ABAP如何判断一个变量是否存在于一个内表中? if cinfo-gh IN i_gh.这么写不行

如果是一个内表的话， IT_TAB， 那么假设这个字段是 ZIDUAN.

sort IT_TAB by ZIDUAN.
read IT_TAB with key ZIDUAN = 'bianliang' binary research.
if sy-subrc = 0.
则存在。
endif。追问

还是不行。 READ i_delinfo WITH KEY GH = cinfo-GH binary research.
IF SY-SUBRC 0.
DELETE FROM zinfotab WHERE gh = cinfo-gh.
ENDIF.

DELETE FROM zinfotab WHERE gh IN i_gh.你可以直接删除你想删除的.本回答被提问者采纳

看你的代码是不是想把GH=cinfo-gh的记录删掉？如果是那样，直接
　loop at i_delinfo where GH = cinfo-GH .
DELETE GH = cinfo-GH .
endloop.
不就完了？
