sql/pl正確執行而寫在程序中不能執行

 

SELECT * FROM COMM.COMM_GOODS_CLASS T
START WITH T.LASTCLASSID=0 AND T.ISDELETE=0
CONNECT BY PRIOR T.ID=T.LASTCLASSID AND T.ISDELETE=0
ORDER SIBLINGS BY T.SORT

 上面的sql語句在sql/pl中能夠正確執行，可是寫在程序裏報錯：無效的標識符：COMM'.'T'.'ID'。

發現是沒法識別*。

改爲下面的便可：

 

SELECT T.ID,T.CLASSNAME,T.CLASSID,T.LASTCLASSID,T.LEVELNUM,T.CREATETIME,T.SORT,T.ISDELETE
FROM COMM.COMM_GOODS_CLASS T
START WITH T.LASTCLASSID=0 AND T.ISDELETE=0
CONNECT BY PRIOR T.ID=T.LASTCLASSID AND T.ISDELETE=0
ORDER SIBLINGS BY T.SORT
