  Hi, this is funny.

  I got Execute SQL Task with SQLStatement as stored procedure; also I have Result Set configured there. I created package variable of 'DBNull' data type to handle result set (and pass it into Foreach Loop Container as a next step). Testing Execute SQL Task itself and getting error 'the type of the value (DBNull) being assigned to variable differs from the current variable type (DBNull)'. Data type is equal! What the thing? Please advise.

  You need to use a data type of Object to handle resultsets.

  Thanks Phil Parkin, it works fine with variable of 'Object' data type.

  I must say, error text is not intuitive at all.

  I'm with you on error message clarity. On Azure, I'm currently dealing with this one, so count yourself lucky!

  Thanks Phil Parkin again. I'm not big fan of Microsoft products in general. Just open to work with any type of database. SSIS usage is just side effect of my current project.
