And what problems are you having? Simply grant the appropriate rights to the appropriate users.

Machines don't code. People do.
So grant privs to people, not to machines.
I bet all your developers use the object owner's username to logon to the database, right?

You'll have to grant privileges on every table to every user separately. There's no way to grant privileges on a whole schema; of course, it doesn't mean that you'll have to write all these GRANT statements by yourself - write an SQL which will write SQL for you (there've been examples here before - search for them!).

Also, perhaps you'd want to create a ROLE which would be granted SELECT on these tables, and then you'd simply GRANT ROLE to all users.

So you are saying that you have multiple people, logging in as the same user. Baaaaaad idea!

Then you are, as a colleague of mine would say, "On to plums". Create a user for each user (see, the hint is in the term Wink ) Give each user the appropriate rights.

Pablolee is a native English speaker (really, what language do you speak in Scotland? Scotch ./fa/1602/0/?) so - just in case you can't understand that, let me try again, this time in Croatian English:

You work in a company. There is a Boss and four employees: Wilma, Fred, Betty and Barney. You have also decided to create a database; tables are stored in a schema and owned by user. Its name is ORACLE_TEST.

As Boss is THE boss, he knows password which is used to connect to the ORACLE_TEST schema and he can read, update and delete anything he wants.

However, the Boss and you agreed that the rest of the employees should only read (i.e. SELECT) data. You can not do that by giving them ORACLE_TEST's password and ask them not to modify anything they see (because, someone of the WILL change something, some day). Therefore, you'll have to do something else: create one database user per employee, for example: ORACLE_FRED, ORACLE_BARNEY, ORACLE_WILMA and ORACLE_BETTY.

You'd then grant some privileges to these users: SELECT and UPDATE to Barney and Betty, just SELECT to Fred and Wilma. You can do that by creating roles, grant privileges to these roles and - finally - grant roles to database users. Or, you can grant privileges directly to users - whichever you prefer.

You'll also create synonyms in their schemas which will point to the "original" ORACLE_TEST's tables.

Tomorrow morning, Fred will connect to the database as ORACLE_FRED/FREDDIE@MERCURY (or whatever your database alias is) and will be able to query records; any other action will be followed by the "insufficient privileges" error message.

That was one of many possible scenarios ./fa/2877/0/, but I hope you now got the picture.
