用SQL數據庫批量插入數據簡介

編輯:關於SqlServer

最近忙於公司BI軟件性能測試,這幾天主要測試CUBE采用ROLAP下,PA的並發和穩定性。涉及表和維度,立方:事實表sales_fact_1997,維度表time_by_day;立方:sales。修改內容:刪除原來的TIME維度,新建TIME維度,修改SALES立方。

數據插入:

1、事實數據插入:通過DTS加調度實現將sales_fact_1997的數據進行復制。頻率為每分鐘10000條。主要用到的SQL語句:select top 10000 * from sales_fact_1997

2、維度數據插入:通過SQL語句插入數據到time_by_day.

測試用到的SQL語句:

1、單條插入

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、單條插入:

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、循環插入:

DECLARE @MyCounter INT
SET @MyCounter = 0      /*設置變量*/
WHILE (@MyCounter < 2)   /*設置循環次數*/
BEGIN
WAITFOR DELAY '000:00:10'  /*延遲時間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、插入以時間為變量的數據

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
