In contrast when data is placed in a structured type explicit methods such as setGivenName() and setInitials() are used, and we find this approach to be less error-prone. 相反,当数据放置在所使用的结构化类型的显式方法(如setGivenName()和setInitials())中时,此方法出错的几率更小。
A structured type can have subtypes, other structured types that reuse all of its attributes and contain their own specific attributes. 结构化类型可以包含子类型,以及重用其所有属性并包含自己的特定属性的其他结构化类型。
As rows in a table ( a typed table) whose columns are defined by the attributes of the structured type. 对于表(类型化表)中的行,其中的列是根据结构化类型的属性定义的。
For example, if we were to define a structured type called address_t, city might be one of the attributes of this structured type. 例如,如果我们定义了一个称为addresst的结构化类型,那么city可能就是这个结构化类型的一个属性。
You can create a table with structured type columns in the same way that you would create a table using only DB2 built-in data types. 您可以用同样方式使用结构化类型列创建表,也可以只使用DB2内置数据类型创建一个表。
Use the CREATE TYPE statement to create a structured type, and use the DROP statement to delete a structured type. 可以使用CREATETYPE语句创建一个结构化类型,并使用DROP语句删除结构化类型。
If DB2_PROGRAM has not already been defined for the structured type, you can create that group for your structured type. 如果DB2PROGRAM还没有对结构化类型进行定义,那么您可以为结构化类型创建组。
The FROM SQL clause defines the specific function that will be used to transform a value to a built-in data type value representing the structured type. FROMSQL子句定义了特定的函数,可以使用该函数将将一个值转换成表示结构化类型的内置数据类型。
A typed table is a table that is defined with a user-defined structured type. 类型化表是一个使用用户定义的结构化类型定义的表。
Emp_t is the root type, and its definition happens to include the Address_t structured type that we created previously. Empt是根类型,并且它的定义恰好包括我们先前创建的Addresst结构化类型。
An observer method exists for each attribute of a structured type. observer方法是为某个结构化类型的每个属性而存在的。
The constructor function has the same name as the structured type with which it is associated. 构造函数和它关联的结构化类型有相同的名称。
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. 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。
In this case, the table is created with the structured type, and you don't specify individual columns in the table definition. 在这种情况下,表是用结构化类型创建的,并且您不必在表定义中指定单独的列。
They can also store structured type columns or index data. 它们还可以存储结构化类型的列或索引数据。
By default, the name of the casting function is the same as the name of the structured type ( in this case, Engineer_t and Salesperson_t, respectively). 默认情况下,casting函数的名称和结构化类型的名称相同(在这里,这两个名称分别是Engineert和Salespersont)。
When you create a structured type, DB2 automatically creates a constructor function for the type and creates both mutator and observer methods for the attributes of the type. 当您创建结构化类型时,DB2为类型自动创建一个构造函数,并为类型的属性创建mutator方法和observer方法。
The REF USING INTEGER clause specifies that the INTEGER data type will be used to represent the REFERENCE type of this structured type and all of its subtypes. REFUSINGINTEGER子句指定了INTEGER数据类型,将使用这个数据类型表示该结构化类型及其所有子类型的REFERENCE类型。
You can use the constructor function and the mutator method to create instances of the structured type, and then you can insert these instances into the column of a table. 您可以使用构造函数和mutator方法来创建结构化类型的实例,然后将这些实例插入表的列中。
A structured data type is a form of user-defined data type that contains a sequence of attributes, each of which has a data type. 结构化数据类型是一种用户定义的数据类型,它包含了一系列的属性,每一个属性都有一个数据类型。
We will call any data type whose values are composed of component elements that are related by some structure a structured data type, or data structure. 我们称其值由组成元素组成,且这些组成元素通过某种结构而彼此相关,类型结构为结构化数据类型或数据结构。
Thus we see that a structured data type can have operations defined on its composite values, as well as on the component elements of those values. 由此我们知道数据结构可以有定义在其构成值之上的操作。也有定义在这些值的组成元素上的操作。

Finally, direct against the question that have already stored and reason of production is according to scientific development for guidance view with people text, effective concrete countermeasures have put forward and structured our country's serving type government. 最后,针对既存的问题及产生的原因,按照以人为本的科学发展观为指导,提出了构建我国服务型政府的具有可操作性的具体对策。以人为本,促进人的全面发展;
Based on the routing protocols of structured P2P networks, a new type of content-based routing protocol for pub/ sub systems is designed, which is called Identifier Range Based Routing ( IRBR) protocol. 根据结构化P2P网络的路由协议的特点,设计了一种新型的基于内容的路由协议&基于编码区间的路由(identifierrangebasedrouting,简称IRBR)协议。
It is a simple protocol base on XML, used to transmit the structured information and type information. 该协议是一种基于XML的简单协议,用于在Web上交换结构化的数据和类型信息。
In addition, in structured finance, a more popular type to finance, structured model can be more directly measured its financing risk. 另外,在比较流行的结构化融资中,结构化模型可以更加直接的衡量其融资风险。
Structured product is a new type of financial product that includes the features of both fixed income securities and derivatives. 结构性金融产品是指将固定收益证券的特征与衍生产品特征相结合的一类新型金融产品。
This paper considers a stage structured predator-prey model of Beddington-DeAngelis type functional response. The time delay is the time taken from birth to maturity about the prey. 本文讨论一个具有阶段结构的捕食-食饵模型,该模型采用Beddington-DeAngelis功能反应函数,并以食饵从出生到成熟这段时间为时滞来描述系统的生态特征。
