统计数据表明Oracle认为大多数表只包含1行。这是真的吗？还是需要为甲骨文收集一些适当的统计数据？ –

托尼，你好，查询实际上返回10行，它需要我11秒，只是为了显示这些行。 – GianIsTheName

一个建议，尝试使用sqlfiddle.com或任何其他选择，如果有这样的问题之一。如果您为所有创建的表提供了sqlfiddle，您将会尽快得到答案。 – Bren

它看起来像几乎所有的表都只有一行。在这种情况下，全表扫描会更快。您可以通过指定FULL提示来实现此目的。

嘿史蒂夫。我想知道如何做到这一点。我对Oracle非常陌生。非常感谢。 – GianIsTheName

oracle文档是你的朋友http://docs.oracle.com/cd/B19306_01/server.102/b14211/hintsref.htm，当然还有谷歌。 – steve
