Structure for 'merge' command - jdbc receiver

Hi All,

In Idoc to Jdbc(receiver) scenario, is it possible to have structure for 'Merge' command? (as we have for insert/update/select/update_insert)

<StatementName1>  

<dbTableName action=”UPDATE” | “UPDATE_INSERT”>

    <table>realDbTableName</table>

<access>

<col1>val1</col1>

<col2>val2new</col2>

</access>

<key1>

<col2>val2old</col2>

<col4>val4</col4>

</key1>

<key2>

<col2>val2old2</col2>

</key2>

</dbTableName>

  </StatementName1>

Like above structure, Please help me on the structure for merge command

Thanks & Regards,
