本文主要是介绍information_schema系统表——COLUMN_PRIVILEGES，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
该表提供了有关列权限信息，这些信息来自mysql.columns_priv权限表
The COLUMN_PRIVILEGES table provides information about column privileges. This information comes from the mysql.columns_priv grant table.
INFORMATION_SCHEMA Name | SHOW Name | Remarks |
|---|---|---|
GRANTEE | ' value | |
TABLE_CATALOG | def | |
TABLE_SCHEMA | ||
TABLE_NAME | ||
COLUMN_NAME | ||
PRIVILEGE_TYPE | ||
IS_GRANTABLE |
Notes:
-
In the output from
SHOW FULL COLUMNS, the privileges are all in one field and in lowercase, for example,select,insert,update,references. InCOLUMN_PRIVILEGES, there is one privilege per row, in uppercase. -
PRIVILEGE_TYPEcan contain one (and only one) of these values:SELECT,INSERT,UPDATE,REFERENCES. -
If the user has
GRANT OPTIONprivilege,IS_GRANTABLEshould beYES. Otherwise,IS_GRANTABLEshould beNO. The output does not listGRANT OPTIONas a separate privilege.
