Dear I have table called Mst_Crew.
Fields are
Cr_No numeric
Cr_Name varchar
FromDate date
ToDate   date
I need to change the FromDate & ToDate when the ToDate pass the currentdate then need to be add 14Days on FromDate
For Example
CrNo	CrewName	FromDate	ToDate
1	A	29-Nov-15	13-Dec-15
2	B	06-Dec-15	20-Dec-15
3	C	13-Dec-15	27-Dec-15
4	D	22-Nov-15	06-Dec-15
The Next Change will be
CrNo	CrewName	FromDate	ToDate
1	A	27-Dec-15	10-Jan-16
2	B	03-Jan-16	17-Jan-16
3	C	10-Jan-16	24-Jan-16
4	D	20-Dec-15	03-Jan-16
It means that.
When Todate<GetDate() then in FromDate Column ToDate+14 and in ToDate Column FromDate+14
How to do this in SQL
Thanks
Basit.
