Need a macro to delete all the data in tbl_output based on the field "level" - so delete everyone who is not a level 1.

the fields in the table are:-
Id

Try this in a query:

DELETE *
FROM YourTable
WHERE Level <> 1

Open in new window


and if you need a macro to run it, use the RunQuery action.

<<  use the RunQuery action. >>

Sorry - the action is actually "OpenQuery".  (just use the default options with that action)

That is not a macro as you'd asked for... it is VBA code :-)

To fill in the blanks in the code:


sub tidyup()

dim strSQL as string
strSQL = "DELETE * FROM tbl_output WHERE Level <> 1"

Docmd.setwarnings false
Docmd.RunSQL strSQL   
Docmd.setwarnings true
end sub

Open in new window



Or my preferred method:

sub tidyup()

dim strSQL as string
strSQL = "DELETE * FROM tbl_output WHERE Level <> 1"
currentdb.execute strSQL, dbFailOnError

end sub

Open in new window

Just as an aside.., comparing macros and vba... while a lot is possible with macros, including this particular task, VBA in the long run is the way to go.

VBA is easier to maintain and develop, gives you (the developer) more control, and provides you with meaningful error messages when things go wrong.
