Get the records of last month in SQL server

Question

I want to get the records of last month based on my db table [member] field "date_created".

What's the sql to do this?

For clarification, last month - 1/8/2009 to 31/8/2009

If today is 3/1/2010, I'll need to get the records of 1/12/2009 to 31/12/2009.

Answer 1

I'm from Oracle env and I would do it like this in Oracle:

select * from table
where trunc(somedatefield, 'MONTH') =
trunc(sysdate -INTERVAL '0-1' YEAR TO MONTH, 'MONTH')

Idea: I'm running a scheduled report of previous month (from day 1 to the last day of the month, not windowed). This could be index unfriendly, but Oracle has fast date handling anyways. Is there a similar simple and short way in MS SQL? The answer comparing year and month separately seems silly to Oracle folks.

Answer 2

WHERE 
    date_created >= DATEADD(MONTH, DATEDIFF(MONTH, 31, CURRENT_TIMESTAMP), 0)
    AND date_created < DATEADD(MONTH, DATEDIFF(MONTH, 0, CURRENT_TIMESTAMP), 0)

Answer 3

If you are looking for previous month data:

date(date_created)>=date_sub(date_format(curdate(),"%Y-%m-01"),interval 1 month) and 
date(date_created)<=date_sub(date_format(curdate(),'%Y-%m-01'),interval 1 day)

This will also work when the year changes. It will also work on MySQL.

One way to do it is using the DATEPART function:

select field1, field2, fieldN from TABLE where DATEPART(month, date_created) = 4 
and DATEPART(year, date_created) = 2009

will return all dates in april. For last month (ie, previous to current month) you can use GETDATE and DATEADD as well:

select field1, field2, fieldN from TABLE where DATEPART(month, date_created) 
= (DATEPART(month, GETDATE()) - 1) and 
DATEPART(year, date_created) = DATEPART(year, DATEADD(m, -1, GETDATE()))

Answer 5

SQL query to get record of the present month only

SELECT * FROM CUSTOMER
WHERE MONTH(DATE) = MONTH(CURRENT_TIMESTAMP) AND YEAR(DATE) = YEAR(CURRENT_TIMESTAMP);

Answer 6

select * from [member] where DatePart("m", date_created) = DatePart("m", DateAdd("m", -1, getdate())) AND DatePart("yyyy", date_created) = DatePart("yyyy", DateAdd("m", -1, getdate()))
