APPLIES TO

Microsoft Host Integration Server 2000 Standard Edition
Microsoft Host Integration Server 2000 Service Pack 1

SYMPTOMS

When you try to retrieve data by using the Microsoft Host Integration Server 2000 DB2OLEDB driver through a linked server from AS/400, you may receive an error that is similar to the following:

Server: Msg 7347, Level 16, State 1, Line 2
OLE DB provider 'DB2OLEDB' returned an unexpected data length for the fixed-length 
column '[DB2OLEDB].COLUMN1'. The expected data length is 40, while the returned 
data length is 0.
OLE DB error trace [Non-interface error: Unexpected data length returned for the 
column: ProviderName='DB2OLEDB', TableName='[DB2OLEDB]', ColumnName='COLUMN1', 
ExpectedLength='40', ReturnedLength='0'].

CAUSE

The Host Integration Server DB2OLEDB driver always overrides the column host character code set identifier (CCSID) with the late descriptor CCSID. If the late descriptor CCSID is 65535 (a binary type) and if the BinAsChar parameter is set to yes (convert all binary data to character data), the data conversion fails because 65535 is not a valid CCSID. This hotfix changes the host CCSID from 65535 to the default mixed-byte host CCSID.

Note Typically, this problem only occurs if the binary data is in the double-byte character set (DBCS).
