Specifies that the associated data column is used to sort the query results and whether the sort is ascending or descending.
指定数据列的附加搜索条件表达式,并用逻辑OR链接到先前的表达式。
Specifies an additional search condition expression for the data column, linked to previous expressions with a logical OR.
在执行发现时,其惟一的数据列(attrval)可能会作为目标字段不止一次出现。
When performing discovery, its only data column (attrval) may appear more the once as the target field.
若要控制数据列在结果集中出现的位置或数据列的使用顺序,可对列重新排序。
To control where a data column appears in the result set, or in what order it is used, you can reorder the columns.
查询将一个或多个特定XML元素或属性节点值映射到同等数量的关系数据列(参见图6)。
The query maps one or more specific XML element or attribute node values to an equal number of relational data type columns (see Figure 6).
原因是返回此值使用的逻辑内置于生成的数据集类中特定数据列的属性设置程序。
The reason for this is that the logic to return this value is built into the property setter of the specific data column in the generated dataset class.
UTF - 8被选择为字符数据列的默认格式,其中U TF - 16用于图形数据列。
UTF-8 was chosen as the default format for character data columns, with UTF-16 for graphic data columns.

According to the sequence of the soil creeping failure time under different loading conditions, a grey forecasting model for the failure time in the course of soil creeping is established.
请问,运用ADO访问数据库时,如何知道数据库系统中有那些数据表以及表中有那些数据列?
I ask, using ADO to access database, how to know the database system in the data tables and table columns in the data?
例如,假设您想要计算其XML数据列的text元素的值为Thisshould validate !的行的数量。
For example, suppose you want to perform a count of the rows where the XML data column has an element text with the value This should validate!.
实际上,这类null值是一种数据列重载,并且在这个上下文中,null值可能被理解为表示数据的某些方面。
In effect, such a null value is a type of data column overloading, and in this context, a null value might be understood to represent some aspect of the data.
提出了“利用反双曲正弦函数变换提高数据列光滑程度”的新结论,获得了递增时间序列改善的自回归预测新方法。
A new conclusion is put forward, in which the smooth degree of the data row can be enhanced by means of the arc-hyperbolic sine function transformation.
保留的扩展表字段:在每个表中预先定义固定数量的额外数据列,这些列采用通用列类型(比如varchar)。
Reserved extended table field: Pre-define a fixed number of additional data columns in each table with a generic column type (e.g. varchar).
所以,即使数据列不是GROUPBY子句的一部分或者不包含在聚合函数中,也可以在 WHERE 子句中使用它。
Therefore, you can use a data column in a WHERE clause even if it is not part of the GROUP BY clause or contained in an aggregate function.
在图5中,RegexGroups函数定义与RegexMatches函数定义一样,除了它还返回匹配项中包含组名称的其他数据列。
In Figure 5, the RegexGroups function is defined like the RegexMatches function except that it returns an additional column of data containing the name of the group within the match.

Now you will create an SQL script that will simply query the status_updates table and return the XML data stored in each row's data column.
在为每个客户添加数据库实例时,或者在每个表中创建一个数据列以验证客户是否访问合适的数据时,这种设计会大大增加表的数量。
This design increases the number of tables significantly over adding a database instance per customer or creating a column in each table to validate whether the customer is accessing the proper data.
