二次开发模块
一、条形码的批量生成,
款式:由存货(7)+颜色(2)+尺码(2)+供应码(2)+年份(4)+月份(2)+流水号(6)自由组合生成
面料:由存货(7)+颜色(2)+供应码(2)自由组合生成
(1)由于每件款式的条码是唯一的,其数据量相当大,在数据库存储方面若按以往的方式处理,估计数据库是无法承受。故需采用新的存储方式,在这存储方面就需花较多的时间方可解决。
(2)条码生成后需同时往用友数据库(表:InventoryBarCodeSet)插入数据,以供用友制单时提供对应关系。
-Secondary development of one module, the bulk barcode generation, styles: from inventory (7)+ Color (2)+ Size (2)+ Supply code (2)+ Year (4)+ Month (2) 2B ! serial number (6) to generate ensembles of fabrics: from inventory (7)+ color (2)+ supply code (2) free combination to generate (1) as a result of each style of bar code is the only, the amount of data quite large, if the database storage means in accordance with the previous treatment, it is estimated that the database is not unbearable. Therefore need to adopt a new way of storage in this storage area on the need to spend more time in order to resolve. (2) bar code generated at the same time after UFIDA to database (table: InventoryBarCodeSet) Insert the data for single-UF s
