Solution to some ADODB.Connection problems for SQL Server

4 posts in this topic

#1 ·  Posted (edited)

I had a problem getting a connection to "SQL Server" on 64 bit PCs (running XP) even though 32 bit PCs connected easily.

Even compiling for 32bit was (initially) insufficient and to get it working at all on a 64bit PC, I ended up forcing its use of TCP/IP protocol by specifying a port number (that is apparently picked up as a default by 32 bit PCs once "SQL Server" has been added with it configured in "Control Panel --> Administrative Tools --> Databases(ODBC) --> Add --> SQL Server --> Client Configuration"

This worked for me on a 64bit PC, but only when compiled in 32bit:

$sqlCon = ObjCreate("ADODB.Connection")

$sqlCon.Open("DRIVER={SQL Server};SERVER=name.of.server,port_number;DATABASE=name_of_database;UID=logon_ID;PWD=password;")

If @error Then
 MsgBox(0, "Problem", "SQL Connection Failed")
 MsgBox(0, "Success", "SQL Connection OK")

Also, I found that the "SQL Server" needed to be added to the Databases(ODBC) as shown above (and tested OK) before the AutoIT script worked but (strangely) it could be later removed from Databases(ODBC) and it still worked (perhaps it just needed to setup defaults).

Does anyone know how I can get the above working when compiled in 64bit too?

On a X64 bit PC, the above script it will fail to work with:


but works OK with

Which version of the SQL driver do you have installed?

Have you tested this COM ODBC connection with VBscript or some other x64 software to establish it is really AutoIt3 giving the problem?

I have closed you bug report for now as I am not convinced this is an AutoIt3 issue.

It is a function of the bitness of the SQL Server ODBC component/driver that is installed. It looks like the 32-bit version of the SQL Server ODBC component/driver installed, and so, you must compile your script for a 32-bit executable. If the 64-bit version of the SQL Server ODBC component/driver was installed, then you would have to compile your script to a 64-bit executable - otherwise you would receive similar errors and it would not work if compiling to a 32-bit executable.

I think the link below, although it does not apply to straight SQL, it has a lot to explain.

      Dear all,
      I already have a formula which will select doublicates, but sometimes there might be entries with additional information starting after "-", which I now want to trim away.
      Current formula is:
      Select DISTINCT a.title, a.oid, a.size, a.disk from DB a, DB b where (a.title like b.title and a.oid <> b.oid)" & $ActiveDisks_Filter & " AND (a.comment <> 'Delete' AND b.comment <> 'Delete') Order by a.title ASC, a.size DESC; testwise I want to add a simple solution like left, but afterwards I get an error but I do not know why.
      Select DISTINCT a.title, a.oid, a.size, a.disk from DB a, DB b where (left(a.title,15) like b.title and a.oid <> b.oid) Order by a.title ASC, a.size DESC; Error: near "(": syntax error: Finally I would like to insert intstr to search for "-" but currently I am not able to extend my current code =/
      Thanks a lot for your help.
      EDIT: hey, I managed it, left was not working also it was somehow shown that the tool knowed the comment. I did it now with substr+instr
      (substr(a.title, 1, instr(a.title, ' - '))

