Date Ranges Start and End ASE 12 T-SQL

— Getting month ranges

–First you need to figure out the current date:

declare @today datetime
select @today=getdate()
–Let’s start with the current month:

–Make the Assumption for examples I am working with a date of January, 30th. So the first day of the month is January, 1st.
–Unfortunately, you cannot directly set the day to 1. But you can extract the day from the date, in our case 30 and 1 is 30 – (30 – 1), so:

select dateadd(dd,-(day(@today)-1),@today)
–This will return: Jan 1 2013 1:49PM

–So basically we have the right date but for comparison purposes, we’d rather have midnight than 1:49pm.
–In order to do it, you need to convert it to a date string and back to a datetime:

select convert(datetime, convert(varchar(10),dateadd(dd,-(day(@today)-1),@today),101))
–Now we get: Jan 1 2013 12:00AM
–if you’re only interested in a string containing the date, just drop the outer convert:
select convert(varchar(10),dateadd(dd,-(day(@today)-1),@today),101)
–Use another format than 101 if needed. The complete list of date conversion formats can be found here. For example, for the German date format, use 104 (dd.mm.yyyy).

–MULTIPE PARTS HERE — Now let’s get the last day of the current month. This is basically the day before the first day of next month.

–So first let’s get the first day of next month.
— This is actually just 1 month later than the first day of the current month:

select convert(varchar(10),dateadd(mm,1,dateadd(dd,-(day(@today)-1),@today)),101) as ‘First day of next month.’ — Part one of last day of current month
–This returns: 02/01/2013

–Now let’s just substract one day and we’ll get the last day of the current month:

select convert(varchar(10),dateadd(dd,-1,dateadd(mm,1,dateadd(dd,-(day(@today)-1),@today))),101) as ‘last day of the current month’
–This returns: 01/31/2013

–Since we already have the first day of next month, let’s get the last day of next month.
— This is basically the same again but instead of adding 1 month, you add 2 months:

select convert(varchar(10),dateadd(mm,2,dateadd(dd,-day(@today),@today)),101) as ‘last day of next month’
–This returns: 02/28/2013

–Now let’s tackle the previous month.
— The first day of last month is basically the first day of the current month minus 1 month:

select convert(varchar(10),dateadd(mm,-1,dateadd(dd,-(day(@today)-1),@today)),101) as ‘first day of last month’
–This returns: 12/01/2012

–And then the last day of previous month. It is one day before the first day of the current month:
select convert(varchar(10),dateadd(dd,-(day(@today)),@today),101) as ‘last day of previous month’
–This returns: 12/31/2012

Powershell importing data from SQL into Excel COM OBJECT interop and EMAILING

I needed to pull data from a ASE Database (T-SQL), filter it and then dump it into a excel workbook.  Finally wrap all that up and attach it to a Email via SMTP…
