可以执行,可是执行后想删除的那一列还在,请问这是什么问题?部分代码如下:
<%@
page import="java.sql.*,wcl.*"
%>
<%
String s = request.getParameter("id");
Connection conn = null;
Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost/justshow?user=root&password=123");
Statement stmt = conn.createStatement();
stmt.executeUpdate("delete from xueyi where tanwei="+"'s'");
System.out.println("hao");
stmt.close();
conn.close();
%>
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/justshow?user=root&password=123");
