使用Go语句生成数值表

-- 创建测试表
use tempdb
go

CREATE TABLE [dbo].[Tally](

[int] IDENTITY(1,1) NOT NULL,
CONSTRAINT [PK_Tally] PRIMARY KEY CLUSTERED
(
ASC)) ON [PRIMARY]

-- 设置环境
SET NOCOUNT ON
GO
SET IDENTITY_INSERT dbo.Tally ON;
GO
-- 插入首行数据
INSERT dbo.Tally(N) VALUES(IDENT_CURRENT('dbo.Tally'));
GO

-- 重复10000次插入10000行记录，本本上大约花费7s
INSERT dbo.Tally(N) VALUES(IDENT_CURRENT('dbo.Tally')+1);
GO 10000

-- 恢复环境
SET IDENTITY_INSERT dbo.Tally OFF;
GO
SET NOCOUNT OFF
GO

-- 验证结果
SELECT count(1) as TotalNums FROM dbo.Tally;
GO
/*
TotalNums
-----------
10001
