Hi,

Thank you for the reply, but if I know the role or group, I can easily get the details from above commands, but for a specific DB , if I want to  find out what are the roles assigned, is there a way to do it ? 

Assume, my schema name is schema1, how to find out the roles assigned to this schema ? 

Thank you.

PK,

If you have access to the Sentry Store backend use a query like this:

SELECT
r.ROLE_NAME,
g.GROUP_NAME,
p.*,
FROM_UNIXTIME(p.CREATE_TIME / 1000) as CREATE_TIME_DATE
FROM
SENTRY_ROLE r
INNER JOIN SENTRY_ROLE_GROUP_MAP rgm ON r.ROLE_ID = rgm.ROLE_ID
INNER JOIN SENTRY_GROUP g ON g.GROUP_ID = rgm.GROUP_ID
INNER JOIN SENTRY_ROLE_DB_PRIVILEGE_MAP rpm ON r.ROLE_ID = rpm.ROLE_ID
INNER JOIN SENTRY_DB_PRIVILEGE p ON p.DB_PRIVILEGE_ID = rpm.DB_PRIVILEGE_ID;

Hope it helps,
