> 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;
