用純JSP實現按條件查詢數據庫

<% request.setCharacterEncoding("utf-8"); String order = request.getParameter("order"); String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; String url="jdbc:sqlserver://127.0.0.1:1433;instanceName=MSSQLSERVER08;DatabaseName=web"; String username="sa"; String password="123"; String sql=""; Connection dbConn; Class.forName(driverName); dbConn= DriverManager.getConnection(url,username,password); Statement stmt=dbConn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE); if(null!=order && !"".equals(order)){ sql="select * from test1 where " + order; }else{ sql="select * from test1"; } ResultSet rs=stmt.executeQuery(sql); %>

id	城市	經度	緯度	數值
<%=rs.getString(1) %>	<%=rs.getString(2) %>	<%=rs.getString(3) %>	<%=rs.getString(4) %>	<%=rs.getString(5) %>

<% rs.close(); stmt.close(); dbConn.close(); %>
