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 188.8.131.52 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.
I am working on a Video Player Test Script. I am reading a text file into a 3d array to be displayed in a GUI.
[x]UsageCount -> Up to a 4 digit number
In the GUI the user can check the filename box, edit the number of usages and check EnableUsageCount to turn on the UsageCount control using the UsageCount number for the maximum number of plays.
To make this easier to deal with I have removed the EnableUsageCount section, and am just concentrating on getting a method to put the edited (or unchanged) UsageCount in the array. Currently nothing is read into the array, due to my using the wrong method in the Case statement.
Here are code snippets of what I am trying to do:
; Snippets from script ; I read the text file at the bottom and put the .mp4 filenames in $aManifest[x] and UsageCount in $aManifest[x] ; Then I create a GUI to display the .mp4 filenames with checkboxes and the UsageCount to the right. UsageCount is editable by the user. ; If the filename is checked, I want to read the filename into $aCheckedVideos[x] and the updated UsageCount in $aCheckedVideos[x] ; The GUICtrlRead($aVideoName[$i]) with Case $GUI_CHECKED & UNCHECKED works for the checkboxes ; This section puts the filenames in the GUI with a checkbox For $i = 0 to $iMMCount Step 1 $sMP4Text = $aManifest[$i] $iMP4Length = StringLen($sMP4Text) $aVideoName[$i] = GUICtrlCreateCheckbox($sMP4Text,$iLeft, $iTop) $iTop += 30 Next ; This section reads numbers from the Manifest array, and I want to be able to change the number and have them saved. ; So the Case $GUI_CHECKED & UNCHECKED won't work here, and I can't figure out what I should be doing here. For $i = 0 to $iMMCount Step 1 $sUsageText = $aManifest[$i] $aUsageCount[$i] = GUICtrlCreateInput($sUsageText,$iLeft, $iTop, 50,18, $GUI_DOCKAUTO) GUICtrlSetPos($aUsageCount[$i],200) $iTop += 30 Next While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $idCloseGUI For $i = 0 To $iMMNewCount Step 1 Switch GUICtrlRead($aVideoName[$i]) Case $GUI_CHECKED $aCheckedVideos[$i] = $aManifest[$i] ; If checked, I put the results into a two D array Case $GUI_UNCHECKED ; where Video Name is $aCheckedVideos[x] EndSwitch Switch GUICtrlRead($aUsageCounter[$i]) Case $GUI_CHECKED $aCheckedVideos[$i] = $aUsageCount[$i] ;I want to put the text (numbers) in $aCheckedVideos[x] Case $GUI_UNCHECKED ;but what is returned is blank, probably due to EndSwitch ; $GUI_CHECKED being the wrong thing. Next ExitLoop EndSwitch WEnd ;The txt file I'm reading has the following: ;~ /** Title #1: Big Buck Bunny 1080p **/ ;~ "Name": "Big Buck Bunny", ;~ "URI": "..\\MediaFiles\\bbb_1080_60s.mp4", ;~ "UsageCount": 9999, ;~ "URI": "..\\MediaFiles\\bbb_1080_60s_enc1.mp4", ;~ "UsageCount": 45, ;~ "URI": "..\\MediaFiles\\bbb_1080_60s_enc1.mp4", ;~ "UsageCount": 2, ;~ /** Title #2: Tears of Steel 4K **/ ;~ "Name": "Tears of Steel 4K", ;~ "URI": "..\\MediaFiles\\tos_4K_60s_HEVC.mp4", ;~ "UsageCount": 9876, ;~ "URI": "..\\MediaFiles\\tos_4K_60s_HEVC_enc2.mp4", ;~ "UsageCount": 0, ;~ "URI": "..\\MediaFiles\\tos_4K_60s_HEVC_enc2.mp4", ;~ "UsageCount": 5, I am certain that the section
$aCheckedVideos[$i] = $aUsageCount[$i] ;I want to put the text (numbers) in $aCheckedVideos[x]
Case $GUI_UNCHECKED ;but what is returned is blank, probably due to
EndSwitch ; $GUI_CHECKED being the wrong thing.
is wrong, and this is what I am looking for help with. Instead of $GUI_CHECKED what should I be looking for?
The worst part of this is I had this working late last night, and then lost my changes and cannot for the life of me remember how I had this working.
Help is truly appreciated!
Good evening guys
I am working on a little project, in which I have to retrieve 8000+ rows of data from a table, from a SQLite database, to populate a combobox
This is what I tried 'til now, but it still takes about 12 seconds to populate the combobox.
_SQLite_Exec($objDatabase, "BEGIN TRANSACTION;") If _SQLite_GetTable($objDatabase, "SELECT DISTINCT Comune FROM LISTA_COMUNI;", $arrRisultatoQuery, $intRighe, $intColonne) = $SQLITE_OK Then For $i = 2 To UBound($arrRisultatoQuery) - 1 If $i < UBound($arrRisultatoQuery) - 1 Then GUICtrlSetData($cbo_ComuneNascita, $arrRisultatoQuery[$i] & "|") Else GUICtrlSetData($cbo_ComuneNascita, $arrRisultatoQuery[$i]) EndIf Next _SQLite_Exec($objDatabase, "COMMIT;") Are there any other solution to retrieve 8000+ records from a SQLite database?
Thank you very much
