This allows the entire lookup table to be loaded into memory each time a user submits a request to read or write data.
在用户每次提交一个读写数据的请求时,这可以将要查询的整个表装入内存中。
Note that at the time of creating an external table, the data files associated with the external table need not exist.
注意,在外部表创建之时,与该外部表关联的数据文件不需要存在。
A customer wants to delete large amounts of data on other dimensions than time (which is the column that the table is data partitioned on).

With all the necessary relational values extracted from the source XML column, it's time to aggregate the two values needed for one of the target data warehouse tables (the DWADMIN.ACCT table).
从源xml列提取所有需要的关系值之后,便可以为一个目标数据仓库表(DWADMIN .acct表)聚合这两个值。
The Transformer stage needs to extract time information from an input string containing timestamp data in order to correctly populate the TIMECHANGED column in the target DWADMIN.ACCT table.
Transformer阶段需要从包含时间戳数据的输入字符串提取时间信息,以准确地填充目标DWADMIN.ACCT 表中的 TIMECHANGED列。
To present a table at run time, you have to supply the actual data in a table model, and then associate that table model with the JTable bean.
为了在运行时显示表格,你必须为表格模型提供实际数据,然后将表格模型和JTable bean相关联。
DEFERRED means that the data in the table can be refreshed at any time using the refresh table statement.
DEFERRED的意思是,表中的数据可以在任何时候通过REFRESHtable语句来刷新。
If the data is stored sequentially, the time to find the item is proportional to the size of the list. For each element, a hash function calculates a number, which is used as an index into the table.
如果数据是序列存储的,从中查询一个项的时间取决于数据列的大小。
The design-time environment uses the IDictionaryService on every site to maintain a data table that is used throughout the designer framework.
设计时环境使用每个站点上的IDictionaryService来维护在整个设计器框架中使用的数据表。
The refresh DEFERRED clause means that the data in the table can be refreshed at any time using the refresh table statement.
REFRESHdeferred子句的意思是,在任何时候都可以用REFRESHtable语句刷新该表中的数据。
For system time tables, DB2 also helps store historical data in a history table associated with the temporal table.
对于系统时间表,DB 2还帮助将历史数据存储在一个与时态表相关联的历史表中。
Using a typical star schema database design, a fact table might contain sales data by product, region, and time period.
按照典型的星型数据库设计,一个事实表包含按产品、地区和时间段排序的销售数据。
Catalog statistics can become stale over time as changes to the table and the data occur.
一段时间之后,随着表和数据发生更改,目录统计信息可能会过时。
We also showed how each time the table is refreshed, a recreated data provider is assigned to the table.
我们还展示了在每次刷新表之后,如何给表分配重新创建的数据提供程序。
A table that includes temporal data has a pair of date-time columns that indicate the period (the time interval) when the row is valid.
包含时态数据的表有两个日期-时间列,它们表明每一行有效的期限(时间间隔)。
When the data has just been moved into that table, it contains in our scenario information that is no more than an hour old, plus a small delta corresponding to the time required to execute the step.
在本场景中,当数据刚刚被移到该表中时,它包含的信息要少于一个小时的,因为执行该步骤所需的时间导致了很小的时间差量。
If the sorted data cannot fit entirely into the sort heap, which is a block of memory that is allocated each time a sort is performed, it overflows into a temporary table owned by the database.
如果无法将排序的数据整个放入排序堆中(排序堆是每次执行排序时分配的一块内存),它就会溢出到该数据库所有的临时表中。
Includes a high-availability data replication (HDR) feature for disaster recovery and continuous log restore, point-time instance-wide restore, and table-level backup and recovery.
内含高可用性资料抄写 (HDR)功能,以便提供灾难回复与连续记录还原、时间点实例层面还原、表格层次备份及回复。
The same is true for retrieving data; every time you retrieve data from the ORDER_ITEMS table, you also want to get the order information, so order table will be accessed too.
对于抓取数据也是一样;每当从order_items表抓取数据时,还需要获取订单信息,因此还要访问order表。
First, the Vee-Table pointer is used to access virtual functions, and data members are accessed directly using compile time offsets.
首先,Vee -Table指针用于访问虚函数,而对数据成员的访问直接使用编译时偏移量实现。
This article describes a generic way to access data using the Open SQL interface in which the actual data to be retrieved from a single table or a number of tables is specified at run time.
本文介绍一种使用OpenSQL接口访问数据的通用方法,这种方法从在运行时指定的一个或许多表中获取实际数据。
For example even though at design time a variable of data type double can be mapped to a table column of type XML, the run time consequences are unpredictable and hence resulting in errors.
例如,虽然在运行时可以将double类型的变量映射到xml类型的表列,但是这可能导致不可预测的运行时结果,并因此而产生错误。
The LiveGrid in Figure 1 is a scrollable table of information where the data in the table is updated on-the-fly each time the user clicks on the scrollbar.
图1中的 LiveGrid是一个可滚动的信息表,每当用户单击滚动条,表中的数据就动态更新。
