Check Datetime Existence within multiple columns

  • [font="Courier New"]Hi there,

    I've a BillDate as date, and a Mark as bit column in First table.

    (Mark=0 by default)

    In Second table I've FromDate as date, and ToDate as date Column.

    I want to set Mark=1 if BillDate is exists between FromDate & ToDate

    Let Say In First Table the data is

    ----------------------------

    BillDate | Mark

    ----------------------------

    2012-11-10 11:15:30 | 0

    2012-12-12 09:00:00 | 0

    In Second Table the data is

    ---------------------------------------------

    FromDate | ToDate

    ---------------------------------------------

    2012-11-01 07:00:00 | 2012-11-09 23:59:59

    2012-12-08 07:00:00 | 2012-12-15 23:59:59

    So in the above scenario only the second row from First table

    which is having, BillDate->2012-12-12 09:00:00 will be Mark as 1

    because it comes between second row of second table

    I hope I've explained my scenario,[/font]
