mysql存储过程示例: USE 数据库名称;DROP PROCEDURE IF EXISTS 数据库名称.存储过程名称;delimiter $$CREATE PROCEDURE 数据库名称.存储过程名称(in v_count bigint)BEGIN set @vi=1;set @vcount=v_count; select ceil(round(count(0)/@vcount,2)) into @vnum from 字段1; while(@vi<=@vcount) doif @vi=100
一.创建游标 游标用declare语句创建.如下面的例子所示: create procedure test2() begin declare cursorTest cursor for select * from allIntersection; end; 二.打开.关闭游标 打开游标 open cursorTest; 关闭游标 close cursorTest; close 释放游标使用的所有内部内存和资源,因此在每个游标不再需要时都应该关闭.在一个游标关闭后,如果没有重新打开,则不能使用它.
