Set variable error
Posted on 2012-12-28
I have the following in a stored procedure
(Trying to capture value in a variable so can read it from a vb.net app)
DECLARE @TableTierCreditsMonth1 as Decimal(18,2)
DECLARE @TableTierCreditsMonth2 as Decimal(18,2)
DECLARE @TableTierCreditsMonth3 as Decimal(18,2)
;WITH TempTableTierCreditsMonth1
AS
(SELECT PlayerID
,sum(Table_TheoWin) AS TableTheoMonth1
,sum(Table_Win) AS TablewinMonth1
,case when sum(Table_TheoWin) >= sum(Table_Win) * @TableTierMultiplier then sum(Table_TheoWin) else sum(Table_Win) * @TableTierMultiplier end TableTierCreditsMonth1
FROM CopyPlayerManagement..Play
WHERE AccountingDate BETWEEN @BeginDateMonth1
AND @endDateMonth1
AND Table_Games > 0
and playerid = @PlayerID
GROUP BY PlayerID)
set @TableTierCreditsMonth1 = (Select TableTierCreditsMonth1 from TempTableTierCreditsMonth1
I get an error saying Incorrect syntax near the keyword 'SET'
Not sure why

You have to have a SELECT statement after a CTE:
SELECT @TableTierCreditsMonth1 = TableTierCreditsMonth1 from TempTableTierCreditsMonth1
SELECT @TableTierCreditsMonth1 = TableTierCreditsMonth1 from TempTableTierCreditsMonth1
I agree with above comment, the SET alone won't work, as it "forgot" the CTE already.
this will work better:

,sum(Table_TheoWin) AS TableTheoMonth1
,sum(Table_Win) AS TablewinMonth1
,case when sum(Table_TheoWin) >= sum(Table_Win) * @TableTierMultiplier then sum(Table_TheoWin) else sum(Table_Win) * @TableTierMultiplier end TableTierCreditsMonth1
FROM CopyPlayerManagement..PlayerDay
WHERE AccountingDate BETWEEN @BeginDateMonth1
AND @endDateMonth1
AND Table_Games > 0
and playerid = @PlayerID
GROUP BY PlayerID)
SELECT @TableTierCreditsMonth1 = TableTierCreditsMonth1
from TempTableTierCreditsMonth1
works fine if I use
SELECT @TableTierCreditsMonth1 = TableTierCreditsMonth1 from TempTableTierCreditsMonth1
But I wanted to capture another variable as well so I added
another select and it tells me the second one is invalid
can I only do 1?
SELECT @TableTierCreditsMonth1 = TableTierCreditsMonth1 from TempTableTierCreditsMonth1

it must be in the same select:
again: the "CTE" is only part of the select, it's not "defined" to be reused by as many statements later as "needed".
Scott: I posted the full code just trying to make clear that one cannot reuse the CTE for several statements... the CTE expression is part of the statement ...
DECLARE @TableTierCreditsMonth1 as Decimal(18,2)
DECLARE @TableTierCreditsMonth2 as Decimal(18,2)
DECLARE @TableTierCreditsMonth3 as Decimal(18,2)
;WITH TempTableTierCreditsMonth1 (Playerid,TableTheoMonth1, TablewinMonth1, TableTierCreditsMonth1)
AS
(SELECT PlayerID
,sum(Table_TheoWin) AS TableTheoMonth1
,sum(Table_Win) AS TablewinMonth1
,case when sum(Table_TheoWin) >= sum(Table_Win) * @TableTierMultiplier then sum(Table_TheoWin) else sum(Table_Win) * @TableTierMultiplier end TableTierCreditsMonth1
FROM CopyPlayerManagement..PlayerDay
WHERE AccountingDate BETWEEN @BeginDateMonth1
AND @endDateMonth1
AND Table_Games > 0
and playerid = @PlayerID
GROUP BY PlayerID)
SELECT @TableTierCreditsMonth1 = TableTierCreditsMonth1
, @TableTierCreditsMonth2 = TableTierCreditsMonth2
from TempTableTierCreditsMonth1
