ODBC driver reports wrong column data size for mediumblob columns.  It reports 65535 to MS CRecordset even the blob column is mediumblob columns.  CRecordset binds a 65535 bytes CByteArray to the mediumblob field to cause data truncated error.

How to repeat:
Create a table with mediumblob column then try to insert a data field with size greater than 65535 bytes to the table.  A CDBException will throw with "Data truncated" error.

Suggested fix:
Find in your ODBC drive source where 65535 or related constant is used, specially in function SQLDescribtCol function, to see it used to report precision for mediumblob column or not.  Fix it please.
