SYMPTOMS
When a Linked Server is configured to DB2/400 from Microsoft SQL Server by using the OLE DB provider for DB2, and a SELECT query is issued to retrieve data from a DB2/400 table that contains a DBCS fixed-length character field, the following error message may be returned:

OLE DB provider 'DB2OLEDB' returned unexpected length of data from fixed length field



CAUSE
The DB2 OLE DB Provider returns different values for the field length and the actual data size, which causes the SELECT to fail.
