Was wondering if it is possible to change the length of this code without changing how the variable functions, its long and might be confusing for others to understand.

```
  $lch = "SELECT worth FROM credit 
     INNER JOIN rawdate ON credit.card_id=_rawdate.card_id 
     WHERE credit.card_id= 
       (SELECT card_id FROM rawdate 
         ORDER BY id DESC LIMIT 1
       )";

```

The database table names are:

> 
> credit: id, card\_id, value
> 
> 
> rawdate: id, card\_id
> 
> 
>
