This is an example how to access/query different kind of Databases with AutoIt. The demo contains also test Databases, so the script functions for most of the provided database connections. Databases covered here: Oracle (no demo database for this one) MS SQL Server (no demo database for this one) SQLite (requires installation of the SQLite ODBC driver software available here: http://www.ch-werner.de/sqliteodbc/ ) Of course SQLite is natively available in AutoIt but in some cases it might be preferable to use the ODBC approach accessing the database via the same scripted method, for example if you use different Databases in the same script, it is much easier to code. Excel DBase DBF MS Access CSV Text driver (semicolon delimited and comma delimited) The example script is based on Kinshima’s Oracle SQL example . I like the Dim by pack method, much better than redim one row at the time, which too slow. All the databases have the same data content (‘Timeline_of_space_exploration’) to keep the examples similar for every database. The result of each SQL will be displayed in Arraydisplay, togheter with a window containing the ADO-less connection string (yellow) and SQL. #Region ;**** Directives created by AutoIt3Wrapper_GUI **** #AutoIt3Wrapper_Res_Comment=Comprehensive DSN-Less Database connection demo #AutoIt3Wrapper_Res_Description=DSN-Less Database connection demo #AutoIt3Wrapper_Res_Fileversion=1.0.0.0 #AutoIt3Wrapper_Res_LegalCopyright=GreenCan #EndRegion ;**** Directives created by AutoIt3Wrapper_GUI **** #include <array.au3> #include <MsgBoxConstants.au3> #include <WindowsConstants.au3> #include <EditConstants.au3> #include <GUIConstantsEx.au3> #include <ButtonConstants.au3> Opt('MustDeclareVars', 1) Global $oODBC_Connection = ObjCreate("ADODB.Connection") Global $oODBC_RecordSet = ObjCreate("ADODB.Recordset") Global $bODBC_conn = False Global $oErrADODB = ObjEvent("AutoIt.Error", "_ErrADODB") Global $bConn_error = False Global $sConnectionString, $sSQL Global Const $iDark_Blue = 0x2601D3 Global Const $iLight_Green = 0xEAFFE8 Global Const $iYellow = 0xFFFF99 ; setup GUI to display SQL Global $hGUI_View_SQL = GUICreate("SQL", 500, 500, 10, 10, $WS_CAPTION);, $WS_EX_TOPMOST) Global $hConnString = GUICtrlCreateEdit("", 5, 3, 490, 38, BitOR($ES_AUTOHSCROLL, $ES_READONLY, $ES_WANTRETURN, $WS_HSCROLL)) GUICtrlSetColor(-1, $iDark_Blue) GUICtrlSetBkColor(-1, $iYellow) Global $ViewSQL = GUICtrlCreateEdit("", 5, 45, 490, 450, BitOR($ES_AUTOVSCROLL, $ES_AUTOHSCROLL, $ES_READONLY, $ES_WANTRETURN, $WS_HSCROLL, $WS_VSCROLL)) GUICtrlSetColor(-1, $iDark_Blue) GUICtrlSetBkColor(-1, $iLight_Green) GUISetState() #========== Demo ============= Global $sDatabaseLocation = @ScriptDir & "\TestDatabases" #========== Oracle ============= ;~ #cs ;~ Not demo-able except if you have an Oracle instance ;~ #ce $sConnectionString = 'DRIVER={Oracle in OraClient11g_home1};DBQ=myDatabase.world;uid=myUserID;pwd=myPassword;' $sSQL = 'SELECT sysdate AS "Sysdate Raw", to_char(sysdate, ''Dy DD/MM/YY HH24:MI'') AS "Now" FROM dual' Format_SQL($sSQL, $sConnectionString) MsgBox(0,"Oracle SQL","You require to have access to an Oracle instance and modify the connection string before proceeding without error." & @CRLF & "The current Connection string will generate a COM error.")
