1，form是基于單表視圖建立的，沒有寫on-insert此類的觸發(fā)器。在視圖上加了個(gè)rownum列結(jié)果導(dǎo)致form上的列不能更新

? ? ?據(jù)說此種情形下的form會(huì)判斷視圖上的列是否屬于基表，不屬于的話會(huì)導(dǎo)致整個(gè)塊不能更新。

2，在form界面上顯示行號(hào)

? ? ?在post-query里使用:system.trigger_record;? ??

? ?SYSTEM.CURSOR_RECORD和:system.trigger_record的區(qū)別：

? ?SYSTEM.CURSOR_RECORD represents the number of the record where the cursor is located.
??This number represents the record's current physical order in the block's list of records.
??The value is always a character string. ? ?
??SYSTEM.TRIGGER_RECORD represents the number of the record that Form Builder is processing.??
??This number represents the record's current physical order in the block's list of records.
??The value is always a character string.
