[postmodern-devel] A question about connection pooling, and the many ways to connect.
by Jim Barrows 12 Nov '13

12 Nov '13

I'm a java developer, and I think I'm expecting something to happen that's not. In Java I setup a pooled connection, and just use it. The connections pool themselves. I had thought that by doing: (setf *database* (connect "PomBanDone" "pombandone" "pombandone" "localhost" :pooled-p T))) that I would get connection pooling. However now that I'm getting a better understanding of Lisp and I think Postmodern, that connections aren't getting pooled. I think I have to use (with-connection (spec &body body) in order to make the connection pooling work. Is that the case? If not, why would I want to use with-connection? Thanks! -- James A Barrows

What is the easiest way to get the col-type of a slot?
by Sabra Crolleton 08 Sep '13

Feeling a bit brain dead at the moment. I am trying to do a sanity check on user-input before the data gets put in a dao-class. That requires simply checking the col-type for the slot, comparing it to the type for the data and, if they do not match, rejecting the data. I can do it looping through postmodern:dao-column-slots using postmodern::column-type, but is there a way of doing it with exported functions? Sabra
