Yes, that I know. I bind several different items.

but the scenario is after some processing I get some value / nodes which I
need to bind to execute query.
in this case, I didn't get any value / node.
Still I need to run the query.

declare variable $a external;
return empty($a)

Query is generated dynamically, variable is defined but for $a I didn't get
any value.
So, I am unable to bind it.
and that's why I getting an error.
