How to call this function

I want to calculate 72 hours elapsed time but exclude the weekends. I found this function

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=61519&SearchTerms=F_TABLE_DATE.

I can call it directly like this:
 SELECT * FROM   F_TABLE_DATE('2012-12-07 10:55:25.220', GETDATE()) d
    WHERE
  d.[DAY_OF_WEEK] BETWEEN 2 AND 6

Open in new window


But not sure how to call it. This is my sql but doesnt work

SELECT *
 FROM dbo.NonMemberProvider
 WHERE officecalled IS NULL
 AND DATEDIFF(hour, UPDATEDate, GETDATE()) > 72	
 AND  ( SELECT * FROM F_TABLE_DATE(UPDATEDate, GETDATE()) 
        WHERE
  d.[DAY_OF_WEEK] BETWEEN 2 AND 6 )

Open in new window

-- here's something to try along the same line of thinking:

SELECT *
 FROM dbo.NonMemberProvider
 WHERE officecalled IS NULL
 AND DATEDIFF(hour, UPDATEDate, GETDATE()) > 72      
 AND  DATEPART( WEEKDAY, UPDATEDate ) between 2 and 6

it think you want to "CROSS APPLY" that table function:
SELECT t.*
 FROM dbo.NonMemberProvider t
  CROSS APPLY F_TABLE_DATE(t.UPDATEDate, GETDATE())  f
 WHERE t.officecalled IS NULL
 AND DATEDIFF(hour, t.UPDATEDate, GETDATE()) > 72	
 AND f.[DAY_OF_WEEK] BETWEEN 2 AND 6

Seems like knight is correct. Cross Apply one gives me repeated rows.
Anyway to exclude holidays?

Not unless you have a specific holiday or set of holidays in mind.  Certain holidays fall on different dates each year (for example, first Monday of the month), whereas others are always on the same day, in which case:

SELECT *
 FROM dbo.NonMemberProvider
 WHERE officecalled IS NULL
 AND DATEDIFF(hour, UPDATEDate, GETDATE()) > 72      
 AND  DATEPART( WEEKDAY, UPDATEDate ) between 2 and 6
AND NOT ( DATEPART(month,UPDATEDate)=12 and DATEPART(day,UPDATEDate)=25 )  -- excludes December 25

Should I create a Holiday table and join to that?

knightEknightCommented:
Yes, that could work... then you could excludes dates in that table:

SELECT *
 FROM dbo.NonMemberProvider T
 WHERE officecalled IS NULL
 AND DATEDIFF(hour, UPDATEDate, GETDATE()) > 72      
 AND  DATEPART( WEEKDAY, UPDATEDate ) between 2 and 6
 and UPDATEDate not in ( select holdate from HolidayTable )

knightEknightCommented:
actually, my last post assumes UPDATEDate is a date type(as opposed to a datetime).  If it is a datetime then you could cast it like this, but doing this will slow down your query considerably:

and cast(UPDATEDate as DATE) not in ( select holdate from HolidayTable )
