Description¶

TMemoField is the class used when a dataset must manage memo (Text BLOB) data. (TField.DataType equals ftMemo). It initializes some of the properties of the TField class. All methods to be able to work with memo fields have been implemented in the TBlobField parent class.

It should never be necessary to create an instance of TMemoField manually, a field of this class will be instantiated automatically for each memo field when a dataset is opened.
