Hi,
I have a date/time field in a SQL2000 database, and what I would like
to do is to filter on a specific part of the field, for example the
time or hour.
Supposing I have a set of data for the last 5 years and would like to
filter out any records which are outside working hours i.e. I would
like to show records where the time is between 9am and 5pm.
Does anyone know if there is a simple way to do this in SQL? If you
simply don't specify the date part in the where clause (e.g. WHERE
issuedatetime between '09:00:00' and '17:00:00') it defaults it to
1900-01-01 so basically no data is returned.
The only way I can see to do this is by using the DATEPART function,
converting it to a varchar, appending 1900-01-01 on to it and
converting it to a datetime, and then using the where clause as stated
above. This is quite a long-winded way, however. Any other suggestions?
Thanks,
Matt 3 14175
select * from TableName where datepart(hh,Col umnName) between 9 and 17

Look at the datepart function:
SELECT DATEPART(year,g etdate()),
DATEPART(quarte r,getdate()),
DATEPART(month, getdate()),
DATEPART(week,g etdate()),
DATEPART(weekda y,getdate()),
DATEPART(day,ge tdate()),
DATEPART(dayofy ear,getdate()),
DATEPART(hour,g etdate()),
DATEPART(minute ,getdate()),
DATEPART(second ,getdate()),
DATEPART(millis econd,getdate() )
It is also worth becoming familiar with DATEADD() and DATENAME().

Is there a way of making a Date/time field in a table a "null value"?
I would like to have "long time" as a null value.
05/12/2010 12:38:31 PM.
Reason - to add up all the fields with "null values" in a query.
In simple queries Nz works, but it becomes complicated after that.
If you use "0" as a default value in a number or text field it stays "0".
