Rather, just the expression resulting from the SQL expression template should be used from the nested measures.

Let's first start with an example of generating the SQL expression for a measure that does not reference any other measures.
我们先给出为一个度量产生SQL表达式的示例，这个度量没有引用其他任何度量。
For each of the measures that are to be in the query, add the SQL expression generated for the measure as a column in the SELECT list.
对于查询中的每个度量，将度量的SQL表达式添加到SELECT列表中作为列。
Then apply the aggregation function to the SQL expression resulting from the SQL expression template to form the SQL expression for the measure.
然后，对从SQL表达式模板产生的SQL表达式应用聚合，形成度量的SQL表达式。
Columns and attributes markers are substituted the same way as they are for attributes, so the SQL expression resulting from the SQL expression template will be.
按照与属性相同的方式，对列和属性标志进行替换，所以从SQL表达式模板产生的SQL表达式是。
When generating SQL expressions for measures that reference other measures, the aggregation function might not be used to form the SQL expression for the nested measures.
如果一个度量引用其他度量，那么在为它产生SQL表达式时，不能使用聚合函数来为嵌套的度量产生SQL表达式。

It can be any expression allowed in DB2 as long as it does not modify any data in SQL or perform any action outside the scope of the DB2 engine.
只要不修改SQL中的数据或不会在DB2引擎以外执行任何操作，则可以使用DB 2允许的任何表达式。
Most of the examples in this article show the transform expression in an SQL UPDATE statement.
本文中的大多数示例在SQLupdate语句中使用转换表达式。
A FLWOR expression is much like a SELECT-FROM-WHERE expression in SQL: it is used to iterate through a list of items and to optionally return something that is computed from each item.
FLWOR表达式非常像SQL中的SELECT - FROM - WHERE表达式——它用于对由多项组成的一个列表进行迭代，并且可以选择返回通过在每一项上进行计算得到的值。
The syntax for the SQL VALUES expression is fairly simple, as shown in Listing 6.
SQLVALUES表达式的语法相当简单，如 清单6 所示。

The application simply sends an SQL UPDATE statement with an embedded XQuery transform expression to the DB2 server (Figure 2).
应用程序只需向DB 2服务器发送一个包含XQuery转换表达式的SQLupdate语句(图2)。
Time-based update detection: This feature is added to SQL using the ROW CHANGE TIMESTAMP expression.
基于时间的更新检测：这个特性通过ROWCHANGE TIMESTAMP表达式添加到SQL中。
This XPath expression is used with other SQL in the stored procedure to return the sum of the payable amount due on the date supplied as input.
这个XPath表达式与存储过程中的其他SQL相结合，返回在输入的日期应该支付的总金额。
In the case where a retrieved column has a value of SQL NULL, then no XPath variable reference expression is assigned to such a value.
如果检索到的列值为SQLNULL，那么不会给此类值分配任何XPath变量引用表达式。
Update 2 is an SQL SELECT statement with the same XMLQUERY function, transform expression, and WHERE clause, as in Update 1.
更新2是一个SQLselect语句，其中包含与更新1相同的XMLQUERY函数、转换表达式和where子句。
The full-text search expression is expressed in an SQL context, and the relevant XML documents are processed in the XQuery context using the db2-fn: sqlquery input function.
全文搜索表达式在sql上下文中表达，相关的XML文档在XQuery上下文中使用db 2 - fn：sqlquery输入函数进行处理。
MongoDB also provides a group function for performing actions like you would do in a group BY expression in SQL.
