Course Introduction:The ENUM data type differs from the standard data type in that it is an enumerated list of strings from 1 to 65,535 that represents the allowed values of the field. When you define an ENUM, you are creating a list of items from which a value must be selected (or can be NULL). For example, if you want a field to contain "A" or "B" or "C", you can define ENUM as ENUM('A', 'B', 'C') and only these values (or NULL) will populate the field. Probably the following are some advantages of ENUM data type: Compact data storage can be observed in situations where the column has a limited set of possible values. The specified string as input value is automatically encoded as a number. Numbers are converted back to corresponding strings in query results
