Assert failure when concatenating strings with total size greater than 32K
--------------------------------------------------------------------------
Key: DERBY-4793
URL: https://issues.apache.org/jira/browse/DERBY-4793
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.6.1.0
Reporter: Knut Anders Hatlen
Attachments: concat.sql
When concatenating two strings whose total length exceeds the maximum length
for a VARCHAR, an assert is triggered in the debug jars:
ij> values length('0123456789.....' || '0123456789.....');
ERROR XJ001: Java exception: 'ASSERT FAILED The maximum length 35000 for the
result type VARCHAR can't be greater than it's maximum width of result's
typeid32672: org.apache.derby.shared.common.sanity.AssertFailure'.
With non-debug jars, the same query completes successfully:
ij> values length('0123456789.....' || '0123456789.....');
1
-----------
35000
1 row selected
I think this query is supposed to fail, also with non-debug jars, but in any
even it shouldn't be raising assert failures.
