DB2 - Problembeschreibung

Problem IC89081 Status: Geschlossen

DIFFERENT BEHAVIOUR IN DB2 WHEN USING ORACLE SYNTAX "CONNECT BY
NOCYCLE LEVEL"

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
An example SQL: 
---------------------------------------------------------------- 
SELECT LEVEL FROM DUAL CONNECT BY NOCYCLE LEVEL <= 10 
---------------------------------------------------------------- 
 
Since the virtual table DUAL has 1 row, the intermediate result 
table Hn+1 would return the same row as the one that is already 
in the hierarchical path. According to the documentation, the 
NOCYCLE keyword will not include the repeated row. This is an 
intended behaviour in DB2, which is different from Oracle 
behaviour.
