  OK.

  So... fix the values *before* you put them into SQL.

  That is completely backwards.  Don't fix the columns.  Fix the
accounting packet in the "preacct" section:


	if (Mikrotik-Host-IP) {
		update request {
			Tmp-Integer-0 := "%{Acct-Input-Octets}
			Tmp-Integer-1 := "%{Acct-Output-Octets}

		}

		update request {
			Acct-Input-Octets = "%{Tmp-Integer-0}"
			Acct-Output-Octets = "%{Tmp-Integer-01}"
		}
	}

  It doesn't.  See "man unlang".  The documentation says where you can
put conditions.
