有什么不同寿命的复合类型和标量类型?。
What is the difference of lifetimes of compound types and scalar types?
可在可用于数据规则的所有测试及函数执行类型的概述部分，找到哪些测试及函数是标量的以及哪些是柱状的。
You will find an overview of which tests and functions are scalar and columnar in the overview of the execution types of all tests and functions available for data rules.
可以使用初始化器列表对标量变量进行初始化，在这种情况下应用一般的类型窄化规则。
It's okay to use initializer lists to initialize scalar variables, and the usual rule of type narrowing applies in such cases.
因为这都是些标量函数，所以将为结果集的每一行创建XML数据类型的结果。
Since these are scalars functions, for each line of the result set, a result of the XML data type is created.
总是有必要使用标量函数XML2CLOB (xml - data -type)：clob - data - type来将xml内容串行化为clob数据类型。
It is always necessary to use the scalar function XML2CLOB (xml-data-type) : clob-data-type to serialize the XML contents in a clob data type.
改变了类型强制规则，以保持数组(更为常见)中的类型 ，而不是转换为Python 标量的类型。
The type coercion rules have changed to preserve types in arrays (more often), rather than converting to the type of a Python scalar.
为了从表中检索结构化类型数据，必须有一些将类型转换成一个标量值，换句话说，这些值的类型必须基于某种内置的DB2 数据类型。
To retrieve structured type data from a table, there must be some way to convert that type into a single scalar value whose type, in turn, must be based on one of the built-in DB2 data types.
在DB 2中有两种类型的UDF：标量函数(scalar function)和表函数(table function)。
There are two types of UDFs in DB2: scalar and table functions.
与实体相似，复杂类型由标量属性或者其他复杂类型属性组成。
Like entities, complex types consist of scalar properties or other complex type properties.
指出全息菲涅耳透镜是一种特殊类型的光栅。分析并说明光栅的标量衍射理论是计算衍射效率的一种近似方法，因此它的应用是有限制条件的。
We show and illuminate that the scalar diffraction theory is an approximation method to calculate the diffraction efficiency of grating, and there are restrictions on its application.
