使用外键删除 table

Question

我正在尝试此代码

Drop Table Inventory

我收到错误：

Could not drop object 'Inventory' because it is referenced by a FOREIGN KEY constraint.

Answer 1

使用这个

DROP TABLE Inventory CASCADE CONSTRAINTS;

Answer 2

首先你必须 Drop table 的约束，然后 table

SELECT 
    'ALTER TABLE ' +  OBJECT_SCHEMA_NAME(parent_object_id) +
    '.[' + OBJECT_NAME(parent_object_id) + 
    '] DROP CONSTRAINT ' + name
FROM sys.foreign_keys
WHERE referenced_object_id = object_id('Inventory')
Drop Table Inventory

Answer 3

您需要先删除约束..

ALTER TABLE [dbo].[t2] DROP CONSTRAINT [foreign key constraint]

然后你可以删除 table

Drop table t1

Answer 4

试试这个

ALTER TABLE Inventory NOCHECK CONSTRAINT all
DROP TABLE Inventory

Answer 5

从子 table 中删除外键约束，然后删除主 table

使用外键删除 table

Drop table with foreign key
