For example:
The year end of company ABC is February. This is represented as a 2 in the database. The goal is to convert this to a date in the current year. So if it is 2011 then the aim is to generate the date, 2011-02-28. The next year the date should be 2011-02-28 etc.
The query:
select dateadd(day,-1, dateadd(month,1, convert(datetime,convert(char(4),year(getdate()))+'-'+convert(varchar,c.YEM)+'-'+'1'))) from (select 2 as YEM) c
Enjoy.
