hi,


i have created database with the name juzz in sql server 2008 r2 and the table name is detals.

the table detail has 3 column(c1,c2,c3)

now i am taking backup of the database and used in client machine.

the client fills some values to the table..

now i am adding another two column in the table ie(c1,c2,c3,c4,c5)

now i want to merge the data from the client database to my new created table ie(c1,c2,c3,c4,c5).

Thanks Regards,
