select without from

[Daniel]

As part of a locking table, I'm trying to execute:

select now(); 

in Postgres in order to use the DB as a synchronized time source. I can't figure out from the docs or examples a way to create a select statement without a table. Is this supported? Is there something simple I'm missing?

I can't think of a way to do this with Squeryl, but I also can't see how Squeryl would help much with a query like this.  Squeryl's strength is in maintaining type safety when your SQL maps to Scala objects.  Since that's not the case here, you're probably better off just using straight JDBC.
