istartswith
On the page: https://docs.djangoproject.com/en/dev/ref/models/querysets
/#field-lookups we can read:
''istartswith
Case-insensitive starts-with.
Example:
Entry.objects.filter(headline__istartswith='will')
SQL equivalent:
SELECT ... WHERE headline ILIKE 'Will%';''
But there is no db backend which uses ILIKE. LIKE will be used for MySQL.
Again if you assume MySQL by default in documentation then:
''startswith
Case-sensitive starts-with.
Example:
Entry.objects.filter(headline__startswith='Will')
SQL equivalent:
SELECT ... WHERE headline LIKE 'Will%';
''
is incorrect because LIKE BINARY will be used.
The same for contains, icontains, endswith and iendswith.
