sql-server - 仅当使用列列表且 IDENTITY_INSERT 为 ON SQL Server 时，才能指定表中标识列的显式值

Question

我正在尝试执行此查询

INSERT INTO dbo.tbl_A_archive
  SELECT *
  FROM SERVER0031.DB.dbo.tbl_A

但即使在我运行之后

set identity_insert dbo.tbl_A_archive on

我收到此错误消息

An explicit value for the identity column in table 'dbo.tbl_A_archive' can only be specified when a column list is used and IDENTITY_INSERT is ON.

tbl_A 是一个行数和宽度都很大的表格，即它有很多列。我不想手动输入所有列。我怎样才能让它发挥作用？

Answer 1

SET IDENTITY_INSERT tableA ON

您必须为 INSERT 语句创建一个列列表:

INSERT Into tableA ([id], [c2], [c3], [c4], [c5] ) 
SELECT [id], [c2], [c3], [c4], [c5] FROM tableB

不像“INSERT Into tableA SELECT ........”

SET IDENTITY_INSERT tableA OFF
