java mysql 存储过程 乱码

环境：MYSQL数据库本身是UTF8+客户端是UTF8连接的

如果在这种情况下，存储过程依然是乱码的话，那么原因如下：

 

1、定义了变量。变量必须也要以UTF8定义。

2、用了中文字符串作比较，此时要将中文转化成UTF8编码，否则乱码。

      具体方法：

 

CREATE PROCEDURE proc_dealwith_incomingrecords(IN p_in date)


BEGIN
/*1.FIRST DELETE temp*/
DELETE from temp;
/*2.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
group by province,businessName,incomingTime2;
/*3.row to COLUMN*/
INSERT into t_cs_incoming_report(institution,report,compensation,challenge,inquiry,other,incomingTime)
SELECT province as 'institution',
sum(CASE WHEN businessName=convert(_utf8'报案' using utf8) THEN count END) as 'report',
sum(CASE WHEN businessName=convert(_utf8'承保理赔' using utf8) THEN count END) as 'compensation',
sum(CASE WHEN businessName=convert(_utf8'投诉' using utf8) THEN count END) as   'complaint',
sum(CASE WHEN businessName=convert(_utf8'咨询' using utf8) THEN count END) as  'inquiry',
sum(CASE WHEN businessName=convert(_utf8'其他服务' using utf8) THEN count END) as 'other',
incomingTime
from temp
GROUP BY 'institution';
end;

ps:在Navicat for mysql的软件版本其实蛮好的，调用存储过程如下：

1、随便打开一个查询窗口

2、输入如下语句：

set @p_out=1;
call proc2(@p_out);

 然后会在下文出现结果1，结果2等。
