最近忙于公司BI軟件性能測試，這幾天主要測試CUBE采用ROLAP下，PA的并發和穩定性。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 |
