Question

We’re using SQL Server 2005 and wanted to append two integers into another one. Right now we’re summing the month and year of a date field, which isn’t really what we want. Instead, we’d like to append them together, but retain an integer.

Here’s what we have right now:

SELECT 
       YEAR( MeetingDate) + MONTH( MeetingDate) AS DateGroup

We’d like DateGroup to read 20118, 20119, 201110, 201111 etc. Trying to learn some good ways of doing this.

Answer 1

Consider using a leading zero for one digit months, i.e. 201108 rather than 20118, then it’s easy:

select
   year(MeetingDate) * 100 + month(MeetingDate) as DateGroup

Otherwise you have to treat some months differently:

select
   year(MeetingDate) * case when month(MeetingDate) < 10 then 10 else 100 end
   + month(MeetingDate) as DateGroup
