In Oracle, you can use the SHOW GRANTS statement to display the privileges granted to a specific user or role on a table. This statement provides a comprehensive view of the permissions associated with a table.
To retrieve the grants on a table, you can execute the following SQL statement:
SELECT *
FROM USER_TAB_PRIVS
WHERE TABLE_NAME = '<table_name>';
Replace <table_name>
with the actual name of the table you want to retrieve grants for. This query will return a result set containing the privileges granted to the current user on the specified table.
Here's an example to illustrate the usage of the SHOW GRANTS
statement in Oracle:
SHOW GRANTS ON employees;
This query will display the grants for the table named "employees" in the default output format.
You can also get the grants for a specific user or role using the following SQL statement:
SELECT *
FROM USER_TAB_PRIVS
WHERE GRANTEE = '<user_or_role_name>'
AND TABLE_NAME = '<table_name>';
Replace <user_or_role_name>
with the name of the user or role you want to retrieve grants for. This query will return the grants for the specified user or role on the specified table.
In summary, the SHOW GRANTS
statement in Oracle is a powerful tool for retrieving the privileges granted to a user or role on a table. It allows you to effectively manage access control and security in your database environment.
Note: The above SQL statements assume that you have appropriate privileges to execute them and access the necessary system views such as USER_TAB_PRIVS
.
