27417	Migration to change model field case crashes on Oracle	Vackar Afzal	Mariusz Felisiak	"Given the following class

{{{
class MyModel(models.Model):
    somefield = models.CharField(max_length=100)
}}}

if I rename 'somefield' to 'someField' and run make migrations, it will generate a migrations that will rename 'somefield' to 'someField'

On case insensitive backends like oracle, this will result in the following invalid SQL being generated.


{{{
alter table mymodel rename somefield to someField;
}}}

In cases like this, it should simply generate no SQL.

The other option is when prompted for 'did you rename field x to y' , you can say no, which will result in a drop column followed by an add column, but this will result in **all of the existing data in the column being lost**, less than ideal."
