Problem IC95385

Status: Closed |
DIFFERENT BEHAVIOUR IN DB2 WHEN USING ORACLE SYNTAX "CONNECT BY NOCYCLE LEVEL" |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
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. |
