1.while循环 DELIMITER $$ DROP PROCEDURE IF EXISTS `sp_test_while`$$ CREATE PROCEDURE `sp_test_while`( IN p_number INT, #要循环的次数 IN p_startid INT #循环的其实值 ) BEGIN DECLARE v_val INT DEFAULT 0; SET v_val=p_startid; outer_label: BEGIN #设置一个标记 WHILE v_val<=p_
循环一般在存储过程和存储函数中使用频繁,这里只给出最简单的示例 while delimiter $$ create procedure test_while() begin declare sum int default 0; declare t int default 5; while t>0 do set sum=sum+1; set t=t-1; end while; select sum; end $$ delimiter ; repeat delimiter $$ create pro
在 MySQL-procedure(cursor,loop) 中将spam_keyword表中的文字全部分割到t表当中,且每一行的字都不重复,那t表可以用来当作一个小字典,只有1000来个字符,这次把t表当作字符来源,写一个”以 t 表为字符库生成不定长随机字符的procedure“. 1.t表使用的是InnoDB引擎,为了有个区别比较,再新建一个t2表,用MyISAM引擎并复制t的数据,共1023行记录 create table t2 like t; alter table t2 engine

You selected "Repeat header rows on each page" or "Keep header rows visible while scrolling" in the tablix properties dialog, but it doesn't seem to work as expected? You might want to try the following four steps if you are using a &q
Operator repeat() is somewhat similar to retry(), but is not for handling operators. In this lesson we learn how repeat works. var foo = Rx.Observable.interval(500) .zip(Rx.Observable.of('a','b','c','d'), (x,y)=>y); var bar = foo.map(x => x.toUpperC
