you cant do sp calls in hibernate without serious pain.

it is a superset of mybatis statement mapping, which i thought you enjoyed

alternatively hibernate also lets you just call SPs directly with a single method call and not have any SP mapping poo poo at all, like jdbc, but get back a useful object (in this case a Cat)

Java code:

sess.createSQLQuery("CALL get_cats()").addEntity(Cat.class);

where is the serious pain?

unless hibernate has changed recently it doesn't do statement mapping. mybatis is a completely separate project that was started specifically cause doing procs in hibernate sucked. like you cant do a proc that doesn't return a result set.

also doing sql in code is dumb

if you've got a shitload of money to hire a license consultant and then figure out how many cores are in your servers and sockets and spend like six or seven figures on geospatial support in oracle too

man this is what my company needs to do because every time we set up an oracle spatial database, the performance is terrible and it shits itself on a regular basis. can't do that though because we gotta meet this stupid schedule!!!!

exceptions are part of the interface

if you gently caress with the interface then the users are hosed regardless

# ? Jul 26, 2013 09:57

zokie: Feb 13, 2006; Out of many, Sweden

And then I cant properly handle the exception when initially caught, so I have to break the interface for an arbitrary number of things just because checked exceptions.

# ? Jul 26, 2013 10:06

Workaday Wizard: Oct 23, 2009; by Pragmatica

how will option types solve that?

the user still needs to change their code

the compiler might not complain about it (e.g. they match non-success with underscore) but if they don't change it they'll get undefined behavior

score one for exceptions

It lets them handle exceptions where they find it suitable, and let them decide on whatever they want to do. Instead of forcing them to jump through hoops to make stuff compile. I mean, it's not like they are enforced on the lower levels it's just an annoying gatekeeper. Java does not need them to function!

lesse the option type solution. we have two types of users:
1) users that match against all possible options:
these guys get a compile error (missing case) to modify their code in response to interface change. no improvement over exceptions
2) users that match against success and lump everything else in one case:
these guys don't even get a warning what the gently caress happened. if you throw your new error type in the library they have undefined behavior. (e.g. your library hosed with some stateful thing). worse than exceptions

principle of least astonishment etc etc

if you change the api enough that its returning a new error and you don't do something that's gonna fail to compile, they're never going to know about your change and if it starts loving up return values (ex: returning nothing instead of a value) they're never going to know about it and now you've ruined their application.

although if you think making programmers aware of api error changes is "jumping through hoops" then you probably wont ever get it. having the compiler error cause of new checked exceptions is one of the best parts of checked exceptions.

# ? Jul 26, 2013 14:28

trex eaterofcadrs: Jun 17, 2005; My lack of understanding is only exceeded by my lack of concern.

just version your apis and don't make breaking changes?

sure, but what's a programmer more likely to do when upgrading a library:
1) read the documentation carefully for changes
2) slam it in and mash compile w/out thinking

that sounds like a sum type. an option type looks like this:

code:

data Maybe a = Just a | Nothing

it's a nullable type if null wasn't a terrible hack
