> I'm not sure if this is ij or derby proper, but the concat operator || should work for
just about any data type.  Derby is zero maintenance, but data rarely is, and a good sql interface
is important.  Often it's very convenient to write a query that generates other sql statements
and that's difficult w/o concatination.
> e.g. create a table with a timestamp column, assume that the column name is originated.
> Try the following query:
> ij> select month(originated) || '-' || year(originated) from review;
> get the following error:
> ERROR 42846: Cannot convert types 'INTEGER' to 'VARCHAR'.
> The conversion to a string should pretty much work all the time unless the operand is
some sort of blob type.
