EnumerationAttribute Class

Specifies how an enumerated type value is stored in the database.

Remarks

Apply this attribute directly above the enumerated type declaration (not on a field or property). Use TEnumMappingType.emInteger to store ordinal values, TEnumMappingType.emString to store the name of each enumerated value, or TEnumMappingType.emChar to store a single uppercase character per value. When using emChar or emString, supply the comma-separated mapped values in the same order as the enumerated type values.
