Note
The primary key serves only one purpose: to uniquely identify the record. Any name
can be used for this field. We have used FuelID for convenience, so we know to
which table it belongs.
3) All other fields (Date, FuelCost, FuelQuantity, Odometer, and PaymentType):
• Type the next field name in the Field Name column.
• Select the Field Type for each field.
– For Date use Date[DATE]. (Press the D key to select it.)
– PaymentType uses Text [VARCHAR], the default setting.
– All other fields use Number [NUMERIC]. (Press the N key once to select it.)
• FuelCost, FuelQuantity, and Odometer need changes in the Field Properties section
(Figure 179).
– FuelQuantity: Change Length to 6 and Decimal places to 3. (Many fuel pumps
measure fuel to thousands of a gallon in the USA where I live.)
– Odometer: Change the Length to 10 and the Decimal places to 1.
– FuelCost: Change the Length to 5 and Decimal places to 2. Click the Format
example button (Figure 179). This opens the Field Format window (Figure 180).
Use Currency as the Category and your currency as the Format. My currency
has two decimal places. Use what is appropriate for yours.
