Calculated fields contain a name and an expression 計(jì)算字段包含名稱和表達(dá)式。
Occurs when an application recalculates calculated fields 當(dāng)一個(gè)應(yīng)用程序重新計(jì)算計(jì)算字段時(shí)發(fā)生。
Lesson 11 : creating a calculated field 第11課:創(chuàng)建計(jì)算字段
In addition to database fields , the fields list can contain calculated fields 除了數(shù)據(jù)庫字段之外,字段列表還可以包含計(jì)算字段。
Microsoft project enters certain data into special fields called calculated fields Microsoftproject將某些數(shù)據(jù)輸入名為“計(jì)算域”的特定域中。
It is automatically populated with fields from the query , but you can add additional database or calculated fields the 查詢中的字段將自動(dòng)填充此選項(xiàng)卡,不過,您也可以添加其他數(shù)據(jù)庫或計(jì)算字段。
It also illustrates the use of tables , charts , multivalued parameters , end - user sorting , calculated fields , and drillthrough links 它還說明了表、圖表、多值參數(shù)、最終用戶排序、計(jì)算字段和鉆取鏈接的具體使用。
You can also define additional calculated fields . in summary , each dataset consists of a pointer to a data source , a query , and a collection of fields 這包括設(shè)置與數(shù)據(jù)源的連接,定義查詢,以及定義要在報(bào)表中使用的字段列表。
Calculated fields have expression - based values evaluated when the query runs . you can also create filters to limit the data at the source before it is sent to a report 如果您要改用較為熟悉的圖形查詢?cè)O(shè)計(jì)器,請(qǐng)?jiān)凇皵?shù)據(jù)”視圖工具欄上切換“通用查詢?cè)O(shè)計(jì)器”按鈕。
The methods of gps - data processing and the way to calculate field area using triangle division were put forward in this paper , and the software was programmed to calculate field area through gps 給出了gps數(shù)據(jù)的處理方法,提出了使用三角形分割法計(jì)算農(nóng)田的面積的方法,并編程實(shí)現(xiàn)了農(nóng)田面積的gps測(cè)量計(jì)算。
