插入1到10,000之间的数字 [英] Inserting numbers from 1 to 10,000

问题描述

我想在sql中插入1到10,000个数字。我运行了以下内容并且也正确地执行了。

I wanted to insert 1 to 10,000 numbers in sql. i've run the following and it exectuted correctly as well.

DROP TABLE NumbersTest
DECLARE @RunDate datetime
SET @RunDate=GETDATE()
CREATE TABLE NumbersTest (Number INT NOT NULL);
DECLARE @i INT;
SELECT @i = 1;
SET NOCOUNT ON
WHILE @i <= 10000
BEGIN
    INSERT INTO dbo.NumbersTest(Number) VALUES (@i);
    SELECT @i = @i + 1;
END;
SET NOCOUNT OFF
ALTER TABLE NumbersTest ADD CONSTRAINT PK_NumbersTest PRIMARY KEY CLUSTERED (Number)
PRINT CONVERT(varchar(20),datediff(ms,@RunDate,GETDATE())/1000.0)+' seconds'
SELECT COUNT(*) FROM NumbersTest

select * from NumbersTest

现在我的问题是我知道日期时间部分。谁可以解释一下？

Now my question is i din understood that date time part. can any one explain about that?
