最近忙于公司BI软件性能测试，这几天主要测试CUBE采用ROLAP下，PA的并发和稳定性。涉及表和维度，立方：事实表sales_fact_1997,维度表time_by_day；立方:sales。修改内容：删除原来的TIME维度，新建TIME维度，修改SALES立方。

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
