mysql临时表用法分析【查询结果可存在临时表中】

select * into tmp from maintenanceprocess

create table tmp (select ...)

#单个工位检修结果表上部
drop table if EXISTS tmp_单个工位检修结果表（检查报告）上部;
create table tmp_单个工位检修结果表（检查报告）上部 (select workAreaName as '机器号',m.jobNumber as '检修人员编号',u.userName as '检修人员姓名',loginTime as '检修开始时间',
CONCAT(FLOOR((TIME_TO_SEC(exitTime) - TIME_TO_SEC(loginTime))/60),'分钟') as '检修持续时长'
from maintenanceprocess as m LEFT JOIN user u ON m.jobNumber = u.jobNumber where m.jobNumber = [$检修人员编号] and loginTime = [$检修开始时间]
);#创建临时表
select * from tmp_单个工位检修结果表（检查报告）上部;

BEGIN
#Routine body goes here...
declare cnt int default 0;
declare i int default 0;
set cnt = func_get_splitStringTotal(f_string,f_delimiter);
DROP TABLE IF EXISTS `tmp_split`;
create temporary table `tmp_split` (`val_` varchar(128) not null) DEFAULT CHARSET=utf8;
while i < cnt
do
set i = i + 1;
insert into tmp_split(`val_`) values (func_splitString(f_string,f_delimiter,i));
end while;
