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
..let's say I store in a mysql column "[1,2,11,12,123]".
How can I make s query to get all those rows that is 1, or is 12, etc ?
I'm using mysqlnd 5.0.11-dev - 20120503
Any advise on what technique I should use is welcomed
PS: ..I'm adding a comma to each end, as in [,1,2,11,12,123,] and will search with like %,12,% .
Not pretty but I'm in a hurry and can't come up with a better solution =/
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 thought I might share my little Language UDF plus the more powerful SciTE Tool to ship Strings from SciTE into the xml file. While I haven't had the time to fully adapt the small UDF to one of the big XML-UDFs the so called "Language Transmitter" that basically writes the XML file for you runs mostly on "XML DOM wrapper (COM)" by eltorro. The Transmitter should work with other XML-Language-UDFs depending on their encoding.
First let's start with the UDF, there are two functions of interest: _LangInit($sFilePath) and s($sString) As you will have guessed, _LangInit($sFilePath) is called once to initialize the UDF and s($sString) is used to receive the string to your key. Plain and simple.
Now to the actual "new" part, the Language Transmitter. It basically allows you to transfer a selected String from SciTE into a xml file. While doing so it will scan for AutoIt variables, macros etc. and parse the string to fit StringFormat(). It then saves the formatted string in the xml file and returns the formatted call into SciTE. If the selected string is already defined it will directly parse the key into SciTE. To change the default output file, you can either edit the ini-file in the @ScriptDir of the LanguageTransmitter.exe or press Alt+A on empty space again and keep clicking cancel/no until the Transmitter let's you select the current output file. Standard output is strings.xml in the current opened AutoIt Script.
; given the line: MsgBox(16, 'Error', 'Error message') ; select 'Error' run the Transmitter follow the instructions, repeat with 'Error message'. Outcome (e.g.): MsgBox(16, s('Error'), s('Error_msg')) ; Variables and Macro example: $sString = "Value: " & $iValue & @CRLF & 'Another value: '& $iValue2 ; Select the full string including all AutoIt variables and macros etc. in SciTE and press Alt+A (default) to run the LanguageTransmitter ; follow the instructions and it will then paste a formatted string like that into SciTE: $sVar = StringFormat(s('Key'), $iValue, $iValue2) ; the correlating xml entry should look like that: ; <string name="Key">Value: %s\r\nAnother value: %s</string> ; as you can see @CRLF has been replaced with \r\n as well. If you are working on a project and want to directly add a string to the xml file just start the Language Transmitter without selecting any text, enter your string and a key.
Since xml files are required all examples can be found in the zip file. There are two examples, one includes a language selection interface.
Language File Checker
I added a script to check whether the xml file contains all required strings or even unnecessary strings.
Hope you like my little helper!

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.
