Mysql报错问题排查

1、sql_mode问题

SET @v_rowcount = 0;
  select count(*) into @v_rowcount from dual
    where exists (select * from businstep where finance_type='5' and businflow_id='0' and step_no=3);
SET @sql = IF(@v_rowcount = 0,"insert into businstep(finance_type,businflow_id,step_no,step_name,step_caption,menu_id,warn_type,pre_step_str,auto_flag) values('5','0',3,'期货清算入账',' ',210106,'0',' ','1');
	","update businstep set step_name='期货清算入账' , step_caption=' ' , menu_id=210106 , warn_type='0' , pre_step_str=' ' , auto_flag='1' where finance_type='5' and businflow_id='0' and step_no=3;");
PREPARE stmt FROM @sql;
EXECUTE stmt;

执行的时候报如下错误：

原因是： sql_mode=oracle 不支持双引号

解决方式为：修改Mariadb的配置文件配置文件路径：/etc/my.cnf.d/server.cnf)，将原有oracle的配置模式中‘ANSI_QUOTES’去除，即将sql_mode的值修改为'PIPES_AS_CONCAT,IGNORE_SPACE,NO_KEY_OPTIONS,NO_TABLE_OPTIONS,NO_FIELD_OPTIONS,NO_AUTO_CREATE_USER' ；