      I have code that does a WMI SQL query to find all defined printers, and I want to parse the returned object in several places.  However, after parsing it the first time, all other times fail to find any printer objects.
      Here is my test code:
      test() Func test() Local $oPrinters, $oPrinter, $err, $cnt, $oP, $query $query = "SELECT * FROM Win32_Printer" $oPrinters = doQuery($query) $err = @error LogMsg("+++: $err = " & $err & ", isObj($oPrinters) = " & IsObj($oPrinters)) If ($err == 0) Then LogMsg("FIRST LOOP") ; <=== FIRST LOOP $cnt = 0 $oP = $oPrinters LogMsg("+++: isObj($oP) = " & IsObj($oP)) For $oPrinter In $oP $cnt += 1 LogMsg("+++: isObj($oPrinter): " & IsObj($oPrinter) & ", $oPrinter.Name ==>" & $oPrinter.Name & "<==") Next LogMsg("+++: Found " & $cnt & " printers") LogMsg("SECOND LOOP") ; <== SECOND LOOP $cnt = 0 $oP = $oPrinters LogMsg("+++: isObj($oP) = " & IsObj($oP)) For $oPrinter In $oP $cnt += 1 LogMsg("+++: isObj($oPrinter): " & IsObj($oPrinter) & ", $oPrinter.Name ==>" & $oPrinter.Name & "<==") Next LogMsg("+++: Found " & $cnt & " printers") EndIf EndFunc ;==>test Func doQuery($sQuery, $lnum = @ScriptLineNumber) #forceref $lnum LogMsg("+++:" & $lnum & ": doQuery(" & '"' & $sQuery & '"' & ") entered") Local $oWMIService, $oResults, $errstr Local $wbemFlags = BitOR(0x20, 0x10) ; $wbemFlagReturnImmediately and wbemFlagForwardOnly $oWMIService = ObjGet("winmgmts:\\" & "localhost" & "\root\CIMV2") If (IsObj($oWMIService)) Then $oResults = $oWMIService.ExecQuery($sQuery, "WQL", $wbemFlags) If (IsObj($oResults)) Then LogMsg("+++: doQuery() returns @error = 0, Good: returning the object") Return (SetError(0, 0, $oResults)) ;;; Good: return the object Else $errstr = "" _ & "WMI Query failed." & @CRLF _ & "This is the query:" & @CRLF _ & " " & $sQuery LogMsg("+++: ====>" & $errstr & "<===") LogMsg("+++: doQuery() returns @error = 1") Return (SetError(1, 0, $errstr)) ; Error: Query faled EndIf Else $errstr = "" _ & "WMI Output" & @CRLF _ & "No WMI Objects Found for class: " & @CRLF _ & "Win32_PrinterDriver" & @CRLF _ & "using this query:" & @CRLF _ & " " & $sQuery LogMsg("+++: ====>" & $errstr & "<===") MsgBox(0, "ERROR", $errstr) ; Error: Cannot get $oWMIService object Exit (1) EndIf EndFunc ;==>doQuery Func LogMsg($msg, $lnum = @ScriptLineNumber) ConsoleWrite("+++:" & $lnum & ": " & $msg & @CRLF) EndFunc ;==>LogMsg Parsing the returned $oPrinters object shows 5 printers:

      Hello guys !
      I'm stuck in something stupid (I guess), but since I've no clue on how to solve it, here I come
      I'm trying to collect the result of the query "select @@hostname" on MSSQL Server, but it doesn't work ... and I'm sure I'm connected to the database (I've successfully seen the database treeview).

      Looking for working code to  get full path of process  - both 32 & 64 bit.
      I tryed this bellow, but it works only for 32-bit processes, even if compiled for x64...

      I have an Autoit-based client GUI that uses a single MS SQL Server database. I have no problem connecting to and executing queries against this database from my AutoIT code, with the below exception:
      One of the database's stored procedures I need to execute requires a parameter that is a table. I've set up the appropriate table_type on the database and everything works fine on the database itself when I execute the stored proc with a table variable for the parameter (no AutoIT involved). The problem is that I can't figure out how to pass a table parameter from AutoIT, assuming it's even possible. The code below shows the two methods I've tried, both methods return a RecordSet object that is at EOF.
      #include <Array.au3> Opt("MustDeclareVars", 0) $sDBSrv = "" $sDBName = "INVDEV" $sADOName = "ADODB.Connection" $oSQLConn = ObjCreate($sADOName) $sConnStr = "Driver={SQL Server};Server=" & $sDBSrv & ";Database=" & $sDBName & ";Trusted_Connection=yes;" $oSQLConn.Open ($sConnStr) $rsoFacFriendly = $oSQLConn.Execute("SELECT TOP 5 FriendlyName FROM Facility") If Not $rsoFacFriendly.EOF Then $aFacFriendly = $rsoFacFriendly.GetRows() _ArrayDisplay($aFacFriendly) $rsoSPResults = $oSQLConn.Execute("EXEC spTableParameterPassTest " & $aFacFriendly) Select Case $rsoSPResults.EOF = False MsgBox(0, "sp exec1", "not end of file") $aSPResults = $rsoSPResults.GetRows() _ArrayDisplay($aSPResults) Case IsObj($rsoSPResults) = 0 MsgBox(0, "sp exec1", "rso isn't even an object") Case $rsoSPResults.EOF = True MsgBox(0, "sp exec1", "At end of file") Case Else MsgBox(0, "sp exec1", "Something else happened") EndSelect $rsoSPResults = 0 $rsoSPResults = $oSQLConn.Execute("EXEC spTableParameterPassTest " & $rsoFacFriendly) Select Case $rsoSPResults.EOF = False MsgBox(0, "sp exec2", "not end of file") $aSPResults = $rsoSPResults.GetRows() _ArrayDisplay($aSPResults) Case IsObj($rsoSPResults) = 0 MsgBox(0, "sp exec2", "rso isn't even an object") Case $rsoSPResults.EOF = True MsgBox(0, "sp exec2", "At end of file") Case Else MsgBox(0, "sp exec2", "Something else happened") EndSelect $rsoSPResults = 0 $rsoFacFriendly = 0 $oSQLConn.Close $oSQLConn = 0 Exit
