Fixed #20013 -- A test for sqlall fails under Oracle

    def test_sql_all(self):

        app = models.get_app('commands_sql')

        output = sql_all(app, no_style(), connections[DEFAULT_DB_ALIAS])

        self.assertTrue(output[0].startswith('CREATE TABLE'))

        if connections[DEFAULT_DB_ALIAS].vendor == 'oracle':

            self.assertEqual(len(output), 4) # Oracle creates a table, a sequence, a trigger and an index

            self.assertIn('CREATE SEQUENCE', output[1])

            self.assertIn('CREATE OR REPLACE TRIGGER', output[2])

            self.assertTrue(output[3].startswith('CREATE INDEX'))

        else:

            # PostgreSQL creates two indexes

            self.assertIn(len(output), [2, 3])

        self.assertTrue(output[0].startswith('CREATE TABLE'))
