Question

I am trying to convert a normal STP to a partially dynamic SQL I need the dynamic part to set value to a parameter, which I would later use in my non-dynamic part of the STP.

when I print it in the inside of the dynamic @stmt it’s OK but outside it is empty

what am I missing?

————————————————————–constructing statement

set @stmt = 'set @stringActors = cast((select actors.actor_id     '+@from_clause+' '     +@where_clause+' '     +'for xml raw,type) as varchar(max)) print @stringActors'  print @stmt 

————————————————————–execution

EXECUTE sp_executesql @stmt,N' @stringActors varchar(4000) output ,@user_actor bigint ,@internal_search_actor varchar(30) ,@internal_search_route_manager     varchar(30) ,@internal_search_terminal_id       varchar(30) ,@ACTOR_TYPE_INSTITUTE int  ,@ACTOR_TYPE_LOCATION int' ,@stringActors =@stringActors ,@user_actor=@user_actor ,@internal_search_actor=@internal_search_actor ,@internal_search_route_manager=@internal_search_route_manager ,@internal_search_terminal_id=@internal_search_terminal_id ,@ACTOR_TYPE_INSTITUTE=@ACTOR_TYPE_INSTITUTE ,@ACTOR_TYPE_LOCATION=@ACTOR_TYPE_LOCATION 

—————————————————————–rest of STP (not dynamic) print @stringActors

Answer 1

OUTPUT has to be specified both when declaring and assigning an OUTPUT parameter, so I would say the problem is

,@stringActors =@stringActors ,@user_actor=@user_actor 

should be

,@stringActors =@stringActors OUTPUT ,@user_actor=@user_actor
