If you are using modular Database actions you can turn of the throw of
exceptions:

Here is the config:

   <!-- Modular DB -->
   <map:action name="mod-db-add"
src="org.apache.cocoon.acting.modular.DatabaseAddAction">
          <descriptor>database.xml</descriptor>
          <input>request-param</input>
          <output>request-attr</output>
          <throw-exception>true</throw-exception>
   </map:action>
   <map:action name="mod-db-upd"
src="org.apache.cocoon.acting.modular.DatabaseUpdateAction">
          <descriptor>database.xml</descriptor>
          <input>request-param</input>
          <output>request-attr</output>
          <throw-exception>false</throw-exception>
   </map:action>
   <map:action name="mod-db-del"
src="org.apache.cocoon.acting.modular.DatabaseDeleteAction">
          <descriptor>database.xml</descriptor>
          <input>request-param</input>
          <output>request-attr</output>
          <throw-exception>false</throw-exception>
   </map:action>
