#nco3

是咁的, sap 的世界, 網上既資料好凌散, SNR 極低. 有見及此, 我黎緊就嘗試將呢d 有用既整理下, 希望諸君同我都有用, 齊齊發SAP財. 第一炮, 係關於so called sap .net connector (nco3). 唔知點解佢果d tutorial 呀, official 既書 都寫得唔到point. 點唔到point? 其實用得nco3 有一個好major既原因, 就係將nco2 d code轉成 nco3 既寫法.唔知點解, 無人比較過. SAP既community好奇怪, d 人答野好冗長, 一係得code, 一係答非所問. 以下係本人對nco2 同nco3 syntax既濃缩版.
