Recommended Posts

Hi all ! Can you help me please with the elevator system, when I make the first position of the elevator in the second position it gives me this error! how can i solve

If you search for the error string and go backwards, you'll find it's triggering condition is id being false, and id is defined as the return of SmallestElevatorID(). This means that function failed to return a correct value. So let's look at the function

function SmallestElevatorID( ) -- finds the smallest ID in the SQL instead of auto increment
	local result = mysql:query_fetch_assoc("SELECT MIN(e1.id+1) AS nextID FROM elevators AS e1 LEFT JOIN elevators AS e2 ON e1.id +1 = e2.id WHERE e2.id IS NULL")
	if result then
		return tonumber(result["nextID"])
	end
	return false
end

My bet is you either don't have the mysql resource, or it's not running, or it's misconfigured or not connected to a db server, or you don't have the elevators table in your database, or its structure is wrong.

Did you check /debugscript 3
