I'm not sure if the answer to this lies in the F_TABLE_DATE Function or not.
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=61519
I looked at the function, but I have NO idea what I'm looking at and what it does.
I have two dates a start date(@s_date) and end date(@e_date). I would like to know the number of working days that are between these two dates. I want to exclude Saturdays and Sundays and Some of the American Federal Holidays.
I say some because we are open and count some as working days and some not.
I can give some dates like New Years Day is always 1/1/???? but Thanksgiving is 11/??/????.
But in any case is my answer to finding the number of working days between two dates in the function above or is there something less complex that I may be able to grasp?

This would help u,
if there any issues let me know.
DECLARE @StartDate DATETIME,
@EndDate DATETIME
SELECT @StartDate = '01-July-2008',
@EndDate = '30-July-2008'
;WITH DATE (Date1)
AS (
SELECT DATEADD(DAY, DATEDIFF(DAY, '19000101', @StartDate), '19000101')
UNION ALL
SELECT DATEADD(DAY, 1, Date1)
FROM DATE
WHERE Date1 < @EndDate
)
SELECT
CONVERT(VARCHAR(15),d1.DATE1 ,110) as [Working Date],
DATENAME(weekday, d1.Date1) [Working Day]
from DATE d1 where (DATENAME(weekday, d1.Date1)) not in ('Saturday','Sunday') |

SELECT COUNT(*)
FROM F_TABLE_DATE(@s_date, @e_date) d
left JOIN holidays h ON d.[DATE] = h.[DATE]
WHERE h.[DATE] IS NULL
AND d.[DAY_OF_WEEK] BETWEEN 2 AND 6

Thanks VG for the quick reply.
I took what you had and posted it in my SQl analyer and the following error came up Incorrect syntax near the keyword 'WITH'.
I tried taking it out ; and replacing it with , but no luck.
I'm pretty new to this so if I;m overlooking the obvious excuse me.

That code is for SQL Server 2005. Are you using 2005 or 2000 ?

VGuyz solution will not work on SQL2000 as it uses a CTE

Thanks fior the reply KH.
I take it my answer is in the F_TABLE_DATE function?
Most of that TO ME is chinese.
Can I copy it and paste into my SQL analyzer, run it and it will work?

I found in excel there is a networkday function. =networkday(Date1, date2, holidays) and that worked fine for me in Excel. Does not work in SQL.

Hi cardgunner,
really sorry ya,
i have not think abt sql server 2005 or 2000
chk it out this query
SELECT CONVERT(VARCHAR(15),DATEADD(d,number,getdate()),110) as [Working Date],
DATENAME(weekday, DATEADD(d,number,getdate()))as [Working Day]
FROM master..spt_values
WHERE type='p'
AND DATEPART(dw,DATEADD(d,number,getdate())) NOT IN (1,7) |

It you can calculate the number of days, that would be better than counting the days.
Try thiscreate function workhours_jeff(@StartDate datetime, @EndDate datetime) returns float as
begin
return CAST(
(
(DATEDIFF(dd,@StartDate,@EndDate)+1)
-(DATEDIFF(wk,@StartDate,@EndDate)*2)
-(CASE WHEN DATENAME(dw,@StartDate) = 'Sunday' THEN 1 ELSE 0 END)
-(CASE WHEN DATENAME(dw,@EndDate) = 'Saturday' THEN 1 ELSE 0 END)
)
-(CASE WHEN DATENAME(dw,@StartDate) = 'Sunday' or DATENAME(dw,@StartDate) = 'Saturday' THEN 0
ELSE CAST(CONVERT(CHAR(12),@StartDate,114) AS DATETIME) END)
-(CASE WHEN DATENAME(dw,@EndDate) = 'Sunday' or DATENAME(dw,@EndDate) = 'Saturday' THEN 0
ELSE (1.0-CAST(CONVERT(CHAR(12),@EndDate,114) AS DATETIME)) END)
AS FLOAT) * 24
end
go
E 12°55'05.25"
N 56°04'39.16" |

Ok
I copied the code below and ran it. I got some errors
Server: Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'table'.
Also I need to declare @FIRST_DATE, @LAST_DATE, @start_date, @end_date, and @DATE
Server: Msg 208, Level 16, State 11, Line 2
Invalid object name 'dbo.F_TABLE_DATE'.
Please be patient I have no idea exactly what a function is and a little idea what it does but unsure how it does it.
Also I have very little idea of what I'm doing.
returns @DATE table

Sorry I didn't bring in the first part so I copied now from
if exists (select * from dbo.sysobjects
to
dbo.F_TABLE_DATE ( '20000101','20101231' )
order by 1
and I get the following errors:
Server: Msg 137, Level 15, State 2, Procedure F_TABLE_DATE, Line 472
Must declare the variable '@start_date'.
Server: Msg 137, Level 15, State 1, Procedure F_TABLE_DATE, Line 473
Must declare the variable '@end_date'.
Server: Msg 208, Level 16, State 11, Line 2
Invalid object name 'dbo.F_TABLE_DATE'.
Checksum with ydm

Wow!
Thanks KH(Khtan) for the nudge.
I changed @start_date and @end_date to @START_DATE and @END_DATE and everyhting ran.
I then took your select statement and added my info as below and it came up with 120 days which should be accurate.
declare @s_date datetime
declare @e_date datetime
select @s_date='2008-03-11 00:00:00.000'
select @e_date='2008-08-26 00:00:00.000'
SELECT COUNT(*)
FROM F_TABLE_DATE(@s_date, @e_date) d left JOIN
(select '2008-7-04 00:00:00.000' [DATE]
) h ON d.[DATE] = h.[DATE]
WHERE h.[DATE] IS NULL
AND d.[DAY_OF_WEEK] BETWEEN 2 AND 6
I know what I did to get it but I don't know what it all means.
I looked and there is only a new function in my db right?
This is really great! Thank you very much.

I hope that you realize that the guery against F_TABLE_DATE is only giving you a count of weekdays.
If you want to exclude holidays, you will need to create a table with the holidays, and join to the output from your query to exclude holidays.

Yup, that I got. I tested with just one date and it worked.
I may still have an issue cause I'm trying to find the number of working days from a datefield in a table to a set date. Where my results will be say 262 records long.
This works for two set dates @s_date and @e_date.
How do I do it for a 262 records?
