String no longer works in query when column type is Integer
-----------------------------------------------------------
Key: CAY-1298
URL: https://issues.apache.org/jira/browse/CAY-1298
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0 beta 1
Environment: IcedTea6 1.6.1
PostgreSQL 8.3
JDBC 8.3-603.jdbc4
Reporter: Dave Dombrosky
Priority: Minor
I have queries that no longer work in 3.0B1, because of a change that was made
in revision 813661. For example, a query like this used to work:
DataObjectUtils.objectForPK(db, Artist.class, "1");
But now, I get the following error:
org.postgresql.util.PSQLException: ERROR: operator does not exist: smallint =
character varying

The strange part is that the logger shows the query as SELECT t0.name, t0.id
FROM lookup.color t0 WHERE t0.id = ? [bind: 1->id:'1'], both before and after
the change. Postgres can usually deal with using a character type to match on
an integer column. Something must have changed with the JDBC binding that is
not showing up in the textual representation of the query.
