使用REFERENCED_TABLE_NAME并不总是有效，它可以是一个NULL值。下面的查询可以代替:

select * from INFORMATION_SCHEMA.KEY_COLUMN_USAGE where TABLE_NAME = '<table>';

对于表格:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>';

对于列:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>' AND
  REFERENCED_COLUMN_NAME = '<column>';

基本上，我们用where子句中的REFERENCED_COLUMN_NAME更改了REFERENCED_TABLE_NAME。

查找包含特定外键(如employee_id)的所有表

SELECT DISTINCT TABLE_NAME 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME IN ('employee_id')
AND TABLE_SCHEMA='table_name';

作为Node的替代答案，如果你使用InnoDB并定义了FK，你可以查询information_schema数据库，例如:

SELECT CONSTRAINT_NAME, TABLE_NAME, REFERENCED_TABLE_NAME
FROM information_schema.REFERENTIAL_CONSTRAINTS
WHERE CONSTRAINT_SCHEMA = '<schema>'
AND TABLE_NAME = '<table>'

对于<表>中的外键，或

SELECT CONSTRAINT_NAME, TABLE_NAME, REFERENCED_TABLE_NAME
FROM information_schema.REFERENTIAL_CONSTRAINTS
WHERE CONSTRAINT_SCHEMA = '<schema>'
AND REFERENCED_TABLE_NAME = '<table>'

对于<表>的外键

如果需要，还可以获得UPDATE_RULE和DELETE_RULE。

我不愿意再添加另一个答案，但我必须从其他人那里乞求、借用和窃取才能得到我想要的答案，这是给定模式中表上所有FK关系的完整列表，包括其他模式中表的FK关系。两个关键的记录集是information_schema。KEY_COLUMN_USAGE和information_schema.referential_constraints。如果缺少您想要的属性，只需取消KCU的注释。RC。看看有什么空房

SELECT DISTINCT KCU.TABLE_NAME, KCU.COLUMN_NAME, REFERENCED_TABLE_SCHEMA, KCU.REFERENCED_TABLE_NAME, KCU.REFERENCED_COLUMN_NAME, UPDATE_RULE, DELETE_RULE #, KCU.*, RC.*
FROM information_schema.KEY_COLUMN_USAGE KCU
INNER JOIN information_schema.referential_constraints RC ON KCU.CONSTRAINT_NAME = RC.CONSTRAINT_NAME
WHERE TABLE_SCHEMA = (your schema name)
AND KCU.REFERENCED_TABLE_NAME IS NOT NULL
ORDER BY KCU.TABLE_NAME, KCU.COLUMN_NAME;

我提出的解决方案是脆弱的;它依赖于django的外键命名约定。

USE information_schema;
tee mysql_output
SELECT * FROM TABLE_CONSTRAINTS WHERE CONSTRAINT_TYPE = 'FOREIGN KEY' AND TABLE_SCHEMA = 'database_name';
notee

然后在壳层中，

grep 'refs_tablename_id' mysql_output
