Thank you for the Reply!.. my criteria is that we would have mutiple records (Start and EndDt's) in the @Table1 for single ID and also the same in the @table2. Your query pickup the records the correct records from @Table1 who's date are out of range. below is the data that i have. i would need the out from the @Table1 (ID,StartDt,EndDt) which dont fall in the range of the @table2.

Thank you once again for taking time to help me out.

StartDt datetime,

EndDt datetime)
