mysql 存储过程模板：

CREATE PROCEDURE example.proc_Example()
  SQL SECURITY INVOKER
BEGIN

存储过程日志表 sys_procedurelog

CREATE TABLE example.sys_procedurelog (
  Id int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
  IsSuccess tinyint(1) DEFAULT 1 COMMENT '是否成功:0 否;1 是',
  Logger varchar(50) DEFAULT NULL COMMENT '服务名',
  ProcedureName varchar(50) DEFAULT NULL COMMENT '过程名',
  TimeSpan int(11) DEFAULT NULL COMMENT '耗时时长(秒)',
  ErrCode varchar(5) DEFAULT NULL COMMENT '错误代码',
  ErrMessage varchar(200) DEFAULT NULL COMMENT '错误详细信息',
  LogTime datetime DEFAULT NULL COMMENT '日志记录时间',
  PRIMARY KEY (Id),
  INDEX `NON-ProcedureName` (ProcedureName)
)
ENGINE = INNODB
AUTO_INCREMENT = 37813
AVG_ROW_LENGTH = 97

画重点：

创建临时表要放在事务控制外、
