Code for 1st day & the Last day of the Previous Month

Hi there,

See if you can help me with the following:

I need to write an SQL code that will return me:

The 1st day & the Last day of the Previous Month in the following format
(smalldatetime):

yyyy-mm-dd hh:mi:ss (24h)

Regards,

situations like this), you can do it on-the-fly using SQL Server like
so:

SELECT DATEADD(m, -1, FirstOfCurrentMonth) as FirstOfPreviousMonth,
DATEADD(d, -1, FirstOfCurrentMonth) as LastOfPreviousMonth
FROM (SELECT CONVERT(smalldatetime,DATENAME(m, GetDate())
+ ' 1,' + DATENAME(yyyy, GETDATE())) as FirstOfCurrentMonth) a

Of course, you'll want to do the formatting on the client side.

HTH,

declare @.d1 smalldatetime
declare @.d2 smalldatetime
declare @.d3 smalldatetime

-- @.d1 is the input date
set @.d1 = CURRENT_TIMESTAMP
-- truncate hours, min, etc.
set @.d1 = convert(smalldatetime, floor(convert(float, @.d1)))

-- @.d2 - last day of previous month

set @.d2 = dateadd(day, - datepart(day, @.d1), @.d1)

-- @.d3 - first day of previous month

set @.d3 = dateadd(day, - datepart(day, @.d2) + 1, @.d2)|||Hi Stu,

Thank you very very much .... it was a great help.

Best regards,

instead of trying to compute it on the fly. Next, the display of
temporal data has nothing to do how it is stored.|||Ross,

Thank you so much ...
