SYMPTOMS
An application may use either the Microsoft Host Integration Server 2000 DB2OLEDB driver or the Microsoft ODBC Driver for DB2 to issue queries against an IBM DB2 database. When it does this, the provider may return an internal network library (NetLib) error. This error occurs when the provider processes an SQL Communication Area (SQLCA) structure that is split across two Query Answer Set Data (QRYDTA) replies. This problem is most likely to occur when the result set that is returned by DB2 contains an SQLCA warning structure at the beginning of each row of data.

The error message that is returned by the application may vary. For example, a Microsoft Visual Basic application may return the following error:

err.number = -2147217900 (80040e14)



CAUSE
This problem occurs because the Host Integration Server 2000 DB2OLEDB driver and the ODBC Driver for DB2 do not correctly handle an SQLCA structure that is split across multiple QRYDTA replies.



WORKAROUND
You may be able to work around this problem by modifying the query to correct the condition that causes the SQLCA warning.
