Import MySQL database Newbir Question

Good day,

I run a mysql server on Linux.

I have a mysql database dumpfile on a  prodserver . I would like to create a NEW DB on the same server and import this backup into it..  

I have logged in, and created a database like this:

Mysql> create database testmax;
Query OK, 1 row affected (0.06 sec)
mysql> use testmax;
Database changed
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| phpmyadmin         |
| procorp            |
| testmax            |
+--------------------+

(I want to import  procorp's backup in testmax)

Now, I am at the part where i want  to populate this testmax  database with my existing  procorp backup. I also want to make sure i dont overwrite the procorp database (production database)

How do I do that?

I know in Oracle you can set ORACLE_SID but im not familiar with mysql.
