1. Create a calculated field with a select query
Build a Select query, add the "Fleet Transport" table, and drag all of its fields to the design grid. As shown in figure, as long as the "net weight: Gross weight-tare" is filled in the blank column, the system automatically adds "[]" to the "gross weight" and "tare" to indicate that they are fields. Save this query as "Fleet transport inquiries". The following table is the newly produced Fleet Transport query, the net weight is calculated automatically: Fleet Transport Inquiries Driver goods category gross weight tare weight net Lee generous other 75.00 25.00 50.00 Lee Generous other 135.00 45.00 90.00 Zhao Beautiful other 75.00 25.00 50.00 Cute Other 150.00 50.00 100.00 Zhao Beautiful fine powder 19.70 5.40 14.30 piece lovely fine powder 20.70 5.40 15.30 Lovely fine powder 20.60 5.40 15.20 Lovely ore 19.60 5.40 14.20 Lovely fine powder 20.60 5.40 15.20 Lovely fine powder 21.10 5.40 15.70 piece lovely ore 21.20 5.40 15.80 Li Dafang Fine powder 17.40 5.40 12.00 Zhao Beautiful waste stone 120.00 40.00 80.00 Zhao Beautiful other 15.00 5.00 10.00 Lee Generous waste stone 105.00 35.00 70.00 Zhang lovely waste stone 105.00 35.00 70.00 zhao Beautiful waste stone 105.00 35.00 70.00
