- p 113. “STRICT DATA TYPE: TIME OF DAY” tells FM that:
only time values that represent REAL CLOCK TIMES are acceptable. You CANNOT enter a duration such a “36:45:23”
- When would you use “STRICT DATA TYPE: UNIQUE”?
Use it on ID NUMBERS, USER NAMES, or other info that SHOULD IDENTIFY A SINGLE PERSON UNIQUELY.
- When would you use “STRICT DATA TYPE:EXISTING VALUE”?
When the field should contain only values that are already on that field in other records, such as 1957 Ford car models (so that you don’t enter Cadillac DeVille).
- “STRICT DATA TYPE: IN RANGE” lets you specify:
a MINIMUM and a MAXIMUM allowable value
- “IN RANGE” does NOT work for what type of fields?
it works on ALL the STANDARD data types, since they all have a concept of order.
- What does “IN RANGE: ADAM TO JOHNSON” do?
It DOES NOT VALIDATE Schulz or Torres, but accepts Harrison.
- “IN RANGE.” Range validation is most common in:
Number, Date, and Time values. You can require the age to be between 0 and 100, or the birth date to be between 1-1-1900 and 1-1-2007.
- “MAXIMUM NUMBER OF CHARACTERS” prevents you from entering 10 characters when you’ve specified 8 to be the max. How do you specify a MINIMUM number of characters?
You must use a CALCULATION: Length (MyField)>=5,
but you MUST USE the “VALIDATE BY CALCULATION” for this option.
“MY FIELD” is replaced by the name of the field, such as the field named ZIP CODE.
