把所有细节问题。解释你做了什么。你看看互联网上的错误吗？ – drum

抱歉代码不是那么清楚我是新的堆栈OVERFLOW所以不知道这个 – Gourav

在你的选择语句可以看到'em.ro_code'什么是EM？同样尝试使用参数化查询来避免sql注入pblm – Sachu

改变这一行

st1.executeQuery("select insp_no,to_char(inspectiondate,'dd-mm-yyyy') inspectiondate from keroseneheader

对此

st1.executeQuery("select insp_no,to_char(inspectiondate,'dd-mm-yyyy') as 'inspectiondate' from keroseneheader
