Description
TBinaryField represents an untyped binary field in a dataset.
Data.DB.TBytesField inherits from Data.DB.TBinaryField. All content below this line refers to Data.DB.TBinaryField.
TBinaryField represents an untyped binary field in a dataset.
TBinaryField encapsulates the fundamental behavior common to untyped binary fields. In addition to the properties, methods, and events common to all fields that are introduced by the TField class, TBinaryField reimplements the properties that are used to read and write binary data from or to the underlying database table.
If you use the Fields editor at design time to create a persistent field component for the binary field, you can access it by name at runtime. When using dynamic field components, you can access the TBinaryField instance using the dataset's Fields property or FieldByName method.
