mysql 儲存過程

1、要想檢視儲存過程，用如下命令：

show create procedure  proc_dealwith_cs_incomingrecords;

refurl:

2、執行儲存過程:

call proc_dealwith_cs_incomingrecords('2015-01-27');

利用call命令，然後加上引數即可。這個在除錯時非常有用。

refurl:

3、刪除儲存過程:

drop procedure proc_dealwith_ec_incomingrecords

4、建立儲存過程:

create  procedure `proc_dealwith_cs_incomingrecords`(in `p_in` date)

begin
/*1.first delete temp*/
delete from temp;
/*2.1 sum by province*/
insert into temp(province,businessname,count,incomingtime)
select province,businessname,count(*) as 'cnt',date_format(incomingtime,'%y/%m/%d') as incomingtime2
from t_incoming_records
where date_format(incomingtime,'%y/%m/%d')=p_in and type=0
group by province,businessname,incomingtime2;
/*2.2 sum by city*/
insert into temp(province,businessname,count,incomingtime)
select city,businessname,count(*) as 'cnt',date_format(incomingtime,'%y/%m/%d') as incomingtime2
from t_incoming_records
where date_format(incomingtime,'%y/%m/%d')=p_in and type=0 and city in (convert('青島市' using utf8),convert('深圳市' using utf8),convert('蘇州市' using utf8),convert('寧波市' using utf8))
group by city,businessname,incomingtime2;
/*3.row to column*/
insert into t_cs_incoming_report(institution,report,compensation,complaint,inquiry,other,yijianxian,incomingtime)
select province as institution,
sum(case when businessname=convert('1' using utf8) then count end) as 'report',
sum(case when businessname=convert('3' using utf8) then count end) as 'compensation',
sum(case when businessname=convert('4' using utf8) then count end) as   'complaint',
sum(case when businessname=convert('2' using utf8) then count end) as  'inquiry',
sum(case when businessname=convert('6' using utf8) then count end) as 'other',
sum(case when businessname=convert('5' using utf8) then count end) as 'yijianxian',
incomingtime
from temp
group by institution;
end

2)在首尾加上begin和end,中間就是普通的sql**塊。
