AS400 Linked Server - Error when performing UPDATE

[David Prowak <prowak@xxxxxxxxx>]

Hi,
I've got my AS400 setup as a linker server to my SQL Server 2005.

When I run a "simple" update (I am updating a char field), I get this error:

*OLE DB provider "MSDASQL" for linked server "AS400 HSGLIB" returned message
"Unspecified error".*

*OLE DB provider "MSDASQL" for linked server "AS400 HSGLIB" returned message
"[IBM][System i Access ODBC Driver][DB2 for i5/OS]SQL0440 - Routine
SQLSTATISTICS in SYSIBM not found with specified parameters.".*

*Msg 7311, Level 16, State 2, Line 1*

*Cannot obtain the schema rowset "DBSCHEMA_INDEXES" for OLE DB provider
"MSDASQL" for linked server "AS400 HSGLIB". The provider supports the
interface, but returns a failure code when it is used.*

Does anyone know what causes this error or what the workaround is?

TIA,

Dave
