But when dealing with a collection of data, the distinction between a null array (which returns null) and an empty array (which returns itself) needs closer attention.
但是，当处理数据集合时，零数组(返回零)和空数组(返回其本身)需要密切关注。
Conventions for addressing null values are also important, as is what to do when we receive bad data.
处理空值的约定也很重要，当我们收到坏数据时就这样做。
One of the problems with not entering this data in regular RDBMS columns is that no rules are defined-no data types, not NULL identifiers and so forth.
未在常规的RDBMS列中输入该数据导致的问题之一是没有定义任何规则——没有数据类型和NOT NULL标识符等。
If the customer number is not null, that is, the customer is already known, the left hand path is followed (2), and the customer data is retrieved from the customer registration service (3).
如果客户编号不为空，即客户是已知客户，则遵循左侧的路径(2)，并从客户注册服务中检索客户数据(3)。
For instance, you don't need to check whether the data contains null characters because an XML parser will never pass you a null.

NULL values of compatible data types are treated identically; those of non-compatible data types may not be.
对兼容数据类型的NULL值的处理是完全相同的；对不兼容数据类型的 NULL 值的处理可能不相同。
Without value compression, NULL values are stored with the data type inherent fixed size, which is typically larger than the three bytes.
如果不使用值压缩，则null值以数据类型固有的固定大小存储，这通常大于3个字节。
This may be in the form of Null values or other blank value conditions (for examples, Spaces) for one or multiple data elements of the entity.
对于实体的一个或多个数据元素，这可能以null值或空白值(例如空格)的形式出现。
This may be in the form of Null values or other blank value conditions (for example, Spaces) in situations where the data is required.

In some cases, there is no data in the database corresponding to the requested bean; the container returns a null, as there is no bean matching the client's request.
有些情况下，数据库中并没有与请求的bean对应的数据；则容器返回空，因为没有bean与客户机的请求匹配。
Weakly-typed collection objects, arrays containing null elements, and certain native data types all pose special problems for interoperability. Specifically
弱类型的集合对象、包含空元素的数组和特定的本地数据类型都给互操作性带来一定的问题，特别是
The single quotation mark in front of the null list is used to tell Scheme that you are using as data and not as a part of your parse tree.
空列表前面的单引号用来告诉scheme您正在使用作为数据，而不是用它作为解析树的一部分。
Here the null or blank value does not represent incomplete data, but reflects that the business condition requiring the data has not yet occurred.
在这里，null或空白值并不表示不完整的数据，而是反映需要尚未出现的数据的业务情况。
Conversion and validation allow you to focus on business logic rather than the tedious qualifications of input data such as null checks, length qualifiers, range boundaries, etc.
转换和验证使您可以侧重于业务逻辑，而不是侧重于对输入数据进行繁琐的资格认定，比如null检验、长度限定、范围边界，等等。
The SQL query USES the stored procedures to create one XML listing element per row of data returned, passing in null as the column to obtain its value from because its value is its subelements.
SQL查询使用存储过程为每行返回数据创建一个xml列表元素，同时传递null作为列以获取值，因为它的值就是它的子元素。
If a field in the prototype is "null," then that value matches against any value in the data store; otherwise, the values must match exactly.
如果原型中的字段值为“null”，则该值匹配数据存储中的任何值；否则的话，必须精确地匹配值。
If the HTTP method is GET (currently not used by JSF forms), the form data has already been appended to the URL and send is called with a null parameter.
如果HTTP方法是GET(当前未被JSF表单使用)，那么表单数据应该已经追加到此url，并会用null参数调用send 。
When you don't need to pass data along through send , then just pass null as the argument to this method.
如果不需要通过send传递数据，则只要传递null作为该方法的参数即可。
In addition to the actual data, DB2 needs to maintain the mandatory null indicator (1 byte) and length information (4 bytes).
除了实际的数据外，DB 2需要维护强制的null指示符(1个字节)和长度信息(4个字节)。
