How to use type handler callbacks inside quiries?

[Zeltner Martin <ma...@elca.ch>]

Hi,

How does I have to declare type handler callbacks inside #myData#?
I can not use a parameter maps, because my statement contains dynamic parts.

Thanks,
Martin

True Daniel,

It's possible. But I do sympathize with Marting, as it currently is a pain 
in the butt. 

The biggest issue is that you have to ensure that the parameters line up 
exactly. That is, you need to ensure that all paths of the conditional 
results result in the exact same number and type of parameters.....

The design of parameter maps is shotty at the moment (embarassing for a 3 
year old project).....iBATIS 3.0 (or perhaps even 2.5) will use named 
parameters, much like Spring, O/R Broker and .... even ADO .NET (see, there 
is something to learn from the C# dudes! ;-)

Hi Martin,

Why can't you use a parameter map in a dynamic statement? That _is_
possible in iBATIS. Just check the documentation.

Cheers,
Daniel Silva.
