Sql server 如何填充仅包含标识列的表？

考虑下表

CREATE TABLE [dbo].[Numbers]
(
    [Id] [INT] IDENTITY(1,1) NOT NULL
) ON [PRIMARY]

如何填充它

如果我添加一列文本nchar20，那么我可以用以下内容填充它：

insert into numbers (text) values ('')

但是，如果除了标识之外没有其他列，我该怎么办

insert into numbers ( ) values ( )

这会抛出一个错误

附近的语法不正确

我想用它来查找缺少序列号的问题。

指定默认值：

或者，您甚至可以使用：

样本：

CREATE TABLE [dbo].[Numbers](
    [Id] [int] IDENTITY(1,1) NOT NULL
) ON [PRIMARY];

DECLARE @Start INT=1;
DECLARE @End INT=100;

SET IDENTITY_INSERT [dbo].[Numbers] ON;
WITH Gen AS (
    SELECT @Start AS Num
    UNION ALL
    SELECT Num + 1 FROM Gen WHERE Num + 1 <= @End
)
INSERT INTO [dbo].[Numbers] (Id)
SELECT Num 
FROM Gen
OPTION (maxrecursion 100);

SET IDENTITY_INSERT [dbo].[Numbers] OFF;

SELECT *
FROM [dbo].[Numbers];

我认为你不应该有一个1列标准化的表格，如果你想识别缺失的数字，为什么不使用理货表呢？@Lamu谢谢。我查了一下athttps://blogs.technet.microsoft.com/benjamin/2018/02/06/sql-tip-the-tally-table/L 一个R N U。没有M。啊，我的视力，对不起@Larnu

SET IDENTITY_INSERT YourTable ON;  
GO 
INSERT INTO YourTable (IdentityColumn) VALUES
(1),
(2),
(3);
GO
SET IDENTITY_INSERT YourTable OFF;

CREATE TABLE [dbo].[Numbers](
    [Id] [int] IDENTITY(1,1) NOT NULL
) ON [PRIMARY];

DECLARE @Start INT=1;
DECLARE @End INT=100;

SET IDENTITY_INSERT [dbo].[Numbers] ON;
WITH Gen AS (
    SELECT @Start AS Num
    UNION ALL
    SELECT Num + 1 FROM Gen WHERE Num + 1 <= @End
)
INSERT INTO [dbo].[Numbers] (Id)
SELECT Num 
FROM Gen
OPTION (maxrecursion 100);

SET IDENTITY_INSERT [dbo].[Numbers] OFF;

SELECT *
FROM [dbo].[Numbers];
