SQL数据库批量插入数据

数据插入： 

1、事实数据插入：通过DTS加调度实现将sales_fact_1997的数据进行复制。频率为每分钟10000条。主要用到的SQL语句：select top 10000 * from sales_fact_1997 

2、维度数据插入：通过SQL语句插入数据到time_by_day. 

测试用到的SQL语句： 

1、单条插入 


INSERT INTO time_by_day 

(time_id, the_date, the_year, month_of_year, quarter,day_of_month) 

VALUES ('1101', '1999-10-1', '1999', '10', 'Q4','1')


2、单条插入: 


INSERT INTO time_by_day 

(time_id, the_date, the_year, month_of_year, quarter, day_of_month) 

SELECT TOP 1 time_id + 1 AS time_id, the_date + 1 AS the_date, YEAR(the_date + 1) 

AS the_year, MONTH(the_date + 1) AS month_of_year, { fn QUARTER(the_date + 1) 

} AS quarter, DAY(the_date + 1) AS day_of_month 

FROM time_by_day 

ORDER BY time_id DESC


3、循环插入： 


DECLARE @MyCounter INT 

SET @MyCounter = 0 /*设置变量*/ 

WHILE (@MyCounter < 2) /*设置循环次数*/ 

BEGIN 

WAITFOR DELAY '000:00:10' /*延迟时间10秒*/ 

INSERT INTO time_by_day 
(time_id, the_date, the_year, month_of_year, quarter, day_of_month) 

SELECT TOP 1 time_id + 1 AS time_id, the_date + 1 AS the_date, YEAR(the_date + 1) 

AS the_year, MONTH(the_date + 1) AS month_of_year, { fn QUARTER(the_date + 1) 

} AS quarter, DAY(the_date + 1) AS day_of_month 

FROM time_by_day 

ORDER BY time_id DESC 


SET @MyCounter = @MyCounter + 1 

END


4、插入以时间为变量的数据 


DECLARE @MyCounter INT 

declare @the_date datetime 

SET @MyCounter = 0 

SET @the_date = '1999-1-4' 

WHILE (@MyCounter < 200000) 

BEGIN 

WAITFOR DELAY '000:00:10' 

/*INSERT INTO time_by_day 

(time_id, the_date, the_year, month_of_year, quarter, day_of_month) 

SELECT TOP 1 time_id + 1 AS time_id, the_date + 1 AS the_date, YEAR(the_date + 1) 

AS the_year, MONTH(the_date + 1) AS month_of_year, { fn QUARTER(the_date + 1) 

} AS quarter, DAY(the_date + 1) AS day_of_month 

FROM time_by_day 

ORDER BY time_id DESC 

*/ 

insert into time_by_day (time_id,the_date)values('371',@the_date) 

SET @the_date = @the_date + 1 

SET @MyCounter = @MyCounter + 1 

END

自己写的一个实验：

View Code

1 DECLARE @mycount INT
2 SET @mycount = 0
3 WHILE ( @mycount < 9 )
4 BEGIN
5 WAITFOR DELAY ' 000:00:10 '
6 INSERT INTO dbo. [ User ]
7 ( ID ,
8 FristName ,
9 LastName ,
10 DepartName ,
11 City
12 )
13 SELECT TOP 1 ID + 1 , -- ID - int
14   ' zhou ' + CONVERT ( NVARCHAR , @mycount ) , -- FristName - varchar(50)
15   ' xiuguan ' + CONVERT ( NVARCHAR , @mycount ), -- LastName - varchar(50)
16 ' test ' + CONVERT ( NVARCHAR , @mycount ), -- DepartName - varchar(50)
17 ' wuqiao ' + CONVERT ( NVARCHAR , @mycount ) -- City - varchar(50)
18 FROM dbo. [ User ] ORDER BY ID DESC
19
20 SET @mycount = @mycount + 1
21 END

首先数据库中有条数据，再执行该循环，结果如下图：
