一个表达式表是一个包括至少一个逗号的元组，它的长是表中表达式的个数。其中表达式从左到右按顺序计算。

If something is not quite right in the output, is it the regular expressions, the style sheet, or a combination of the two?
与属性相似，度量是组成事实对象的表上的列或列表达式。
Measures, like attributes, are columns or column expressions on the tables that make up a facts object.
FLWR表达式可以完成很多您在xsl样式表中做梦都别想完成的任务。
FLWR expressions can perform many tasks you'd never dream of undertaking in XSL style sheets.
表2展示了定位元素的DOM表达式。
因为XI规则(正则表达式)有其自己的名称空间，所以将它们复制到样式表是可能的。
Since the XI rules (regular expressions) have their own namespace, it's possible to copy them into the style sheet.
维对象或事实对象的属性是组成维对象或事实对象的联结表上的列或列表达式。
The attributes of a dimension or facts object are columns or column expressions on the set of joined tables that comprise the dimension or facts object.
样式表将首先使用正则表达式 /*匹配所传递的文档的根元素。
The stylesheet starts by matching the root element of the document that it is passed, using the regular expression /*.
在这两种情况下，考虑在伪事实表的连接表达式中添加额外的逻辑，这会缩小从维度表返回的连接键值的范围。
In either case, consider adding additional logic in the join expressions to the fake fact table that will reduce the range of join key values that can be returned from the dimension tables.
这些子查询被称作派生表或表表达式。
These sub queries are called derived tables or table expressions.
这可以通过包含行修改时间戳列的表实现，通过定义行修改时间戳列来保存ROWCHANGETIMESTAMP表达式生成的时间戳值。
This is implemented by a table containing a row change timestamp column defined to store the timestamp values generated by a ROW CHANGE TIMESTAMP expression.
表具有一个行修改时间戳列：ROWCHANGETOKEN表达式返回一个从列的时间戳值获得的bigint值。
The table has a row change timestamp column: a row change TOKEN expression returns a BIGINT value derived from the timestamp value in the column.
您可以连接表1中显示的元素(以及其他操作符)并加以组合使用，从而构建(非常)复杂的正则表达式。
You can string together the primitives in Table 1 (and other operators) and use them in combination to build (very) complex regular expressions.
以下脚本将使用通配符表达式% _ MEASURES以及脚本alterTABLE和REORG命令扫描指定的aw事实表。
The script below will scan for AW fact tables named using the wildcard expression % _measures and scripts ALTER table and REORG commands.
表1展示了定位元素的Xpath表达式。
因为XMLSchema本身是XML文档，所以可以写一个将枚举标记转换成您刚刚看到的正则表达式的样式表。
Because an XML Schema is itself an XML document, you can write a style sheet that converts the enumeration markup into the regular expression you just looked at.
下面的语句执行一个XQuery表达式，并以表的形式返回data列中的值。
The following statement executes an XQuery expression and return values as a table from the DATA column.
为说明表达式问题，Wadler的文章使用了表的概念，其中类型为行，函数为列。
To illustrate the Expression Problem, Wadler's paper USES the idea of a table that has types as rows and functions as columns.
与在单个dbspace中保存多个表或索引片段提高了查询性能，这样做胜过将每个分段表达式存储在不同的dbspace中。
Storing multiple table or index fragments in a single dbspace improves query performance over storing each fragmented expression in a different dbspace.
WebSphereApplicationServer v 6.1支持三种表达式方言：简单、具体和完整(表1)。
WebSphere Application Server V6.1 supports three expression dialects: simple, concrete, and full (Table 1).
在该表的每一行中，都有一个路径位置表达式和一个相关的指定列。
In this table for each row, there is both a path location expression and an associated named column.
通过提取出表达式的常用部分，您可以对样式表进行简化。
You can simplify the stylesheet by factoring out a common part of the expressions.
仍然可以在表达式中使用该函数，确定在处理样式表元素的过程中处理程序是否支持某种内置的或扩展的函数。
You can still use this function in an expression to determine if a particular built-in or extension function is supported as the stylesheet element is being processed.
如果忘记编写当前节点的相对表达式，那么最后就会得到如清单7所示的错误样式表。
If you forgot to write expressions relative to the current node, you can easily end up with the wrong stylesheet, as in Listing 7.
