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 <field name>

CAUSE

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