This is my statement and it runs when I dont use the temp tables but why cant I use the same temp table in each statement. It should just skip the query if it doesnt match the criteria.

quote:
Declare @Date datetime
Set @Date = (SELECT DATEADD(DD,-7,max(dte))MDATE
From smb.dbo.vw_p_date_ref
Where FISCAL_MNTH = Case When CASE WHEN Day(getdate()) < 23 then MONTH(getdate()-DAY(getdate()))+1 Else Month(getdate())+1 End = 13 then 1 else CASE WHEN Day(getdate()) < 23 then MONTH(getdate()-DAY(getdate()))+1 Else Month(getdate())+1 End End
And FISCAL_YR = Case when MONTH(getdate()) = 12 and DAY(getdate()) > 21 then YEAR(getdate())+1 else YEAR(getdate()) End
)
IF GETDATE()< @Date

Begin

Select *
Into #Dates
From smb.dbo.vw_p_date_ref
Where FISCAL_MNTH = (Select FISCAL_MNTH
From smb.dbo.vw_p_date_ref
Where DTE = CASE WHEN DAY(GETDATE()) = 22 then cast(CAST(GETDATE()-1 as varchar(12)) AS DATETIME) else cast(CAST(GETDATE() as varchar(12)) AS DATETIME)End
)
And FISCAL_YR = (Select FISCAL_YR
From smb.dbo.vw_p_date_ref
Where DTE = CASE WHEN DAY(GETDATE()) = 22 then cast(CAST(GETDATE()-1 as varchar(12)) AS DATETIME) else cast(CAST(GETDATE() as varchar(12)) AS DATETIME)End
)
End
Else

Begin
Select *
Into #Dates
From
(
Select *
From smb.dbo.vw_p_date_ref
Where FISCAL_MNTH = (Select FISCAL_MNTH
From smb.dbo.vw_p_date_ref
Where DTE = CASE WHEN DAY(GETDATE()) = 22 then cast(CAST(GETDATE()-1 as varchar(12)) AS DATETIME) else cast(CAST(GETDATE() as varchar(12)) AS DATETIME)End
)
And FISCAL_YR = (Select FISCAL_YR
From smb.dbo.vw_p_date_ref
Where DTE = CASE WHEN DAY(GETDATE()) = 22 then cast(CAST(GETDATE()-1 as varchar(12)) AS DATETIME) else cast(CAST(GETDATE() as varchar(12)) AS DATETIME)End
)

Union All

Select top 7 *
From smb.dbo.vw_p_date_ref
Where FISCAL_MNTH = (Select FISCAL_MNTH
From smb.dbo.vw_p_date_ref
Where DTE = CASE WHEN DAY(GETDATE()) = 22 then cast(CAST(GETDATE()-1 as varchar(12)) AS DATETIME) else cast(CAST(GETDATE() as varchar(12)) AS DATETIME)End
)+1
And FISCAL_YR = (Select FISCAL_YR
From smb.dbo.vw_p_date_ref
Where DTE = CASE WHEN DAY(GETDATE()) = 22 then cast(CAST(GETDATE()-1 as varchar(12)) AS DATETIME) else cast(CAST(GETDATE() as varchar(12)) AS DATETIME)End
)
)ttTemp
End

Because
SELECT * INTO TABLENAME FROM ...
creates a new table.

The next statement will then also create a new table but it already exists created by the first statement.
