Hi,

I'm having some problems interpreting the below code into an expression for a derived column. I'm trying to get the difference in minutes from when a purchase order was created (this would be the CreateTime in the code) and when the order was actually shipped indicated by POReleaseTime. Is it possible to convert this code to an expression? Does anyone have examples that could get me on track? Thanks in advance.

select DateDiff(n,
(CASE WHEN DATEPART(DW, PCR.CreateDate) IN (1,7) THEN '7:00:00 AM'
WHEN DATEDIFF(n,'4:59:00 PM',PCR.CreateTime)>0 THEN '7:00:00 AM'
WHEN DATEDIFF(n,'6:59:00 AM',PCR.CreateTime)<0 THEN '7:00:00 AM'
ELSE PCR.CreateTime END),PCR.POReleaseTime) AS pMinutes
 
This will give you the difference between the createddate and releasetime in minutes (assuming that both fields are datetimes?)

Code:
DATEDIFF(MI,PCR.CreateDate,PCR.POReleaseTime)

I feel sorry for people who don't drink, when they wake up in the morning that's as good as the're going to feel all day!
