ABAP To the Future 每天练一练1

弄一个标准表试一下 select case

*&---------------------------------------------------------------------*
*& Report ZTESTABAP0001
*&---------------------------------------------------------------------*

*&---------------------------------------------------------------------*
REPORT ztestabap0001.



START-OF-SELECTION.

  SELECT carrid, connid,
  CASE
  WHEN fltime <= 300 THEN 'short'
  WHEN fltime <= 500 THEN 'medium'
  ELSE 'long'
  END AS cityfrom
  FROM spfli
  WHERE carrid = 'AA'
   INTO TABLE @DATA(lt_monsters).



IF sy-subrc = 0.

ENDIF.

再写一段新语法：

  TYPES: l_connid TYPE RANGE OF s_carr_id.


  DATA:lt_connid TYPE RANGE OF s_carr_id.


  lt_connid = VALUE l_connid(
             ( sign = 'I'
             option = 'EQ'
             low = 'L'
*             high = 'M'
             )
             ).


  IF sy-subrc = 0.

  ENDIF.

运行结果
