Description

Indicates that this is a BLOB field.

Use IsBlob when working with a TField object to determine whether it represents BLOB data. For example, before using the GetData or SetData method (which does not work with BLOB fields), call IsBlob to determine whether the method can be used. The IsBlob method for TBlobField always returns true.
