Create your database objects in one schema and grant SELECT on them to the other (read-only) schemas.

Yes, all the users with SELECT on the table will see the same data. However, note that they will not see uncommitted data.

the schema owner represents the Oracle user that owns all your database objects, while application users are Oracle users that need access to those schema objects.

Allowing applications to make direct connections to the schema owner is a bad idea because it gives those applications far to many privileges, which can easily result in damage to your data and the objects themselves and also i have create one columns in table.For these select privilages,it will not replicate in user(B).

Thanks,
Michael.

I'm not sure if you're making a statement or asking a question. However, if you need other schemas to only see certain columns, you will have to create views and then grant SELECT on those views.

Hi,

I have created synonyms for all tables and give select privilege to it.i able to select the data from other users.

Is any possible to select any tables from one user to other user?

I tried like this.

grant select,insert,update,delete any tables from usera to userb:

It shows a error like ORA-00990: missing or invalid privilege error.

Is it possible?

thanks,
Michael

You have to grant privilege for each table.

Remark: insert,update,delete are not read-only.

Michel

Just in case you didn't get the point:

grant select,insert,update,delete any tables from usera to userb:

any tables is wrong (if you really used that syntax) as you'll have to grant privileges for every single table in its own GRANT statement:

GRANT SELECT ON emp TO user_b;
GRANT SELECT ON dept TO user_b;
etc.

Of course, it might be painful if there are many tables; that's why you may write a SQL which will create these statements for you. If you are interested in such a solution, search the board - there've already been such questions (and answers).
