Available parameters are [2, 1, 0, param1, param2, param3] <select id="loginByTeacher" parameterType="String" resultType="User"> SELECT * FROM `user` WHERE LoginID=#{0} and LoginPwd=#{1} AND Role=2 </select>
C#中当参数超过5个时,建议用结构来传递多个参数. 示例代码如下: public struct MyStruct { public string str; public int number; } class Program { static void Main(string[] args) { MyStruct myStruct = new MyStruct(); myStruct.str = "Number :"; myStruct.number = ; MyClass mc =
众所周知,在C++中有三种参数传递的方式: 按值传递(pass by value) #include <iostream> using namespace std; void swap(int a,int b) { int temp = a; a = b; b = temp; } int main() { int a = 0, b = 1; cout << a << " " << b << endl; swap(a,b); c
一.单个参数: public List<XXBean> getXXBeanList(String xxCode); <select id="getXXXBeanList" parameterType="java.lang.String" resultType="XXBean"> select t.* from tableName t where t.id= #{id} </select> 其中方法名和ID一致,
