Re: [Haskell-cafe] HaskellDB Convertible Exception: incompatible types
Hi, going deeper i found the following: http://hackage.haskell.org/packages/archive/haskelldb-hdbc/2.1.0/doc/html/src/Database-HaskellDB-HDBC.html#line-126 HaskellDB is converting from SqlTimestampT (no timezone defined) to CalendarTimeT (timezone required). This conversion tries then to be done using LocalTime ( http://hackage.haskell.org/packages/archive/HDBC/2.2.6.1/doc/html/src/Database-HDBC-SqlValue.html#line-735 ) which fails. I believe real problem is CalendarTimeT. SqlTimestampT clearly doesn't define a timezone. There's a need to create a new type to handle these types. Timestamps but no timezone (Localtime). I attach a patch for this. I tested this in a project. Not quite sure how to add the tests. What should i do to add this patch to haskell? A version dependency of this two should be added, Andras 2012/9/29 Andras Gyomrey lgand...@gmail.com Hi, I get *** Exception: Convertible: error converting source data SqlLocalTime 2012-04-27 10:22:15 of type SqlValue to type Data.Time.LocalTime.LocalTime.ZonedTime: incompatible types when i try to show a record with a field of type CalendarTime (automatically generated by Database.HaskellDB.DBDirect, Mysql database type is timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP I already looked forhttp:// haskell.1045720.n5.nabble.com/programmatic-DB-interface-td3120759.html. But the problem there is about a regexp (not a type). And the incompatible type problem was caused because of a concatenation. Here, as you can see, i have no idea what's going on. Can someone please help me?

[Haskell-cafe] HDBC nested withTransaction
Hi, are there any plans of implementing nested transactions using withTransaction in HDBC? In mysql exists checkpoints and in postgres explicit subtransactions, Andras Gyomrey ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
