As a programmer working with Oracle databases, you may encounter the need to grant permissions to users or roles to access specific data in a schema. The GRANT SELECT
command is used to provide read-only access to data in a specified schema.
GRANT SELECT ON schema_name.table_name TO user_name;
In this syntax, schema_name
refers to the schema containing the table you want to grant access to, table_name
is the name of the table to which you want to grant access, and user_name
is the user or role to which you want to grant access.
Suppose you want to grant a select permission on a table employees
in the schema hr
to the user johndoe
. You can use the following command:
GRANT SELECT ON hr.employees TO johndoe;
Instead of a user, you might want to grant permissions to a role. In that case, you can replace user_name
with role_name
in the syntax we saw earlier. Here's an example:
GRANT SELECT ON hr.departments TO hr_manager_role;
