SqliteConnection，同一事务上的多次提交不起作用

如何解决SqliteConnection，同一事务上的多次提交不起作用

我想从流中插入，就像在下面的 Microsoft 文档中一样，但具有间歇性的提交。 为什么我需要添加带问号的行才能让它工作？是否有更好的替代方法来编写此代码？不知道为什么我不能在同一个事务上多次提交。

private static void CreateDatabase(IEnumerable<Ticker> ticks)

        connection.open();

                    "bid_price NUMERIC NOT NULL,bid_size NUMERIC NOT NULL,ask_price NUMERIC NOT NULL," +
                    "ask_size NUMERIC NOT NULL,PRIMARY KEY(id))";

        using (var createCommand = new sqliteCommand(createCommandStr,connection))

            createCommand.ExecuteNonQuery();
        }
