循环插入：
复制代码代码如下:
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
