28.3.46 INFORMATION_SCHEMA USER_PRIVILEGES 表28.3.46 The INFORMATION_SCHEMA USER_PRIVILEGES Table

USER_PRIVILEGES 表提供有关全局权限的信息。它的值来自 mysql.user 系统表。The USER_PRIVILEGES table provides information about global privileges. It takes its values from the mysql.user system table.

USER_PRIVILEGES 表包含以下列：The USER_PRIVILEGES table has these columns:

GRANTEE
授予权限的账户名称，格式为 'user_name'@'host_name'。The name of the account to which the privilege is granted, in 'user_name'@'host_name' format.
TABLE_CATALOG
目录的名称。此值始终为 def。The name of the catalog. This value is always def.
PRIVILEGE_TYPE
授予的权限。该值可以是任何可以在全局级别授予的权限；参见第 15.7.1.6 节，“GRANT 语句”。每行列出单个权限，因此每个受赠者拥有的全局权限对应一行。The privilege granted. The value can be any privilege that can be granted at the global level; see Section 15.7.1.6, “GRANT Statement”. Each row lists a single privilege, so there is one row per global privilege held by the grantee.
IS_GRANTABLE
YES 如果用户拥有 GRANT OPTION 权限，否则为 NO。输出不会将 GRANT OPTION 显示为单独的行，且 PRIVILEGE_TYPE='GRANT OPTION'。YES if the user has the GRANT OPTION privilege, NO otherwise. The output does not list GRANT OPTION as a separate row with PRIVILEGE_TYPE='GRANT OPTION'.

注释Notes

USER_PRIVILEGES 是一个非标准的 INFORMATION_SCHEMA 表。USER_PRIVILEGES is a nonstandard INFORMATION_SCHEMA table.

下面的语句不等效：The following statements are not equivalent:

SELECT ... FROM INFORMATION_SCHEMA.USER_PRIVILEGES

SHOW GRANTS ...
