Listing 3.the work items data set including the new computed column.
清单3 .包括新计算列的工作项数据集。
For example, if you have a data set of work items, you can add a computed column that shows the severity.
例如，如果您有一系列的工作项，那么您就可以添加显示严重程度的计算列了。
Describes how to enter a computed column expression and set properties for the column and expression.
说明如何输入计算所得列表达式，以及如何设置列和表达式的属性。
On the computed Columns TAB, add a new computed column with the type String and a name such as Severity name.
对于Computed columns项，添加一个String类型且名为SeverityName的新计算列。
Computed columns use a mathematical or other expression to generate results for a column, optionally using data from other columns.
计算所得列使用算术表达式或其他类型的表达式，有选择地使用其他列中的数据来生成结果。
Add a computed column to the work items data set named "STATE ID" that concatenates the project area name with the STATE_NAME column (see Listing 6). The value for this column might look like this.
向名为“STATEID”的工作项数据集添加一个计算的列，它将下面区域名字与state_name列联系起来(参见代码清单6)。
The amount of each order is computed by summing the amount column of the associated details records.
每项订单的数量都通过加总相关详细信息记录的列计算得出。
Follow the same process as previously to create a column for the number item. This time the script for the computed field is as follows.
通过与前面一样的过程，为number项创建一个列。
If more than one column is aggregated using the same grouping key or without a grouping key, then all the aggregations are computed within the same operation with a single pass over the data.
如果利用相同的分组关键字或者没有分组关键字，来聚合多个列，那么，所有的聚合都在单个数据传递中的相同操作中进行。
Finite elastic deformation analysis of a four column supported prestressed latticed shallow shell roof shows that the bolts have influence upon the computed results more significantly.
