In Database I've Two Date Fields
Date1 & Date2

In my Query Parameters I've again Two Dates say d1 & d2
I've to check if the same dates are exists in Table
OR
If D1 or D2 is in between dates of Date1 and Date2
Example

Date1=01/01/2010
Date2=05/01/2010

If D1=01/01/2010
D2=05/01/2010

Return False

If D1=02/01/2010
D2=10/01/2010

Return False

If D1=30/12/2009
D2=03/01/2010

Return False

If D1=06/01/2009
D2=12/01/2010

Return True

Actually I'm uploading data between two dates. Someone should not upload duplicate data.
