Suppose the table T has three columns, 

```
 id int not null auto_increment,
 my_id int,
 name varchar(200). 

```

and the query is "select \* from T where my\_id in (var\_1, var\_2, ..., var\_n) and name = 'name\_var'".

Is there any performance difference between below two indices?

* Index1: (my\_id, name)
* Index2: (name, my\_id).
