#cs ----------------------------------------------------------------------------
AutoIt Version: 3.3.8.1
Author:		 myName
Script Function:
Template AutoIt script.
#ce ----------------------------------------------------------------------------
; Script Start - Add your code below here
#include <sqlite.au3>
#include <SQLite.dll.au3>
Local $sSQliteDll
Local $hQuery, $aRow, $sMsg
$sSQliteDll = _SQLite_Startup()
If @error Then
	MsgBox(16, "SQLite Error", "SQLite3.dll Can't be Loaded!")
	Exit -1
EndIf

$FN="C:\Users\stefano\Desktop\New folder (4)\global-messages-db.sqlite"
$Handle=_SQLite_Open($FN=":File:"); This is what is shown in the examples, however, it does not work. (I replaced "Memory" with "File")
;MsgBox(0,"",$Handle)
_SQLite_Query(-1, "SELECT docid FROM messagesText_content ORDER BY 1;", $hQuery)
While _SQLite_FetchData($hQuery, $aRow) = $SQLITE_OK
$sMsg &= $aRow[0]
WEnd
MsgBox(0, "SQLite", "Get Data using a Query : " & $sMsg)
_SQLite_Shutdown()
