Allowed values

Previous Next

When defining a domain, you can restrict the values allowed in the columns based on the domain:

You can set predefined domain attributes. For example, if you want a number domain to have only values between 1 and 100 you can set Min. Value = 1 and Max. Value = 100.

You can enumerate one-by-one which values are allowed. For example, you can enumerate the values 'Single', 'Married' and 'Divorced' as allowed values for columns holding a person's marital status.

For a domain, you can specify a regular expression pattern. Only values that match that pattern are allowed in columns based on that domain.

You can write USoft-style SQL to define business rules for domain values. You do this by creating domain constraints.

There is a link between allowed values and display types:

For checkboxes, allowed values will be limited to 'Y' and 'N', or to 'Yes' and 'No'. If the column has Mandatory = No, the empty value or NULL value is a third possibility.

If you have enumerated a very limited number of allowed values, it is appropriate to use the Option Buttons display type.

If you have enumerated a larger set of allowed values, use a dropdown list.

If you have a Slider a the display type of a number column,l it is appropriate to set the Min. Value and Max. Value predefined domain attributes.
