I have a query to exclude all entries with an empty char field. This works
as expected on sqlite and Postgres, but fails on Oracle.
On Oracle the exclude does not exclude a single item.
{{{
valid_accounts = get_bank_accounts().exclude(account_number='')
}}}
SQL generated for Postgres looks like this (the exclude part only):
{{{
AND NOT ("accounts"."account_number" = ))
}}}
On Oracle, it looks like this:
{{{
AND NOT (("ACCOUNTS"."ACCOUNT_NUMBER" IS NULL
AND "ACCOUNTS"."ACCOUNT_NUMBER" IS NOT NULL))
}}}
So, in order to work on Oracle, I have to resort to:
{{{
valid_accounts = get_bank_accounts().filter(account_number__gte=1)
}}}
