Pulling report from SQL

[Godders199]

Hello, i have the following code which runs ( slowly) to pull two reports from an SQL internet database, just seems to run slowly, have had timer on the last few days and it takes between 294 seconds and 684 seconds to complete. my problem is that when i use debug step through it only takes 148 seconds.

Is there a reason why it takes so much longer when left to run from start to finish.

Dim t
t = Timer
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.Calculation = xlCalculationManual

Sheets("checksmart").Visible = xlSheetVisible
Sheets("checks").Visible = xlSheetVisible
Sheets("Info").Select
Calculate

Qlink = Sheets("Info").Range("A56").Value

Sheets("checkSmart").Select

Range("A1:AZ50000").Select
Selection.ClearContents
Range("L:L").NumberFormat = "dd/mm/yyyy mm.hh"
Range("u:u").NumberFormat = "dd/mm/yyyy mm.hh"
ActiveWorkbook.XmlImport URL:=Qlink, ImportMap:=Nothing, Overwrite:=True, Destination:=Range("$A$1")

Sheets("Info").Select


Qlink = Sheets("Info").Range("A69").Value

Sheets("checks").Select

Range("A1:AZ50000").Select
Selection.ClearContents

ActiveWorkbook.XmlImport URL:=Qlink, ImportMap:=Nothing, Overwrite:=True, Destination:=Range("$A$1")

Application.ScreenUpdating = True
Application.DisplayAlerts = True
Application.Calculation = xlCalculationAutomatic
Sheets("checksmart").Visible = xlSheetHidden
Sheets("checks").Visible = xlSheethiddden

Sheets("instructions").Select
MsgBox Round(Timer - t, 2) & "sec."
End Sub

Are you clearing all existing data before loading up new data, personally I would delete the current sheet and create a new one with same name rather than selecting a huge range unless of course you have formulas on the worksheet

Thanks, apart from formatting no formulas, will google to find out how to code in new sheet
