The information in this article applies to:

-------------------------------------------------------------------------------

SYMPTOMS
========

Using the Microsoft ODBC Driver for Oracle (build 2.73.728303) that ships with
MDAC 1.5c causes a SQL_SUCCESS_WITH_INFO message and a "Data Truncated" error
when trying to store LONG RAW data with SQLPutData and using SQLBindParameter
with the ColumnSize (6th Parameter) set to 0 or less than the actual length of
the data. This occurs even though SQLGetInfo for SQL_NEED_LONG_DATA_LEN returns
a "No". Also, no data is written to the LONG RAW field.

The problem occurs if you bind the parameter as a SQL_C_BINARY and SQL_BINARY
like this:

  g_rc = SQLBindParameter(g_hstmt, 1, SQL_PARAM_INPUT, SQL_C_BINARY,
  SQL_BINARY, 0, 0, NULL, 0, &cbVal1);

RESOLUTION
==========

Make the Columnsize parameter of the SQLBindParameter equal to or greater than
the actual value of the data length passed in SQLPutData. Upgrade to the
Microsoft Oracle ODBC Driver available in Visual Studio 6.0 or Microsoft Data
Access Components version 2.0 or later. You can download the MDAC Components
from the following Web address:

STATUS
======

This bug has been fixed in version 2.573.2927 of the Microsoft Oracle ODBC
Driver.
