Thread: Correct way to send a composite type to Postgres

I have a composite type that is an IN parameter for a Stored Function.  How do I construct the type in Java?

I know in Postgres I can do row(...)  I was hoping for something a little more Javaish instead to having to build that String.

Can I extend PGObject to accomplish this?

Thanks,

Currently there isn't a great way to do this with the PG JDBC driver.  You
can encapsulate the ugliness with PGObject, but you can't avoid it.  If
you have a type that extends PGObject all you need to do is override the
toString method to format the data as the server expects it.

yea that is what i did.  I was wondering though if there are gotchas here for escaping?  Are here are Utilities in the driver I can use to make sure the data is escaped ok?  any thoughts here. 

I mean basically i did

public String getValue() {
        return "(" + person.getId() + "," + person.getFirstName() + "," + person.getLastName() + "," + person.getMiddleName() + ")";
}
