New Method for the User to Set the Computational Relation in Report Flexibly by Using PB

介绍了如何在应用程序中,实现用户灵活设置报表数据项及计算关系,利用PB语言,由数 据项定义自动增加后台表列,由计算关系自动生成对应SQL语句,从而实现根据用户在报表中录入的 基础数据自动求得结果。

This paper introduces a new method for the user to set the data item and computational relation flexibly in the application program. By using PB language, the table column of backgroud is automatically added by the definition of data item, and the corresponding SQL statement is automatically generated according to the computational relation.
