【中文标题】jsp与oracle数据库连接【英文标题】：connect jsp with oracle database 【发布时间】：2016-07-29 03:27:19 【问题描述】：我编写了以下代码来从我的 oracle 数据库中获取数据并使用 JSP 显示结果：
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import="java.io.*,java.util.*,java.sql.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
<!DOCTYPE html>
<html>
<head>
<title>SELECT Operation</title>
</head>
<body>
<sql:setDataSource var="snapshot" driver="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:@localhost:1521:orcl"
user="hr" password="Hrone699"/>
<sql:query dataSource="$snapshot" var="result">
SELECT No from Client;
</sql:query>
<table border="1" >
<tr>
<th>No</th>
<th>Client</th>
<th>Information Collection Date</th>
<th>Payment Notice Date</th>
</tr>
<c:forEach var="row" items="$result.row">
<tr>
<td><c:out value="$row.No"/></td>
<td><c:out value="$row.Client"/></td>
<td><c:out value="$row.INFOCOLLECTINGDATE"/></td>
<td><c:out value="$row.PAYMENTNOTICEISSUEDATE"/></td>
</tr>
</c:forEach>
</table>
</body>
但我收到以下错误： 发生错误：
从客户那里选择否； : ORA-00911: 无效字符

【问题讨论】：
可能 oracle 得到一些 UTF-8 字符并且不喜欢它。 根据***.com/questions/10728377/…，问题是查询末尾的分号（;）。在 JDBC 调用中是不允许的。
【参考方案1】：
只需从 sql 语句中删除分号（“;”），因为 oracle 驱动程序不需要以分号结束 sql 语句，但是当您使用 mysql 数据库（mysql-connector 驱动程序）时，您必须提及分号（“;”） )
