This seems to work just fine.
Thanks. - When I'm using that format string, I get:

I did not write a SELECT statement (see first post of this thread) ...
SELECTs are generated by haskelldb(-hdbc-postgresql)
I have a working version now, but only by

That is exactly the problem - it is wrong for CalendarT.
what do you mean by it ... what package should be fixed
(old-locale, haskelldb-hdbc-postgreqsl, ...)?
Because obviously something seems broken here.

well this wouldn't help in my case since I did not CREATE TABLE

Hello Johannes,
I think you are looking for HaskellDB, you can find it on hackage. I've
been working with it myself and can absolutely recommend it.
It is actively maintained by Justin Bailey.
It's a EDSL for relational algebra which gets translated into SQL. It
can use HDBC for instance as
I think you are looking for HaskellDB,
thanks, I'll look into it.
As with LINQ you need to put an initial effort into describing the
tables [...]
according to the documentation, that's what dbdirect is for?
I see the source, but not how to build it.

can use HDBC for instance as its *driver* to databases supported by HDBC.
ok, so I guess I need haskelldb-hdbc-postgresql
but hdbc-postgresql has build failures

Looks like HDBC-postgresql's Setup.hs needs to be updated to use newer
versions of Cabal properly;
if you're using the latest release of the Haskell Platform [...]
but this would not work with ghc-6.12 ...
Anyway the trick is to remove AnyVersion from Setup.hs (thanks, Michael!)

It's been some time since I last tried HaskellDB

I get this when executing a query via haskelldb-hdbc-postgresql-0.12
