There is a database table named Department containing a column named deptname.
这是一个包含 deptname列的名为Department 的数据库。
In this case, there are two column groups: (deptno, deptname) and (admrdept, location).
本例中,总共有两个列组:(deptno,deptname)和(admrdept,location)。
Under the Result Attributes tab, deselect all attributes except "deptname" and "deptno."
在标签ResultAttributes之下,取消对除“deptname”与“deptno”之外所有属性的选择。
Example 18: Collect catalog statistics on all indexes and on columns deptno and deptname.
示例18:收集所有索引以及列deptno和deptname上的目录统计信息。
Example 17: Collect catalog statistics on all indexes and on column deptname with distribution.
示例17:收集所有索引上的目录统计信息,包含列deptname 上的分布统计信息。
Example 16: Collect catalog statistics on table, with distribution statistics on columns deptno and deptname.

Distribution statistics limits are set individually for the deptname column, while deptno column USES a common default.
单独为deptname列设置分布统计信息的范围,而deptno列使用公共的默认值。
Example 12: Collect catalog statistics on only the table, with basic column statistics for deptno and deptname and distribution statistics on mgrno and admrdept.
示例12:只收集表上的目录统计信息,包含deptno和deptname上的基本列统计信息以及mgrno和admrdept上的分布统计信息。
Note that the DeptName and Location values are only default values that need to be changed using the Edit and Update buttons in the DataGrid, as you can see in Figure 9.
注意,DeptName和location值只是默认值,还需要使用DataGrid中的edit和Update按钮进行更改,正如图9中可以看见的那样。
