title: Checking SSIS variable of Object data type for NULL Value
body: <p>everyone,
  In my SSIS package, I have a variable FilesInfo of Object data type that gets its values from the Full Result Set from  an Execute SQL task, which may or may not return any results. I have a Foreach loop container to do further processing.  If the values are not null, the package executes successfully. However, it throws an error when nothing returned fromthe SQL task.
  To fix this, I want to add a Precedence Constraint to direct the flow only when FilesInfo is NOT NULL. Is there a way to do it? And if so, what is the exact syntax?
  Thank you for your help in advance.
  Regards</p>
