MySQL 执行查询报错：Fatal error encountered during command execution

 

　　MySQL执行查询时，语句中含有@rowNum查询行号的变量时报错，提示Fatal error encountered during command execution .

　　在数据库连接串中添加“Allow User Variables=true;”即可执行查询成功！

　　例如：“Server=192.168.1.XXX;Database=huac_pacs_cs;Uid=root;Pwd=huac123;Charset=utf8;Allow User Variables=true;”
