Undeclared global variable

[Ray67]

Hello,

I'm very new to autoit. Still trying to learn it.  I'm get undeclared global variable in the following script

;Declare error handler
Local $oErrorHandler = ObjEvent("AutoIt.Error", "_ErrFunc")

;Declaration variables for SQL Connection
Local $ServerAddress = ""
Local $ServerUserName = ""
Local $ServerPassword = ""
Local $DatabaseName = ""

$constrim="DRIVER={SQL Server};SERVER="&$ServerAddress&";DATABASE="&$DatabaseName&";uid="&$ServerUserName&";pwd="&$ServerPassword&";"
$adCN = ObjCreate ("ADODB.Connection") ;<==Create SQL connection

;MsgBox(0,"",$constrim )
if @error Then
  MsgBox(0, "ERROR", "Failed to connect to the database")
  Exit
Else
  MsgBox(0, "Success!", "Connection to database successful!")
EndIf

$sQuery= "Select * from EftProv, Amt WHERE LName = 'A'"

$result= $dbCon.Execute($sQuery) (undeclared global variable error)
MsgBox(0,"MD Found:",$result.Fields( "ID" ).Value )
$adCN.Close ;==>Close the database

Thank you

It's most likely related to $dbCon, I don't see it initialized anywhere in the snippet you posted

$dbCon isn't declared anywhere in your script.

Thanks for your help.

I think I fixed variable issues. 

Now I have another issues. It's connecting to the sql sever but it's not returning any value.

;Declare error handler
Local $oErrorHandler = ObjEvent("AutoIt.Error", "_ErrFunc")

;Declaration variables for SQL Connection
Local $ServerAddress = ""
Local $ServerUserName = ""
Local $ServerPassword = ""
Local $DatabaseName = ""

$constrim="DRIVER={SQL Server};SERVER="&$ServerAddress&";DATABASE="&$DatabaseName&";uid="&$ServerUserName&";pwd="&$ServerPassword&";"
$adCN = ObjCreate ("ADODB.Connection") ;<==Create SQL connection

 

 

;MsgBox(0,"",$constrim )
if @error Then
  MsgBox(0, "ERROR", "Failed to connect to the database")
  Exit
Else
  MsgBox(0, "Success!", "Connection to database successful!")
EndIf

$sQuery= "Select * from EftPr, Amt WHERE LName = 'AD'"

$result= $adCN.Execute($sQuery)
MsgBox(0,"MD Found:",$result.Fields( "LName" ).Value )
$adCN.Close ;==>Close the database
