[sql-server] How do I exclude Weekend days in a SQL Server query?

How do I exclude values in a DateTime column that are Saturdays or Sundays?

For example, given the following data:

date_created
'2009-11-26 09:00:00'  -- Thursday
'2009-11-27 09:00:00'  -- Friday
'2009-11-28 09:00:00'  -- Saturday
'2009-11-29 09:00:00'  -- Sunday
'2009-11-30 09:00:00'  -- Monday

this is the result I'm looking for:

date_created
'2009-11-26 09:00:00'  -- Thursday
'2009-11-27 09:00:00'  -- Friday
'2009-11-30 09:00:00'  -- Monday

Thanks!

Calculate Leave working days in a table column as a default value--updated

If you are using SQL here is the query which can help you: http://gallery.technet.microsoft.com/Calculate...

Try the DATENAME() function:

select [date_created]
from table
where DATENAME(WEEKDAY, [date_created]) <> 'Saturday'
  and DATENAME(WEEKDAY, [date_created]) <> 'Sunday'

Assuming you're using SQL Server, use DATEPART with dw:

SELECT date_created
FROM your_table
WHERE DATEPART(dw, date_created) NOT IN (1, 7);

EDIT: I should point out that the actual numeric value returned by DATEPART(dw) is determined by the value set by using SET DATEFIRST:
http://msdn.microsoft.com/en-us/library/ms181598.aspx

Try this code

select (DATEDIFF(DD,'2014-08-01','2014-08-14')+1)- (DATEDIFF(WK,'2014-08-01','2014-08-14')* 2)

SELECT date_created
FROM your_table
WHERE DATENAME(dw, date_created) NOT IN ('Saturday', 'Sunday')

The answer depends on your server's week-start set up, so it's either

SELECT [date_created] FROM table WHERE DATEPART(w,[date_created]) NOT IN (7,1)

if Sunday is the first day of the week for your server

or

SELECT [date_created] FROM table WHERE DATEPART(w,[date_created]) NOT IN (6,7)

if Monday is the first day of the week for your server
