在select语句中使用视图,可以限制表的连接顺序,同时也限制查询优化器在考虑访问计划时的选择。
Using views in a SELECT statement can restrict the join order of the tables and limit the query optimizer's choices when considering access plans.
每一个查询都包含相同数量的项目,它们具有相同的名称和顺序,这样它们就能够在第三个查询中实现联合。
Each query will contain the same number of items with the same names and in the same order so that they can be unioned in the third query.
还可以使用伪列值按照宽度优先顺序对查询结果进行排序。
The pseudo column value is also used to sort the query results in breadth-first sequence.

它包括所使用的索引、从数据库表中检索字段的次数,以及执行查询的步骤的顺序。
It includes the indexes that are used, The Times at which fields are retrieved from the database tables, and the order of steps in which the query is executed.
如果查询涉及到顺序谓词,不要改变模式中的元素顺序。
Do not change the order of the elements on the schema when the queries consider ordered predicates.
定义了列的查询元素表中的行顺序决定了它们在ORDERBY子句中从左到右的顺序,这又确定了它们的排序优先级。
The row order in the query elements table in which columns are defined determines their left to right sequence within the order BY clause, which in turn determines their sorting priority.
该文件不仅对用于查找信息的源进行配置,而且也用于配置不同源的查询顺序。
The file configures not only the sources used to locate the information, but also the order in which the different sources are queried.
DB 2行压缩功能可以减少磁盘存储需求,同时改进执行全表扫描的大量查询的顺序读取访问。
DB2 row compression features can decrease disk storage requirements while at the same time improve sequential read access of large queries which perform full table scans.
最重要的是,它只能用于soap格式的消息,并且不能修改消息部分的类型或者消息查询的顺序,而对于大容量情况而言,这一点有时是至关重要的。
Most importantly, it is usable only for SOAP-formatted messages, and it cannot modify message part types or sequence of message interrogations that is sometimes critical in high-volume situations.
搜索这些域的顺序是不确定的,因此如果匹配帐户存在于多个域中,则无法预先知道哪个帐户实例将解析查询。
The order of this domain search is undetermined, so if a matching account exists in more than one domain, it is not possible to know in advance which instance of the account will resolve the inquiry.
通常,查询的连接顺序很大程度上决定了查询的执行性能,因为越早地过滤行,效率越高。
Often the join order of a query will greatly determine the query execution performance, since it is more efficient to filter rows as early as possible.
所有的REST查询必须通过签名令牌签名的方式进行认证,该过程通过对按小写的字母顺序排序的查询参数使用私钥进行签名。
All REST queries must be authenticated by signing the query parameters sorted in lower-case, alphabetical order using the private credential as the signing token.
切换到ResultLayout页面,并选择列和最适合您的查询结果的排序顺序。
Switch to the result Layout page and choose the columns and sort order that best suit your query results.
当您对ApacheDerby处理查询时执行的过程进行分解时,该顺序十分直观。
When you break down the process Apache Derby follows when processing a query, this order is intuitive.
假设需要将前面XPath查询(清单2)返回的结果按照字母顺序排列,如清单3所示。
Suppose you wanted to return the results from the earlier XPath query (Listing 2) in alphabetical order, as shown in Listing 3.
让我们通过以下示例来逆向工作:假设指定查询Nathen,我们需要按照该顺序匹配nathan和Jonathan的数据项。
Let's work backward, instead, with the following example: with a specified query of Nathen, we want to match data entries of Nathan and Jonathan, in that order.
对fraggle . py中查询的一个明显改进是根据源进行分组,而不是单单根据时间顺序进行显示。
One obvious improvement to the query in fraggle.py would be to group by source, rather than pursuing just a time-ordered display.
清单中的查询将按日期顺序返回parking_tickets数据库中的所有文档。
The query in Listing 9 returns all the documents in the parking_tickets database sorted by date.
影响XML查询中的连接顺序和连接方法。
我执行读取操作的顺序是从web层获取请求(需要执行一次数据库查询)并检查之前在缓存中存储的查询结果。
The sequence I follow when performing reads is to take a request (that requires a database query) from the Web tier and check the cache for previously stored results of that query.
添加一个ORDERSIBLINGSBY子句,该子句只能与分级查询子句组合使用,并且将按预先定义的顺序返回同级查询结果。
Adding an ORDER siblings BY clause which is only allowed in composition with the hierarchical query clause and will return the siblings in the predefined sequence.

Enable the user to add several modules, stacked in chronological order as the user builds up a complicated query.
允许用户添加额外的过滤项以时间顺序以帮助用户建立一个复杂的搜索查询。
