db2 case when和oracle兼容问题

create view VDA_BORROWDISPLAY

(arid,arname,arcode,

createdate,keyword,orgid,

orgname,archivepropertype,archiveproid,

secretlevel,storeterm,

cabcode,facecode,gridcode,

boxcode,layercode,storename,

colcode,isdel,isDisplay)

as

select c.ID arid,c.name arname,c.code arcode,

c.create_date createdate,c.keyword keyword ,organ.organid orgid,

organ.organname orgname, archivepro.name archivepropertype,c.archive_pro_id archiveproid,

enum.name secretlevel,enum1.name storeterm,

cab.code cabcode,face.llabel facecode,grid.code gridcode,

box.code boxcode,layer.code layercode,storehouse.name storename,

col.code colcode,c.isdel isdel,

case

when c.id in (select b.archive_id

from tda_borrow_list a, tda_borrow_detail b

where a.id = b.borrow_list_id

and a.return_date is null) then

'0'

else

'1'

end as isDisplay

from tda_archive c

left JOIN TORG_ORGAN organ ON c.org_id=organ.organid

left JOIN TDM_ENUMITEM enum on c.secret_level=enum.enumid

left JOIN TDM_ENUMITEM enum1 on c.storeterm_id=enum1.enumid

left JOIN TDA_PLACE place on c.place_id=place.id

left JOIN Tda_Col col on col.id=place.col_id

inner JOIN tda_archive_pro archivepro on c.archive_pro_id=archivepro.id

inner JOIN Tda_Cabinet cab on cab.id=place.cabinet_id

inner JOIN Tda_Face face on face.id=place.face_id

inner JOIN Tda_Grid grid on grid.id=place.grid_id

inner JOIN Tda_Layer layer on layer.id=place.layer_id

inner JOIN Tda_Box box on box.id=place.box_id

inner JOIN Tda_Store_House storehouse on storehouse.id=place.store_house_id

以上是视图 该视图在oracle上可以 db2上报错

具体问题如下：

16:43:52 [CREATE - 0 row(s), 0.000 secs] [Error Code: -115, SQL State: 42601] [SQL0115] Comparison operator IN not valid.

... 1 statement(s) executed, 0 row(s) affected, exec/fetch time: 0.000/0.000 sec [0 successful, 0 warnings, 1 errors]

急啊！求朋友帮忙解决下！
