  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

  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
