This script changes ownership for all tables, views, sequences and functions in
|
||
|
|
a database schema and also owner of the schema itself.
|
||
|
|
|
||
|
|
Note: If you want to change the ownership of all objects, in the specified database,
|
||
|
|
owned by a database role, then you can simply use command "REASSIGN OWNED".
