EBS FORM开发问题总结

1，form是基于单表视图建立的，没有写on-insert此类的触发器。在视图上加了个rownum列结果导致form上的列不能更新

据说此种情形下的form会判断视图上的列是否属于基表，不属于的话会导致整个块不能更新。

2，在form界面上显示行号

在post-query里使用:system.trigger_record;

SYSTEM.CURSOR_RECORD和:system.trigger_record的区别：

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.
