Question

I have a employee table with columns like

emp_id, firstname, lastname, month  and year.

Now I need to get employees from table between jan 2012 and march 2012.
In columns month and year we are storing “1” for jan and “3” for march i.e. month numbers and year column has year like 2012.
Please help.

Answer 1

Employees between Januar and March 2012:

select * from employee
where year = 2012 and month between 1 and 3

Employees between Januar 2012 and March 2013:

select * from employee
where (year = 2012 and month between 3 and 12)
or (year = 2013 and month between 1 and 3)
