Question

Class.forName("com.mysql.jdbc.Driver");

Connection conn = DriverManager.getConnection(url, "root", "");
// assuming your SQL Server's username is "username" // and password is "password"

Statement st = conn.createStatement();
String sql = "Select count(role) as totalEmployee from login where role = 'employee'";
ResultSet rs = st.executeQuery(sql);

我在mysql中解雇了这个查询，得到的答案是2。那么如何在jsp页面中获取并显示该查询的结果呢？

Answer 1

您可以迭代结果集并将结果输入变量，如：

  <%
    int totalEmployee = 0;
    if (rs != null && rs.next()) {
         totalEmployee = rs.getInt("totalEmployee");
    }
%>

Answer 2

您还可以显示结果集并将结果输入变量，如：

#!/path/to/python
