Description
Use TSQLMemBlobStream to access or modify the value of a BLOB field object. BLOB field objects are TBlobField objects and descendants of TBlobField such as TGraphicField and TMemoField. BLOB fields use BLOB streams to implement a lot of of their data access properties and methods.
TSQLMemBlobStream allows objects to write to or read from BLOB field data of any type by means of using the uniform stream interface.To use a BLOB stream, create an instance of TSQLMemBlobStream, use the methods of the stream to read or write the data, and then free the BLOB stream. Do not use the same instance of TSQLMemBlobStream to access data from more than one record. Instead, create a new TSQLMemBlobStream object every time you need to read or write BLOB data on a new record.
