在这两个字符数据类型之间有两个主要区别。
There are two main differences between these two character data types.
一些应用程序创建只包含字符数据类型的列的表。
Some applications create tables with columns of character data type only.

The remote XML data is serialized into a character data type
可以声明一个新的NAMESPACE常量，这隐式声明了一个字符数据类型的常量。
You can declare a new NAMESPACE constant, which is implicitly made a constant and from the character data type.
它适用于字符数据类型以及COLLATING_SEQUENCE服务器选项没有被设为“Y”的那些数据源。
It applies to character data types and those data sources for which the COLLATING_SEQUENCE server option is not set to 'y.'
然而，如果列是字符数据类型，并且只包含数字字符，那么可以通过将NUMERIC_STRING选项设置为“Y”来表明这一点。
However, if the column is a character data type and contains only numeric characters, you can indicate this by setting the NUMERIC_STRING option to 'y.'
VARCHAR列的最大长度看起来可能足够大了，但是Derby 还提供了更大的字符数据类型，这个类型将在未来的文章中讨论。
The maximum length for a VARCHAR column may seem sufficiently large, but Derby provides larger character data types, which will be discussed in a future article.
智能大对象包括字符大对象(CLOB)和二进制大对象(BLOB)数据类型。
Smart large objects consist of character large object (CLOB) and binary large object (BLOB) data types.
对于数据类型，例如整数或字符，要生成输入域就比较简单，但是对于xml类型的输入参数，就要更复杂一些。
The latter is simple for data types, such as integer or characters, but more complex for input parameters of type XML.
简单的项属性可以是基元数据类型，例如整数或字符串，或者是称为内容的特殊数据类型，这种数据类型用于存储诸如文件字节等批量数据。
Simple properties of items can be primitive data types, such as integers and strings, or a special data type called content, which is used to store bulk data such as the bytes of a file.
当用ucs - 2数据类型调用时，SUBSTR和LENGTH等函数处理字符。
Functions like SUBSTR and LENGTH work with characters when called in conjunction with UCS-2 data types.
智能大对象由字符大对象(CLOBs)和二进制大对象(BLOBs)数据类型组成。
Smart LOBs consist of character large objects (CLOBs) and binary large objects (BLOBs) data types.
数据类型规范：能够通知ui将特定地址的数据显示为具体的数据类型。例如，此地址表示以null结尾的字符串的开始。
Data type specification: the ability to tell the UI to display the data at a given address as a specific data type - for example, this address represents the start of a null-terminated string.
简单的数据类型(字符串、整数等)。
类型可以是基元，如字符串(SDO称它们为“数据类型”，并定义了一个映射到php类型的集合)或复杂类型来代表序列或地址(SDO称它们为数据对象类型)。
Types can be primitives, such as string (SDO calls these "data types" and defines a set mapped to PHP types), or complex types to represent an order or address (SDO calls these data object types).
这意味着，在应用程序中，应该优先选择二进制数据类型，而不是字符类型。
This means that in your application you should prefer binary data types over character types.
对于字符串数据类型，DB 2需要通过它来知道这个链可以增长到多长。
It is needed for string data types so DB2 knows how long the chain can grow.
参数类型和值空间对应于XML模式数据类型；该类型可以是布尔或字符串类型。
The parameter type and value space corresponds to the XML schema data types; it can be of type boolean or string.
可以为RDF文字给定数据类型，如“整数”、“字符串”、“日期”或甚至是“莫尔斯代码”。
RDF literals can be given data types such as "integer", "string", "date", or even "morse code".
您可以看到，这些文档可以存储包括字符串、整数、浮点数、日期、对象、数组等的各种数据类型。
As you can see, these documents can store various data types include strings, integers, floats, dates, objects, arrays and more.
输入参数 “P1”的数据类型是整型，另一个输入参数 “P2” 的数据类型是字符型。
The input parameter named "P1" is of data type integer, the other input parameter "P2" is of type character.
所有规格都支持与产品领域相关的数据类型，比如字符串、数字和与日期相关的数据类型。
All specifications support relevant data types for the product domain, such as string, number, and date-related data types.
从项目集检索的字符串值还需要转换为正确的数据类型。
The string value retrieved from the item set also needs to be transformed into the correct data type.
函数的结果会以CLOB（字符型大型对象）数据类型的形式返回，可容纳1MB 的数据。
The result of the function is returned as a CLOB (Character Large Object) data type that can hold up to 1 MB of data.
数据类型不是字符串。
在使用API来获得并设置项目的值时，只有一个字符串可以用作数据类型。
When using APIs to get and set the value of an item, only a string can be used as the data type.
列容纳特定数据类型的数据，例如整型值或字符串。
The columns hold data of a specific data type, like integer values or strings of characters.
包含数据项的属性基于字符串或整型等数据类型。
Properties that hold data items are based on data types such as a string or integer.
字符串等简单类型将成为SDO上的原生数据类型属性。
Simple types like strings end up as primitive properties on the SDOs.
按照特定的语法编写字符串，让数据库解析为特定的数据类型。
You write it as a string with a certain syntax that allows the database to parse it into the specialized data type.
