Answer 1

在您的查询中，您还没有为任何表定义名为 adm 的别名，我认为这就是问题，要么根据您的要求将其设为ab。*或urm。*或rpm。*期望的结果。

SELECT adm.*
  FROM adm_bucket ab
 INNER JOIN lms_user_role_mapping urm ON urm.bucket_id = ab.bucket_id
 INNER JOIN lms_roles_privilege_mapping rpm ON rpm.role_id = urm.role_id
 WHERE urm.user_id =19375 
   AND ab.bucket_OWNER=19375;
