RE: How to use type handler callbacks inside quiries?

[Jean-Francois Poilpret]

Not sure I understand _exactly_ what you want, so just in case:   Did you try <typeHandler javaType="MyTpe" callback="MyTypeHandler"/> It works very well for me (as long as you have defined a TypeHandler for a specific class type of your own). It is documented in the wiki:   http://opensource.atlassian.com/confluence/oss/display/IBATIS/How+do+I+use+a+Custom+Type+Handler+with+complex+property+or+Type+Safe+Enumeration%3F   Cheers               Jean-Francois   From: Zeltner Martin [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 05, 2005 1:13 PM To: 'user-java@ibatis.apache.org' Subject: RE: How to use type handler callbacks inside quiries?   Once again.   How does I have to use TypeHandlerCallbacks inside the #myProperty#? I DON'T want to use a separate parameter maps only because I'm needing a type handler for one column!   Thanks for your help in advance!   Cheers, Martin    -----Original Message----- From: Clinton Begin [mailto:[EMAIL PROTECTED] Sent: Dienstag, 5.

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!  ;-) Clinton On 7/4/05, Daniel Henrique Ferreira e Silva <[EMAIL PROTECTED]> wrote: 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.
