JDBC Type 0 not yet supported

[WhyDontYouSlide]

Hey all,

I would like to share you guys this problem im getting constantly by using
Ibatis via jdbc to do queries on DB2...

Let's say we have written a simple query like this

SELECT  PCT_SCO_MAX,           
       FROM    $schema$.FLES_PERC_SCO
       WHERE   COD_COMPANY      = #codCompany#
             AND  COD_SELLER     = #codSeller#  

the JDBC drivers via Ibatis framework CANNOT map a EMPTY STRING value into
"codSeller"
infact it maps "null"  as you can see in the log:

DEBUG [java.sql.PreparedStatement]--<{pstm-105524} Parameters: [112, null]>

but this way makes your query NOT fetch any results...

So i've rounded the problem witha /dynamic TAG but this solution is not
stylish ;-)

<dynamic>
               <isNotEmpty prepend="AND" property="codSeller">
                       COD_SELLER     = #codTipoUnita#                     
                </isNotEmpty>
                <isEmpty prepend="AND" property="codSeller">
                       COD_SELLER     = ' '                    
                </isEmpty>
</dynamic>

someone got a better idea???

thx

WDYS
