instead of sum.
count(st_trantype) where st_trantype = 'inv'

use:

select count(*) from Table where st_transtype in ('inv')

query will be faster and you should get OK results :)
