WSO2 Data Services Server error calling stored procedure - jdbc

Question

I have been able to successfully call a Microsoft SQL Server stored procedure from WSO2 Data Services Server (DSS) and return results. However, getting result sets back from certain stored procedures results in a com.microsoft.sqlserver.jdbc.SQLServerException: This operation is not supported. After some experimentation, I found at least one criteria that results in this error. That is when I create a temp table within the stored procedure. My guess is that this is resulting in a type of result that the DSS code is not expecting or not handling correctly.
The Microsoft SQL Server driver jar file I am using is from sqljdbc4.jar that is part of the August 2015 release of Microsoft JDBC Driver 4.2 for SQL Server. The SQL Server version is SQL Server 2012 (11.0.5582.0).
The example stored procedure I created to reproduce this case is as follows:
CREATE Proc [dbo].[example_proc]
(
#id varchar(255)
)
AS
BEGIN
Create table #temp
(
command_name varchar(50),
transactions int,
timeouts int,
errors int
)
insert into #temp values ('abc', 5, 10, 25)
select command_name, transactions, timeouts, errors from #temp
drop table #temp
/*
select 'test' "command_name", 5 "transactions", 10 "timeouts", 25 "errors"
*/
END
The sample configuration for the data service is as follows:
<data disableStreaming="true" name="MESCDataService" transports="http https">
<config enableOData="false" id="MESCDataSource">
<property name="carbon_datasource_name">MESCDataSource</property>
</config>
<query id="test" useConfig="MESCDataSource">
<sql>{ call dbo.example_proc (?) }</sql>
<result element="Results" rowName="Result">
<element column="test_column" name="TestColumn" xsdType="string"/>
</result>
<param name="val" sqlType="STRING"/>
</query>
<operation disableStreaming="true" name="test">
<call-query href="test">
<with-param name="val" query-param="val"/>
</call-query>
</operation>
</data>
The configuration for the Carbon Data Source is:
Driver: com.microsoft.sqlserver.jdbc.SQLServerDriver
URL format: jdbc:sqlserver://[hostname]:[port];databaseName=[dbname];
Here is the excerpt from the wso2carbon.log file with more details on the error:
