构建散列表时，连接键被下推用于过滤事实表的行，性能也显著提高。
When hash tables are built, join keys are pushed down and used to filter the rows of the fact table, and performance improves dramatically.
如果您所使用的键不能用来确定哪一行是在先，那么它也可以解决这类平局问题。
It can also resolve ties that happen when the keys you used cannot be used to decide which line is first.
注意，这假设从不更新键列；一旦一行存在了，它的主键值就不变了。
Note that this assumes that key columns are never updated; once a row exists, it is immutably tied to its primary-key value.

分区键是用于确定特定一行数据存储在哪个分区的一个列(或一组列)。
A partitioning key is a column (or group of columns) that is used to determine the partition in which a particular row of data is stored.
如这个查询计划所示，不止一个散列表的键可以被下推来过滤事实表的行。
As this query plan shows, keys from more than one hash table build can be pushed down to filter rows of the fact table.
这个键组合了多列，唯一地定义一个数据库表的行。
This is a key that combines a number of columns to uniquely define the rows of a database table.
在使用DPF时，根据表的分布键(这在创建表时定义)的散列值，把表的每一行放在特定的数据库分区中。
With DPF, each row of a given table is placed in a specific database partition based on the hashed value of the table's distribution key, which is defined when the table is created.
如果您省略了第二个数字，那么sort会假定键是从给定的字段开始，一直到每一行的末尾。
If you omit the second number, sort will assume that the key starts at the given field and continues to the end of each line.
要定义组合键，只需从该领域中选择一些属性，并将其组合在一起，提供所需的行唯一性程度。
To define a composite key, you simply take some attributes from the domain and combine them to provide the required degree of row uniqueness.
Time维度表中满足过滤条件的 time_id连接键被散列以创建一个位向量，用于过滤以上跳跃式扫描的Orders 表行。
The time_id join keys that meet the filter requirements on the Time dimension table are hashed to create a bit vector that filters rows of the Orders table from the skip scan above.
键之间的连接行已经没有了，因为现在关系已经是一个复杂的表达式，而不是在查询主题之间连接项目那么简单。
The link line is no longer there between the keys since the relationship is now a complex expression that goes beyond linking items from one query subject to another.
最小的表首先被扫描，然后哈希表被填入相匹配的每个键的行指针。
The smallest table is scanned first, and the hash table is populated with Pointers to the rows that match each key.
如果要选择多列，在单击其他列的行选择器时按住ctrl键。
If you want to select multiple columns, hold down the CTRL key while you click the row selectors for the other columns.
向上键：将内容向上滚动一行。
例如，在我们的应用程序中，标准错误信息将显示在消息行中，正好在屏幕下部的功能键显示区之上。
For example, in our applications, the standard error message will be displayed in the message line, just above the function key line in the lower part of screen.
Eclipse提供了一个方便使用的快捷键可以简化此操作：按ctrl +e组合键，然后将在选项卡行中的右上角显示弹出式菜单并列出所有打开的编辑器(参见图2)。
Eclipse has a nice shortcut that makes this easier: press Ctrl + e, and a pop-up menu appears at upper right in the row of tabs and lists all the open editors (see Figure 2).
行的键是文档的ID；值就是文档本身。
The key of the row is the ID of the document; the value is the document itself.
实际的比例取决于事实表中带有下推键的行的分布。
The actual proportion depends on the distribution of rows with the pushed-down keys in the fact table.
默认情况下，用于在历史中移动并编辑行的键和键组合类似于gnuEmacs编辑器中使用的相应内容。
By default, the keys and key combinations used to move through the history or edit lines are similar to those used in the GNU Emacs editor.
为下一个记录添加一行，按下回车键，或者右键单击最后一个记录并且选择AddRecord。
To add a line for the next record, press Enter or right-click on the last record and select Add Record.
如果会话已存在，第7行代码将从会话中获取会话键，否则它将为null。
Line 7 gets the session key from the session if it's already present, else it would be null.
包含清单第3行的循环将遍历接收到的键，获得相应值，并把它作为数组或字符串输出。
The loop including line 3 of the listing is working through the keys received, getting a corresponding value, and printing it as an array or a string.
在满足筛选器条件的每个行中，数据库服务器将对键应用哈希函数，并探测哈希表以查找匹配的键值。
For each row that satisfies the filter condition, the database server applies hash function to the key and proves the hash table to find a match.
