proc에서..do break가 나오는 현상은 무엇때문이죠??

왜 ..break.에러가 나는지 .....
프로시져에서두 do break.에러가 나오고... 간단한 이것에서두..나오는데..

똑같은 소스를 다른데서 돌리면 되는데....

이런 결과가 나오는데요.. 이것을 본래 작업중이던 곳에 집어 넣으면..

==> 여기에

EXEC SQL WHENEVER NOT FOUND DO break; 이렇게 넣어두.넣지 않아두...
myproc.c: In function `matching_name_index':
myproc.c:980: break statement not within loop or switch
*** Error code 1
이럴때는 어떻게 해야하죠??? 이거 2일째 날새는 건데...

원래는 procedure로 짯었는데..안되어서..cursor 말구..그냥 단순 select로...하려구 하는데.. 원인을 모르겠네요..
