自学java中用jdbc调用SQLServer带返回结果集存储过程但是却发生“The executeQuery method must return a result set”错误
存储过程如下： create procedure exchangeMoney2( @account_id_in bigint,--转入钱的账户 @account_id_out bigint,--转出钱的账户 @exchange_money float--转账金额 )as begin --创建临时表#account create table #account (account_id bigint null,account_name varchar(80) null, account_money money null,add_time datetime null) --将转账前的2个账户信息插入到临时表#account中 insert into #account select * from account where account_id=@account_id_out or account_id=@account_id_in --更新转出账户的余额 update account set account_money=account_money-@exchange_money where account_id=@account_id_out --更新转入账户的余额 update account set account_money=account_money+@exchange_money where account_id=@account_id_in --将转账后的2个账户的账户信息插入到临时表#account中 insert into #account select * from account where account_id=@account_id_out or account_id=@account_id_in --返回临时表#account中的数据 select * from #account --删除临时表#account中的内容 truncate table #account --删除临时表#account drop table #account end jsp页面如下： <%@ page language="java" import="java.util.*" pageEncoding="GB18030"%> <%@page import="java.sql.*"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>调用存储过程</title> </head> <body> <% Class.forName("net.sourceforge.jtds.jdbc.Driver"); String url = "jdbc:jtds:sqlserver://localhost:1433;DatabaseName=webcounter"; Connection conn = DriverManager.getConnection(url,"sa","sa"); String callExchangeMoneyStr = "{?=call exchangeMoney(1,2,100)}"; CallableStatement procedure = conn.prepareCall(callExchangeMoneyStr); procedure.registerOutParameter(1,Types.OTHER); ResultSet rs = procedure.executeQuery(); %> <table border="1" cellpadding="0" cellspacing="0" align="center" width="400"> <tr> <td colspan="4" align="center">转账操作</td> </tr> <tr> <td>账号</td><td>户名</td> <td>余额</td><td>账户生成时间</td> </tr> <tr><td colspan="4" align="center">转账前的账户信息</td></tr> <% int i=0; while(rs.next()){ i++; if(i==3){ %> <tr><td colspan="4" align="center">转账后的账户信息</td></tr> <%} %> <tr> <td><%=rs.getLong("account_id") %></td> <td><%=rs.getString("account_name") %></td> <td><%=rs.getFloat("account_money") %></td> <td><%=rs.getDate("add_time") %></td> </tr> <%} %> </table> </body> </html> 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。
