As I started this challenge, I hadn't MySQL installed on my machine and I wanted to procede without installing new software.
For this challenge, I opened the sql file in my text editor and I extracted the part where we inser `consumers`.
```sql
INSERT INTO `customers` VALUES (1,'Hanstock','Juditha','[email protected]','06 Everett Crossing','Indianapolis','IN','US','46239','F','12/10/1967'),(...),(...) ...
```
I figured out that each consumer is sorrounded by parenthesis, so I just searched for the number of parenthesis in that part and I found the solution : 10000 consumers.
