: after installing SQliteODBC use ADO through ODBC access Blob field in a SQlite database, check back ftbytes type, not ftblob types, using CreateBlobStream appear "invalid class typecast" error

Ftbytes - & gt; Fixed number of bytes (binary storage)

In other SQL Server database operation is normal, return ftblob, and can use CreateBlobStream read blob stream,

Problem: 1, SqliteODBC read how to return to the ftblob blob field in Delphi;
2, return how to switch to TMemoryStream ftbytes types, this type of data size is fixed,

Not very with gratitude!
