您如何列出所有表格及其外文+；SQL查询中的主键？

有什么想法吗

这就是你要找的吗

USE Database
GO

SELECT * FROM sys.tables 
WHERE type = 'PK' AND parent_object_id = OBJECT_ID ('sys.tables')
GO

---

列出所有表和主键索引（如果存在）以及任何外键（以及FK引用的其他表）

那么，问题是什么？

SELECT
    TableName = t.Name,
    IndexName = I.Name,
    FKName = fk.Name,
    ReferencedTable = refT.Name
FROM 
    sys.tables t
LEFT OUTER JOIN 
    sys.indexes i ON i.object_id = t.object_id AND i.is_primary_key = 1
LEFT OUTER JOIN 
    sys.foreign_keys fk ON fk.parent_object_id = t.object_id
LEFT OUTER JOIN 
    sys.tables refT ON fk.referenced_object_id = refT.object_id
ORDER BY
    t.Name, i.Name
