Error when converting datetime from character string

Question

I've googled this and plenty about this in the web but I am not sure why my string is not converting to datetime.

Any ideas?

SELECT gi.ITEM_NUM
,i.DSCR
 ,CAST(CASE WHEN (cast(MAX(CRTE_DTS) as datetime)) > DATEADD(d,-7,GETDATE()) THEN 1 ELSE 0 END  AS BIT) AS RECENT_ADD
FROM DAMART.dbo.T_x_ITEM AS gi
INNER JOIN DB.dbo.T_ITEM AS i
ON i.ITEM_NUM = gi.ITEM_NUM

Is that the only row in the table?

If not, it's quite likely there is at least one non-date string value stored in the CRTE_DTS column.

Try this to search for offending values:

SELECT CRTE_DTS 
FROM DAMART.dbo.T_x_ITEM AS gi
INNER JOIN DB.dbo.T_ITEM AS i
ON i.ITEM_NUM = gi.ITEM_NUM 
WHERE ISDATE(CRTE_DTS) = 0

How is the date represented in the database?

What's the result of just running "SELECT MAX(CRTE_DTS) FROM... (wherever)"

I've just tried the following, and it's worked quite happily, so I'm reckoning there might be some extra data that's floating to the top of the "MAX" calculation...

DECLARE @t VARCHAR(20)
SELECT @t = 'Oct 4 2007 2:41PM'
SELECT cast(@t as datetime)

... either that, or you've got some strange localisation settings.
