Stored procedure component

Hello,

I'd like to use the Stored procedure component with an SP that contains dynamic SQL. In fact I create a result set with combined usage of XML Path e Pivot like

User.           Tfr_2013.   TFR_2014    Tfr_2015.   Tfr_2016 .............

User1.           1345.           1578.           1890.          1958

User2.            2345.          3456.           4589.           5678

Where first column and at least one other column are  mandatory, but I  can't definitely know in advance the real number of column. As SP Component needs output parameters coupling, I suspect that it is necessary to create a Custom Component.

Someone had a similar problem or has a bright idea .

Thanks
