如何在 sql 服务器中找到所有包含给定表主键外键的表？

Question

I am trying to search all the tables from database which contains foreign key of given(specific) table's primary key in sql server. Please help.

Answer 1

You can use this built-in stored procedure to search all foreign keys for the given table

EXEC sp_fkeys 'TableName'

If this doesn't suit your needs, you can try 10 other ways on this page - https://database.guide/11-ways-return-foreign-keys-sql-server-database-t-sql/

Answer 2

Try this..

SELECT
  sys.columns.name AS ColumnName,
  tables.name AS TableName
FROM
  sys.columns
JOIN sys.tables ON
  sys.columns.object_id = tables.object_id
WHERE
  sys.columns.name = 'ForeignKeyColumnName'

Answer 3

This should be a good starting point:

select object_name(parent_object_id)
from sys.foreign_keys
where referenced_object_id = object_id('ParentTable');

This doesn't take into account that the FK is specifically referencing your table's PK. If the above doesn't narrow it down enough, start pulling in sys.foreign_key_columns . I'll leave that as an exercise for the reader.
