mysql创建存储过程中的问题

1.在创建存储过程成功后，使用call存储过程名执行时报错：
Illegalmixofcollations(utf8_unicode_ci,IMPLICIT)and(utf8_general_ci,IMPLICIT)错误。

解决方法：检查存储过程使用到的表格的编码方式，包括字段和表格本身。最后统一编码方式。在类型是属于字符、字符串这等类型的后面加上CHARSETutf8
例：

DELIMITER$$

USE`mall`$$

DROPPROCEDUREIFEXISTS`Prc_AddArticleInfo`$$

CREATEDEFINER=`root`@`localhost`PROCEDURE`Prc_AddArticleInfo`(snamesTEXTCHARSETutf8,contentsTEXTCHARSETutf8,createdtimesDATETIME,voidtimesDATETIME,urlsTEXTCHARSETutf8,cagsVARCHAR(32)CHARSETutf8,usernamesVARCHAR(32)CHARSETutf8)

BEGIN

DECLAREuseridsINTDEFAULT0;

DECLAREgenreidsINTDEFAULT0;

DECLAREsnameTEXTCHARSETutf8DEFAULTNULL;

DECLAREscontentTEXTCHARSETutf8DEFAULTNULL;

DECLAREscreatedtimeTEXTCHARSETutf8DEFAULTNULL;

DECLAREsvoidtimeTEXTCHARSETutf8DEFAULTNULL;

DECLAREsurlTEXTCHARSETutf8DEFAULTNULL;

DECLAREusernameVARCHAR(32)CHARSETutf8DEFAULTNULL;

DECLAREcagVARCHAR(32)CHARSETutf8DEFAULTNULL;

SETsname=snames;

SETscontent=contents;

SETscreatedtime=createdtimes;

SETsvoidtime=voidtimes;

SETsurl=urls;

SETusername=usernames;

SETcag=cags;

SELECTidINTOgenreidsFROMgenresWHERENAME=cag;

SELECTadmin_user_idINTOuseridsFROMadmin_userWHEREadmin_user_name=username;

INSERTINTOarticle(NAME,content,createdtime,voidtime,url,genreid,userid)VALUES(sname,scontent,screatedtime,svoidtime,surl,genreids,userids);

END$$

DELIMITER;

2.mysql报Fatalerrorencounteredduringcommandexecution的解决办法

连接字符串里加上

AllowUserVariables=True

解决。

否则时不时的报错，存储过程名长一点也报错，又有时报有时不报，参数传1位数就正常2位数就报错等……
