I have found a few posts that were very similar to what I am wanting to do, but it didn't seem to work. I have this case in my select:
case
when h.Posted_Flag=-1 and h.Returned_Flag=0 then 'Posted'
when h.Posted_Flag=0 then 'Unposted'
when h.Returned_Flag=1 and h.Posted_Flag=-1 then 'Returned'
when h.Returned_Flag = 2 then 'Partial Return'
else '*****'
end as Return_Status,
I would like to place this in my where clause and equal to a variable I have set:
Declare @TicketStatus nvarchar
set @TicketStatus = 'Returned'
and @TicketStatus=(case
when h.Posted_Flag=-1 and h.Returned_Flag=0 then 'Posted'
when h.Posted_Flag=0 then 'Unposted'
when h.Returned_Flag=1 and h.Posted_Flag=-1 then 'Returned'
when h.Returned_Flag = 2 then 'Partial Return'
end)
When I try to run what I have, I get no records returned, when I run this without the AND(case) there are many Retunred Status's with Returned in them.
any help would be great.
thanks BD
This is a problem with how you declared your variable. What happens if you do this?
Declare @TicketStatus nvarchar
set @TicketStatus = 'Returned'
SELECT @TicketStatus
The returned value is 'R'
, not 'Returned'
, this happens because you didn't give a length to your variable. You should do this:
Declare @TicketStatus nvarchar(15)
set @TicketStatus = 'Returned'
您为什么不只使用条件?
h.Returned_Flag=1 and h.Posted_Flag=-1
