Subject Re: Need support for Dynamic procedure invocation
Date Tue, 25 May 2010 05:37:21 GMT
I'm not familiar with that class, as it's not part of the framework
(maybe post it here).  Short story is that JDBC requires nullable
column types to be specified.  Ibatis allows for this in the parameter
map (crack open the user guide and search for "jdbcType" for more).

Cheers,
Clinton
