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
