I have Production database and Test database environment for Oracle db.
In production I have script that update table tbl_A from tbl_B; tbl_C; tbl_D.
In test database I have the same script that update my tbl_A from tbl_B; tbl_C; tbl_D which have different data that production tables.
Now I would like to run the same sript in production to update my production tbl_A but from my test tables.
How to do that.
