Procedures with more than 1 command not supported

Example:

CREATE DEFINER=`root`@`%` PROCEDURE `testproc`()
BEGIN

Truncate Table testable;
Select * from testable;

END

Calling this procedure causes:
Error Code: 1178. The storage engine for the table doesn't support This stored procedure syntax is not supported by Columnstore in this version

And this happens with all columnstore procedures having more than 1 command
