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,

[code]
UPDATE t1
SET Mark=1
FROM table1 t1
JOIN table2 t2
ON t1.BillDate >= t2.FromDate
AND t1.BillDate <= t2.ToDate
[/code]
