I've existing DB called A. I created another DB called B from the backup of A.

I do modification in both databases. Say for example, in database A, in tableA a new column has been added. In database B, in tableA a column has been dropped.

I would like to know the schema changes. How to identify them? Is there any FREE tool existing for that? Or any other way existing to identify this? Or If I want to implement new tool what approach I've to follow?

Please do guide me.

Do you want to keep both the databases same all the time or you just want to know the changes? if you want to keep both the databases same you can try replication available in sqlserver.

Not in same time. A database in used in my application version 1.0 and B database is used in application version 2.0.

Note: I'm using SQL SERVER 2008 R2.

Once I know the difference, I need to upgrade the schema from lower version to higher version (means a common database which works in my application version 2.0). I know already database B works for application version 2.0. But I would like to incorporate the changes done in database A as well. So that I no need to maintain two databases.

Found sqlcompare is useful. It is commercial one. Any such kind of free tool available? If not, I would like to create my own tool. Please guide me how to achieve that?
