Comparison does not perform implicit type conversion
----------------------------------------------------
Key: DERBY-113
URL: http://nagoya.apache.org/jira/browse/DERBY-113
Project: Derby
Type: Bug
Components: SQL
Reporter: Jeremy Boynes
The operands to a comparision operator are not implictly converted to the
dominant type resulting in an unexpected exception:
For example:
ij> select * from dual where '1' = 1;
ERROR 42818: Comparisons between 'CHAR' and 'INTEGER' are not supported.
fails whereas
ij> select * from dual where cast('1' as int) = 1;

works. The type escalation should be implicit.
