  Function   : 寫一支通用 orm-api 依傳入的參數及設定, 智慧的組出相應的 sql
               MariaDB 版本
  
  Description: 本程式是想模仿 orm 的設定, 然後讓前端程式只要傳入參數, 就能執行 orm 的增刪查改的基本功能
               R(Read) 是讀取單筆資料, p_paras 的參數內容同 CU >> 取消不用
               P(Page) 是以頁為單位的讀取模式, 一般是 cowork with DataGrid
               
               呼叫 api 範例如下
               --新增資料

               CALL orm_api_v2('token_value','basarea','areaid','D','')  --刪除資料

               -- 新增 Query 後要分頁顯示(擴充 P 的功能, 多傳 wheresql)
