MySQL存储过程

注：name是存储过程的名字
//TODO：存储过程
//传参
// $aid1 = ‘report_aid’;
// $main2 = "call sample_num('".$aid1."’)";
// $result2 = Db::query($main2);

// $res = Db::query(‘call name(:in_param1,in_param2,)’,
// [
// ‘in_param1’ => $in_param1,
// ‘in_param2’ => $in_param2,
// ]);

$res = Db::query(‘call name’);
//如果存储过程不需要返回数据
Db::execute(‘call name’);

数据库-存储过程代码

传入的参数声明

注：数据库函数过程（传入的是不同字段时）
