Last month, I talked about querying db4o using both native and QBE-style queries.
上个月，我谈到了使用原生和QBE样式的查询来查询db4o。
I demonstrated data retrieval using db4o's QBE engine last time, but I'll quickly recap here.
上一次我使用了db4o的QBE引擎演示了数据检索，这里将快速回顾一下。
This also points out a limitation of the QBE approach -- zero cannot effectively be used as a value to search on.
（这同样指出了QBE方法的一个缺点 ——不能够有效地使用0作为搜索值）。
The second option pollutes the simplicity of the QBE approach and leads to monstrosities like the one shown in Listing 9
第二种方法破坏了 QBE 方法的简单性，并且导致了如清单9 所示的糟糕代码
Because QBE USES a prototype object as its template to search for data, there are a few simple rules regarding its usage.
由于QBE使用原型对象作为其模板来搜索数据，关于其用法有一些简单的规则。
This paper proposes an indexing algorithm of clustering which supports QBE image retrieval for large image databases.
本文提出了一种有效的支持海量图像数据库Q BE查询的聚类索引算法。
What is apparent from Listing 7, however, is that its usage is arguably not much simpler than the basic QBE version shown already?
然而，可以从清单7中很明显地看到，这种用法并没有比基本的QBE版本简单多少。
