I have created this function for a database, but I can not make it work. I always have two error messages: "not an error" ... and the file created, in the script directory, does not contain anything.
Global $sDBName = "Hen.db" Func DatabaseTable() Local $sConnDB _SQLite_Startup() If @error Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", "SQLite.dll Can't be Loaded!") Exit -1 EndIf $sConnDB = _SQLite_Open($sDBName) If @error Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", "Can't Load Database!") Exit -1 EndIf If Not _SQLite_Exec($sDBName, 'CREATE TABLE Animal ("Name", "Age");') = $SQLITE_OK Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", _SQLite_ErrMsg()) If Not _SQLite_Exec($sDBName, 'INSERT INTO Animale VALUES ("Charlie","5");') = $SQLITE_OK Then MsgBox($MB_SYSTEMMODAL, "SQLite Error", _SQLite_ErrMsg()) _SQLite_Close($sConnDB) _SQLite_Shutdown() EndFunc
I've been searching on how to select the first row in my database which includes a time column based on the latest start_time date for today's date.
This is my current code:
Local $iCurrentDate = _Now() Local $sqlHandle = _dbOpen($sDbPath) Local $aResult, $iRows, $iCols _SQLite_GetTable2d($sqlHandle, "SELECT start_time FROM " & $srawDb & " ORDER BY datetime(start_time) DESC LIMIT 1", $aResult, $iRows, $iCols) _ArrayDisplay($aResult) _dbClose($sDbpath) What it does is it gets the first row entry in the database however it does not select the latest start_time entry in the database, it always select the first row. I've tried changing DESC to ASC to see if that will do it but the issue still remains. Any thoughts on this? Thanks in advance.
The date format in the database is by MM/DD/YYYY HH:MM:SS.
In my recent project I'm downloading a bunch of data, so I decided to store it in a SQLite database. NOTE: I'm using sqlite3_x64.dll
Everything is working just fine but I'm struggling with getting the Median value. SQLite has an Average function but not a Median one.
I googled but all of the provided solutions are way above my pay-grade. After some more searching I found 'extension-functions.c' on the SQLite site where Median is included. After almost an hour of struggling I was able to successfully compile it into a DLL.
So I downloaded @jchd's SQLiteExtLoad.au3 as seen here:
But I'm getting these errors:
"Path\SQLiteExtLoad.au3"(21,40) : warning: $g_hDll_SQLite: possibly used before declaration. Local $RetVal = DllCall($g_hDll_SQLite, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^ "Path\SQLiteExtLoad.au3"(21,40) : error: $g_hDll_SQLite: undeclared global variable. Local $RetVal = DllCall($g_hDll_SQLite, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^ So I tried, copying the function to my file and changing the DLL variable ($g_hDll_SQLite) directly to the DLL location (C:\...\.. .dll), but now this error fires
If __SQLite_hChk($hConn, 1) Then Return SetError(@error, 0, $SQLITE_MISUSE) To be honest, I don't know what to use as the $hConn - handle of connection.
I would appreciate any help, be it getting the median using SQLite queries or getting the DLL extension loaded using AutoIt.
EDIT: well, I suspect the $hConn variable refers to the return value of the _SQLite_Open function. Well, at least now _SQLite_EnableExtensions doesn't give errors. Now I run into problems with _SQLite_LoadExtension, which gives error -1, and extended 1. Apparently the 1 constant is a generic error where other error do not apply.
BTW, anybody knows whether I need to compile the extension DLL "into" x64 when I use a x64 SQLite? That might be the problem...
EDIT2: I recompiled the dll and tried it using the SQLite3.exe and it works, so I'm confident the extension DLL has been created correctly
I have been testing AutoIt 220.127.116.11 with SQLite, and the Help File examples. The examples that I have tested are throwing errors or not doing anything. I have sqlite3.dll, sqlite3_x64.dll, and sqlite3.exe in the directories with the testing script. I am copying the examples directly from the help file into a test script for testing with no edits. The _SQLite_GetTable2d example is returning an error ("Library used incorrectly") with each _SQLite_Exec command. The _SQLite_FastEncode example returns an empty dialog box. The _SQLite_Exec example only prints out the SQLite version, and nothing else in the SciTE console. Currently, I'm still searching for what is causing this issue. I'm on Windows 7 Enterprise 64-bit. Is anyone else having this issue?
I have SQLite setup within my AutoIT program...I'm trying to accomplish what should be a relatively simple task. I want to be able to return an array of 'table' names for an established database...I believe this might be possible using the '_SQLite_SQLiteExe' command...since it seems to be able to access SQLite schemas...? The ".tables" command is one of them...if I am not mistaken that command returns a list of all table names in the active database.
I am attempting the following:
#include <SQLite.au3> #include <SQLite.dll.au3> Global $hDb, $sIn, $sOut ... $sIn = ".tables" & @CRLF _SQLite_SQLiteExe($hDb, $sIn, $sOut) if @error == 0 Then ;Show Table (using SQLite3.dll) Else if @error == 2 Then ConsoleWrite("ERROR: Sqlite3.exe file not found" & @CRLF) Else ConsoleWrite("ERROR: @error=" & @error & " when calling _SQLite_SQLiteExe" & @CRLF) EndIf ;@error is "2"...OR NOT... EndIf ;@error is "0"...OR NOT... ... The error being thrown is "ERROR: Sqlite3.exe file not found" ...
Am I required to have the Sqlite3.exe installed in my directory (i.e. @ScriptsDir)...??? I do not have it in there at present because I did not believe it was necessary with the 'include' calls to "SQLite.au3" and "SQLite.dll.au3"...any advice appreciated. Thanks in advance.
