Limit the maximum value in a number field
When setting up the properties of a field, what is the expression for limiting the numbers which can be entered to <=9?
The number entered in this field must be 9 or less but not null.

This is not possible with MySQL as it does not support check constraints.

The only workaround is to use a trigger.
