MySQL 中的系统视图

Question

我正在使用系统目录视图（例如 SYS.ALL_ OBJECTS、SYS.FOREIGN_KEYS 等）来获取有关我在 MS SQL 2005 中的数据库结构的信息。

MySQL (v. 5) 服务器是否有等效的功能/视图？

Answer 1

对于模式（所有对象）；

SELECT * FROM information_schema.SCHEMATA S;

也适用于约束和外键；

SELECT * FROM information_schema.TABLE_CONSTRAINTS T;

对于其他所有内容，请检查此查询；

SELECT * FROM information_schema.CHARACTER_SETS C;
SELECT * FROM information_schema.COLLATION_CHARACTER_SET_APPLICABILITY C;
SELECT * FROM information_schema.COLLATIONS C;
SELECT * FROM information_schema.COLUMN_PRIVILEGES C;
SELECT * FROM information_schema.`COLUMNS` C;
SELECT * FROM information_schema.KEY_COLUMN_USAGE K;
SELECT * FROM information_schema.PROFILING P;
SELECT * FROM information_schema.ROUTINES R;
SELECT * FROM information_schema.SCHEMA_PRIVILEGES S;  
SELECT * FROM information_schema.STATISTICS S;
SELECT * FROM information_schema.TABLE_PRIVILEGES T;
SELECT * FROM information_schema.`TABLES` T;
SELECT * FROM information_schema.TRIGGERS T;
SELECT * FROM information_schema.USER_PRIVILEGES U;
SELECT * FROM information_schema.VIEWS V;
