Specifying an incorrect optimizer property (constraint=null) gives
NullPointerException
----------------------------------------------------------------------------------------
Key: DERBY-1707
URL: http://issues.apache.org/jira/browse/DERBY-1707
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.2.0.0, 10.3.0.0
Reporter: Deepa Remesh
Attachments: illegal_overrides.sql
After we get the NPE, any other operation gives:
ERROR 40XT0: An internal error was identified by RawStore module.
Specifying constraint=null as an optimizer override is actually a usage error.
I tried this thinking it is allowed like index=null which can be used to force
a table scan. But specifying constraint=null gives a NPE and other operations
give the above error. I am attaching a repro 'illegal_overrides.sql'.
Found this when testing with 10.2.1.0 beta. Stack traces below:
ij> --- specifying null value for constraint gives NPE
SELECT * FROM t1 --DERBY-PROPERTIES constraint=null
;
ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
