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.
I hope you can help me with this. I need to connect to a Database using Cloudera ODBC Driver for Impala. I installed the driver, created a User DSN (drona2) and tested it successfully (got the message: Successfully connected to data source!) but when I try to connect to the database using a Conneciton String, it simply didn't work.
I tried connecting to the database using the User DSN, I previously created, that has all parameters needed but got the following error:
$ProviderDatasource = 'DSN=drona2;'
$conn_Database = ObjCreate ("ADODB.Connection")
$conn_Database.ConnectionString = $ProviderDatasource
==> The requested action with this object has failed.:
Also I tried adding all parameters to my connection string as follows but also got the same error:
$ProviderDatasource = 'Driver=Cloudera ODBC Driver for Impala;Host=MyHost.domain.com;PORT=21050;AuthMech=3;UID=MyUserId@domain.com;PWD=MyPasswordc;Schema=default;SSL=1;AllowSelfSignedCerts=1;AllowHostNameCNMismatch=1;CheckCertRevocation=1;KrbFQDN=_HOTS;KrbServiceName=impala;ServicePrincipalCanonicalization=1'
I hope someone has used this driver successfully before and can shed some light here.
If you need additional information, let me know.
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
