Hi,

can someone please point me to error handling examples with takusen?

I try to run a piece of code with takusen but just get the very sparse "Database.InternalEnumerator.DBException

Hello Günther, We use dynamic exceptions in Takusen, which is why you don't get much useful information when an exception is thrown. We will include the new extensible-exceptions code in the next release, so once that it done perhaps we can change the way we do exceptions so that you get better messages by default. There are some basic exception handling functions in Database.Enumerator which should help. Firstly, you need to add an exception handler with catchDB. Then you can choose to ignore the error, report it, or re-raise it (see basicDBExceptionReporter and reportRethrow). Also, the DBException constructors are exported, so you can pattern match on it to extract more information, like SqlState, error number, and error message. Alistair
