WSO2 Update SQL Query with optional parameters - wso2

Question

I'm writing a sql update query. I have tried to do it both in DbReport and in DataService.
The table has 5 fields (the id + 4 more) and if I only want to update the first parameter, the others will set to null in database.
Example:
Url --> http://localhost/myservice?id=xxx
Body ( only sent "param_1" value:
{
"body":{
"PARAM_1": 1670217
}
}
DataService
<operation name="updateRecargasById">
<call-query href="updateRecargasById">
<with-param name="PARAM_1" query-param="PARAM_1" />
<with-param name="PARAM_2" query-param="PARAM_2" />
<with-param name="PARAM_3" query-param="PARAM_3" />
<with-param name="PARAM_4" query-param="PARAM_4" />
<with-param name="ID" query-param="ID" />
</call-query>
</operation>
<query id="updateQuery" useConfig="configDS">
<sql>UPDATE TABLE SET PARAM_1 = :PARAM_1, PARAM_2= :PARAM_2, PARAM_3= :PARAM_3, PARAM_4= :PARAM_4 WHERE ID</sql>
<param name="PARAM_1" ordinal="1" paramType="SCALAR" sqlType="STRING" optional="true" type="IN" />
<param name="PARAM_2" ordinal="2" paramType="SCALAR" sqlType="STRING" optional="true" type="IN" />
<param name="PARAM_3" ordinal="3" paramType="SCALAR" sqlType="STRING" optional="true" type="IN" />
<param name="PARAM_4" ordinal="4" paramType="SCALAR" sqlType="STRING" optional="true" type="IN" />
<param name="ID" ordinal="5" paramType="SCALAR" sqlType="STRING" type="IN" />
</query>
Sequence
<dataServiceCall serviceName="updateDS">
<operations type="single">
<operation name="updateQuery">
<param evaluator="xml" expression="$body//PARAM_1" name="PARAM_1"/>
<param evaluator="xml" expression="$body//PARAM_2" name="PARAM_2"/>
<param evaluator="xml" expression="$body//PARAM_3" name="PARAM_3"/>
<param evaluator="xml" expression="$body//PARAM_4" name="PARAM_4"/>
<param evaluator="xml" expression="get-property('uri.var.id')" name="ID"/>
</operation>
</operations>
<source type="inline"/>
<target type="body"/>
</dataServiceCall>
Is there any way to write this query to set only the fields setting in the request body?
Kind regards!!
