use 'between' with varchar (sql server)

Question

Using SQL Server 2005 Express.

(
    CONVERT(VARCHAR(8), R.reviewStart, 108) between CONVERT(VARCHAR(8), M.meetingStart, 108) and CONVERT(VARCHAR(8), M.meeti         


        

Answer 1

Your first condition is equivalent to this more index friendly one:

R.reviewStart >=  DATEADD(day, DATEDIFF(day, '19010101', M.meetingStart), '19010101') 
and R.reviewStart < DATEADD(day, 1+DATEDIFF(day, '19010101', M.meetingStart), '19010101')
