Trouble inserting data into an sqlite3 database

[PureTryOut]

I'm not sure what really changed, but I can succesfully create tables and insert data now. My code however, is practically the same. I really don't know, but I guess fixed

Anyways I managed to retrieve some data from the database, however it gives an error if the result is empty. So for example I have:

Code:

SELECT * FROM test WHERE test_id = ?

If the ID I'm asking for does not exist, then I get the following error:

Code:

[17:13:55] LUA: Plugins/Townvalds/database.lua:43: misuse of function
[17:13:55] Stack trace:
[17:13:55]   [C](-1): get_values
[17:13:55]   Plugins/Townvalds/database.lua(43): ExecuteStatement
[17:13:55]   Plugins/Townvalds/functions.lua(48): (no name)
[17:13:55] Stack trace end
[17:13:55] Error in plugin Townvalds calling function <callback>()

If the ID i'm asking for however does exist, then I have no problems whatsoever.
I'm using "stmt:get_values()" to retrieve the data from the query.

It's more of a general Lua question, but I'm guessing you guys will have a clue
