In the code below, I'm getting Incorrect syntax errors on the first IF, the second FROM and the last parenthesis. I cannot see why. Is it that i can;t have embedded IF's. If that's the case, how would this be written legally? Thanks in advance!!


select * from [dbo].[OrderItem] o
where o.ORDERITEM_ID in 
(
IF @selectdate=null
BEGIN
select ORDERITEM_ID from [dbo].[OrderItem] where UPDATEDDATE is not null
END
						
IF @selectdate is not NULL
BEGIN
declare @tempdate datetime
select @tempdate = CAST(FLOOR( CAST( @selectdate AS FLOAT ) )AS DATETIME)
				
select ORDERITEM_ID from [dbo].[OrderItem] 
where @tempdate = CAST(FLOOR( CAST( CREATEDDATE AS FLOAT ) )AS DATETIME)
AND UPDATEDDATE is not null						
						END						
)

[code]
select * from [dbo].[OrderItem] o
where o.ORDERITEM_ID in

CASE WHEN @selectdate is not NULL THEN
(SELECT ORDERITEM_ID from [dbo].[OrderItem] WHERE UPDATEDDATE is not null
ELSE
SELECT ORDERITEM_ID from [dbo].[OrderItem]
WHERE CAST(FLOOR( CAST( CREATEDDATE AS FLOAT ) )AS DATETIME)
AND UPDATEDDATE is not null
END)

[/code]

I think?

[code]
select * from [dbo].[OrderItem] o
where o.ORDERITEM_ID in
(SELECT ORDERITEM_ID from [dbo].[OrderItem] WHERE UPDATEDDATE is not null
AND ((CREATEDDATE >DATEADD(dd,DATEDIFF(dd,0,@selectdate),0)
AND CREATEDDATE < DATEADD(dd,DATEDIFF(dd,0,@selectdate)+1,0))
OR @selectdate IS NULL)
[/code]

That was close, just need to clean it up. Thanks!!

This is it:

CASE WHEN @selectdate is NULL THEN
(SELECT ORDERITEM_ID from [dbo].[OrderItem] WHERE UPDATEDDATE is not null)
ELSE
(SELECT ORDERITEM_ID from [dbo].[OrderItem]
WHERE CAST(FLOOR( CAST( @selectdate AS FLOAT ) )AS DATETIME) = CAST(FLOOR( CAST( LOGDATE AS FLOAT ) )AS DATETIME)
AND UPDATEDDATE is not null)
