授予哪些权限以便从所有PDB中进行选择

Question

为什么两个选择都不会返回相同的结果？ 或者，如果您想要更一般的问题 - 为了从所有PDB中进行选择而授予哪些特权。

conn / as sysdba

create user c##nir identified by c##nir container=all;

grant connect,dba,resource to c##nir container=all;
grant select on cdb_synonyms to c##nir container=all;

select CON_ID  from cdb_synonyms  group by CON_ID;

Answer 1

答案：

ALTER USER c##nir set **container_data=all** container = current;

CONTAINER_DATA控制将从中查看的数据。
