sql-server - 设置 IDENTITY_INSERT ON 不起作用

Question

我想将表 Equipment 从一个数据库 MyDBQA 复制到我们的测试数据库 MyDB。表中有一个标识列，它是主键(int，不为空)。

但是我得到了一个错误:

Msg 8101, Level 16, State 1, Line 2
An explicit value for the identity column in table 'MyDB.dbo.Equipment' can only be specified when a column list is used and IDENTITY_INSERT is ON.

我的脚本:

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON
INSERT INTO [MyDB].[dbo].[Equipment]  SELECT * FROM [MyDBQA].[dbo].[Equipment]
SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF

Answer 1

正如消息所述，您可能只是缺少列列表

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON

INSERT INTO [MyDB].[dbo].[Equipment]
            (COL1,
             COL2)
SELECT COL1,
       COL2
FROM   [MyDBQA].[dbo].[Equipment]

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF
