1.sql语句在jsp中的写法 | Copy to clipboard |
Posted by: cenqin8899 Posted on: 2006-10-28 11:10 <=,>=这些在jsp页面中总是被看成是<=的等值,该怎么样写啊?? 求救! 以下是我的部分代码: 大家看一下我的Condi这样写错在哪里?? String Condi="score <="+xuefenmax+"AND"+"score>="+xuefenmin; String condition="SELECT * FROM student where"+Condi; out.println(Condi+", "+condition); // 输出出错!!! try{ Connection conn= DriverManager.getConnection(url,user,password); Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE); ResultSet rs=stmt.executeQuery(condition); |

Posted by: 批 Posted on: 2006-11-01 23:17 为什么不用PreparedStatement String condition = "select * from student where score <= ? and score>=?"; Connection conn= DriverManager.getConnection(url,user,password); PreparedStatement ps=conn.PreparedStatement(condition); ps.setInt(1,xuefenmax); ps.setInt(2,xuefenmin); ResultSet rs=ps.executeQuery(); |
