Hi
I noticed that all jdbc drivers return the Integer java type for a
SMALLINT database type. Is this intended or is this a bug? The
recommendation in the JDBC book (Hamiltan, Catell, Fisher) says that
SMALLINT should be mappped to the Java short type.
If I want to changes this, is all I have to do is change the line in
/src/interfaces/jdbc/postgresql/jdbc1/ResultSet.java from
case Types.SMALLINT
return new Integer(getInt(columnIndex)
to
case Types.SMALLINT
return new Short(getShort(columnIndex)
?

It's probably been like that since day one. I'll check the specs.

I don't know it's a spec, but the recommendation I have read is in "JDBC
Database Access with Java" - Graham Hamilton - Rick Catell - Maydene
Fisher (The Java Series from the Source) on page 384, and it says:
"The recommended Java mapping for the JDBC SMALLINT type is a Java
short."

I do know that some books have got things wrong (usually typing mistakes
etc).
Anyhow, in the end, the JDBC specification is what counts.
