MSSQL database backup via autoit

Recommended Posts

Hello guys,

I've created script which is making backup database in MSSQL2012 and using    "_SQL.au3"

But I have a problem with script, it's working well with other database well (1Gb, 35Gb), but with "Test1Database" (250Gb) it doesn't work and giving me error:

""C:\Program Files (x86)\AutoIt3\Include\_SQL.au3" (402) : ==> The requested action with this object has failed.:
$hQuery = $hConHandle.Execute($vQuery)
$hQuery = $hConHandle^ ERROR "

With others databases I've tested my script it's works well but size  significantly smaller (size)  compare to "Test1Database".  The space on disk more than enough.

Can you give a little help with that issue.

My script is bellow:


#include "_SQL.au3"
#include "Forms\MainForm.isf"

Dim $ObjSQL, $server, $db, $username, $password
$server = "Server name"
$db = "master"
$username = "user"
$password = "pass"
$sqlcod1 = "EXEC [dbo].[ReleaseBackup]"

GUISetState(@SW_SHOW, $Mainform)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE

        Case $idEODButton

            Func _Button_Click()

               $MsgSQL = _SQL_GetErrMsg()

                ; Connect to server ;
                $ObjSQL = _SQL_Startup()

                If $ObjSQL = $SQL_ERROR then Msgbox(0 + 16 + 262144, "Error", _SQL_GetErrMsg())
                If _sql_Connect(-1, $server, $db, $username, $password) = $SQL_ERROR then
                    Msgbox(0 + 16 + 262144, "Error", _SQL_GetErrMsg())

                ; Run backup ;
                $Query1 = ($sqlcod1)
                If _SQL_Execute($ObjSQL,$Query1) =  $SQL_ERROR then
                    Msgbox(0 + 16 + 262144, "Error", _SQL_GetErrMsg())

                If $MsgSQL = "" Then
                  $MsgSQL = _SQL_GetErrMsg()


            EndFunc   ;==>_Button_Click

HI @Aibek and welcome.

I am just curious... 

$sqlcod1 = "EXEC [dbo].[ReleaseBackup]"

Maybe ReleaseBackup is a "stored procedure" not existant in your "big database" ?


Btw and maybe off topic.. usually for backup (and restore) I use a single line like that:

RunWait(@ComSpec & " /c sqlcmd -U user -P password -S yourDBServer -Q  ""backup database " & $DBname & " to disk = '" & $path2db & "backup\" & $DBname & ".dat' "" -o " & $path2db & "backup\log_backup.txt")

Maybe you can try this way.

Sure you can use variables also for user/psw/server.

You will need the SQLCMD utility, if you run the script on the DB server often you already have it in path, otherwise check here
