用SQL数据库批量插入数据
来源:互联网 发布:人工智能行业投资前景 编辑:程序博客网 时间:2024/05/08 12:18
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
- 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
