1.1 功能说明
一般来说我们会先有一个老的文件这个文件内容是定制好相关列的表格作为每天的报告。 当下一天来的时候需要根据新的报表文件和昨天的报表文件做一个合并合并的时候就会出现有些事新增条目、有些是可能要删除的条目、有些是要更新状态的条目。 当前使用python编写的练习就是达到这个简单目的。
1.2 配置文件
配置文件内容样例
yesterdayF:\projects\daily_merge_tool\test_files\scene1_no_diff\yesterday.xlsx
todayF:\projects\daily_merge_tool\test_files\scene1_no_diff\today.xlsx
reportF:\projects\daily_merge_tool\test_files\scene1_no_diff\report.csv
yesterday_primary_key_columnD
yesterday_status_columnE
today_primary_key_columnF
today_status_columnE
today_mapping_yesterdayC:B,D:C,F:D,E:E,H:F,I:G,J:H,K:I,L:J,M:Kyesterday的值为昨天的报表文件绝对路径 today的值为今天从其他系统新导出来的报表文件的绝对路径 report的值为存放合并当天最新报表的csv文件的绝对路径 yesterday_primary_key_column的值为昨天的报表文件中能够唯一代表一行数据的属性所在的列例如如果值是字母A是excel表格的第一列 yesterday_status_column的值为昨天的报表文件中当前行数据的状态列例如如果值是字母A是excel表格的第一列 today_primary_key_column值为今天的报表文件中能够唯一代表一行数据的属性所在的列例如如果值是字母A是excel表格的第一列 today_status_column的值为今天的报表文件中当前行数据的状态列例如如果值是字母A是excel表格的第一列 today_mapping_yesterday的值为昨天报表文件中各个列的数据来源映射到今天新导出的报表文件中的列
1.3 几个文件的样例
yesterday.xlsx today.xlsx 生成的report.csv相比yesterday.xlsx增加了1列Tag标示当前行是新加还是修改了状态还是确认是否要删除
