This is my alert about this practice can (or not) be considered recommended. In any approach, when the enumeration is recompiled, its equivalent check constraint must be recompiled, too. In this last example, a check constraint becomes more complex, but I think that is sufficient uses a between 0 (minimal value) and maximum values. That is not in this rule, targets any combination of another values. ![]() ![]() In this implementation, enumeration values that specify option must be an power of 2 number. If you browse the enum definition, you'll find that YesNoCancel is equal to sum the values of Yes, No and Cancel. Or they can beĬombinated to use two or three of them. If you wish to use a default value, you should enter it without quotes in. Here, any option can be used to display just one button. How do I create an enum field in a table To create an enum field follow the same procedure as you would for any other field, choose enum in the Type column of the Table Structure form, and then in the Length column enter the enum values as comma separated quoted strings. The enumeration uses Yes, No or Cancel (and other values). The enum generation code is like this: // Get the current application domain for the current thread AppDomain currentDomain AppDomain.CurrentDomain // Create a dynamic assembly in the current application domain, // and allow it to be executed and saved to disk. ![]() Here, an database check constraint with only allowed values handles the restriction to use only the enumeration values.īut in some scenarios, more than one option can be used, such as the buttons shown in . Advantages of Sequel Pro: Here are some of Sequel Pro's best features: 1) Unlimited Database Connections: Sequel Pro lets you create an unlimited number of database connections in a favorites list, so you can streamline your workflow, and access frequently-used databases. In this scenario, enum values can be just an incremented value. Lets use MartialStatus, by example - a person can only fits in one option between 'married', 'widowed' or 'single'. Simple enums uses only one option in its value definition.
