JDBC + JSF,出现错误:参数索引超出范围(2>参数数量,即1) [英] JDBC + JSF, getting error: Parameter index out of range (2 > number of parameters, which is 1)
本文介绍了JDBC + JSF,出现错误:参数索引超出范围(2>参数数量,即1)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我收到此错误:Parameter index out of range (2 > number of parameters, which is 1).
这是我的代码:
Connection con = getConnection();
String query = "select * from game_match where year = ? and (country_1 = '?' OR country_2 = '?')";
PreparedStatement stmt = con.prepareStatement(query);
stmt.setInt(1, year);
stmt.setString(2, country.getName());
stmt.setString(3, country.getName());
ResultSet rs = stmt.executeQuery();
...
我将JSF与JDBC一起使用只是为了参考,这可能与我在JSF中的bean会话有关.
I am using JDBC with JSF just for reference and it may have something do with my bean sessions in JSF.
如果需要,这是完整的堆栈跟踪:

推荐答案
不能将国家/地区参数识别为参数,因为您已将它们放入字符串引号中.只需写
The country parameters are not recognized as parameters since you have put them into string quotes. Just write
String query =
"select * from game_match where year = ? and (country_1 = ? OR country_2 = ?)";
