set_collate
Description:
Unfortunately, collate can vary from provider to provider.
This method accepts collate name as a string but user should provide valid values. For instance, SQLite3 accepts only "BINARY", "NOCASE", and "RTRIM" values. PostgreSQL, on the other hand expects a name of a callable object, e.g. function.
Parameters:

instance of DbIndexField |

collate to set |
