I am looking to create multiple records based on a single value in a field in MySQL.

I have some data that looks like this in a table in MySQL

item_id | grade
12345 | 01
12346 | 05
12347 | 09-12

I need to transform it into something that looks like this:
12345 | 01
12346 | 05
12347 | 09
12347 | 10
12347 | 11
12347 | 12

Where 09-12 is can be a range of values
