java.sql.SQLException：几何字节字符串必须是小端

我想使用 contains 函数来获取 title 或 question 包含特定值的所有值 . 但是，我收到此错误：

这是代码：

public String getRecentQuestions(String search) throws SQLException {
        PreparedStatement ps=con.prepareStatement("select title, question_id from questions where contains(title, ?) or contains(question, ?) limit 20");
        ps.setString(1, search);
        ps.setString(2, search);
        ResultSet rs=ps.executeQuery();
        StringBuilder sb=new StringBuilder("");
        while (rs.next()) {
            sb.append("<a href='Question.jsp?question=").append(rs.getInt(2)).append("'><h2>");
            sb.append(rs.getString(1));
            sb.append("</h2></a>");
        }
        return sb.toString();
    }

我的PreparedStatement有效， title 列数据类型为 varchar ， question 列数据类型也为 varchar . 提前致谢 .
