Subject RE: Need help---Mapping of Complex properties
Date Fri, 28 Jul 2006 08:25:21 GMT

Hi Aram,
Thank you for your reply. I found the exact problem. Can you please help
me now.?

The following query is working if the user is having exactly one user
properties record.
Here the User is master table and Properties is detail table.

<resultMap id="userMapForStaticAndDynamicRamBabu" class="user">
<result property="userid" column="USR_ID"/>

<result property="role" column="ROLE_ID"/>

<result property="description" column="DESCRIPTION"/>

<result property="properties" column="USR_ID" select="RamBabuExtension"
/>

</resultMap>

<resultMap id="userExtensionMapForStaticAndDynamicRamBabu"
class="iBatisDynamicProperty">

<result property="userid" column="USR_ID"/>

<result property="propertyname" column="PROPERTY_NAME"/>

<result property="propertyvalue" column="PROPERTY_VALUE"/>

</resultMap>

<statement id="RamBabu" resultMap="userMapForStaticAndDynamicRamBabu">

     select * from USR_BASIC_INFO

</statement>

<statement id="RamBabuExtension"
resultMap="userExtensionMapForStaticAndDynamicRamBabu">

   select * from USR_EXTENSION_INFO where USR_ID=#userid#

</statement>

If the second select query(select * from USR_EXTENSION_INFO where
USR_ID=#userid#) returns multiple results then
it is throwing the following error.
Check the User.userMapForStaticAndDynamicRamBabu.

--- Check the result mapping for the 'properties' property.

--- Cause: java.sql.SQLException: Error: executeQueryForObject returned
too many results.

we are getting this error because the second query is returning multiple
results. If only one record per user is there then there
is no issue. So can you please look into this.

So some where i have to change to List, this is i am not getting where
to change.
Any way thanks a lot Aram.

I have get and set methods for the properties attribute. The paramater
for the set method is iBatisDynamicProperty
which is specified in the resultMap.

regards,
Rambabu

<result property="properties" column="USR_ID" select="RamBabuExtension"
/>



You missed also column attribute.

Also use USR_ID=#value# instead of USR_ID=#usr_id#

Add this and try again.



Best,

Aram
