Oracle user permissions to grant tables:
- Syntax: grant [permission name (select | insert | update | delete | all)] on [table name] to [User Name]
- Example: user1 delegated authority to the query table1:
grant select on table1 to user1;
However, above a little trouble, if the table a lot, then perhaps you can use the cursor test, if the user table privileges are not very strict, authorized users can query table permissions for all users:grant select any table to gd_user with admin option;
However, when a query, or to add a user to query name, for example:select * from user.table1
The above is by way sql assign permissions, can also be authorized by the role, give the role permissions, then give users assign roles
Oracle system main roles:
- DBA: Has full privileges, is the highest authority, only the DBA can create a database structure.
- RESOURCE: Users with Resource privilege can only create an entity, can not create the database structure .
CONNECT: Connect Users with permission can only log Oracle, can not create an entity, can not create the database structure.
- Ordinary users: general grant connect, resource permissions.
DBA to manage user: grant connect, resource, dba privileges.
Sometimes the direct authorization of Oracle system roles, you can also create your own role, then authorize
By setting PLSQL
