?最近忙于公司BI軟件性能測(cè)試，這幾天主要測(cè)試CUBE采用ROLAP下，PA的并發(fā)和穩(wěn)定性。
? 涉及表和維度，立方：事實(shí)表sales_fact_1997,維度表time_by_day；立方:sales
? 修改內(nèi)容：刪除原來(lái)的TIME維度，新建TIME維度，修改SALES立方。
?數(shù)據(jù)插入：
? 1，事實(shí)數(shù)據(jù)插入：通過(guò)DTS加調(diào)度實(shí)現(xiàn)將sales_fact_1997的數(shù)據(jù)進(jìn)行復(fù)制。頻率為每分鐘10000條。
?????????????????????????? 主要用到的SQL語(yǔ)句：select top 10000 * from sales_fact_1997
? 2,維度數(shù)據(jù)插入：通過(guò)SQL語(yǔ)句插入數(shù)據(jù)到time_by_day.
測(cè)試用到的SQL語(yǔ)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(huán)插入：
?
DECLARE @MyCounter INT
SET @MyCounter = 0?????????? ?/*設(shè)置變量*/
WHILE (@MyCounter < 2)??? ?/*設(shè)置循環(huán)次數(shù)*/
BEGIN
WAITFOR DELAY '000:00:10'?? /*延遲時(shí)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(shí)間為變量的數(shù)據(jù)
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
