ELOQUENCE B.07.10 - patch PE71-0804110
----------------------------------------------------------------------
This patch provides enhancements and/or defect fixes for the Odbc.DLL
program as released with Eloquence B.07.10. This patch will be
integrated in the Eloquence B.07.10 release.
Eloquence B.07.10 must be installed before applying this patch.

Patch PE71-0804110
------------------
Platforms: All
* Added the SetTextColumnSize procedure to specify the default and
maximum size for text columns.
CALL DLL Odbc("SetTextColumnSize",DefaultSize,MaxSize)
DefaultSize specifies the size the Odbc.DLL should use for text
columns when the ODBC driver does not specify a column size.
MaxSize specifies the maximum size for text columns the Odbc.DLL
should use. Both must be between 1 and 32767. DefaultSize must
not be greater than MaxSize.
By default, both DefaultSize and MaxSize are set to 1024.
* The Prepare or ExecDirect procedures could return ERROR 2 due to
a memory allocation failure if the ODBC driver specified a huge
size for a text column.
For example, the SQL Server ODBC driver may return a column size
of 2.147.483.647 bytes for a LONGVARCHAR column, which is the
theoretical LONGVARCHAR column size limit. The Odbc.DLL then tries
to allocate a buffer big enough to hold this column size, causing
a memory allocation failure.
The size of the allocated buffer is now limited to the maximum
size for a text column, which is 1024 by default but may be
configured with the SetTextColumnSize procedure.
* Changed the Windows file version to "7.1.0.11"
Patch PE71-0802280
------------------
Platforms: All
* The GetError procedure now traverses up the error stack in the
ODBC driver manager and the ODBC driver. Previously, only the
error information from the current context was retrieved.
For example, in a connection context the connection related
error information and in a statement context the statement
related error information was retrieved. This way, in rare
cases an error message could be missed, for example if the
ODBC driver generates a connection related error message in
a statement context.
* Changed the Windows file version to "7.1.0.10"
Patch PE71-0710250
------------------
Platforms: All
* Using the Fetch procedure with an XPACK buffer could result in
a wrong XPACK encoding, causing ERROR 204 on XUNPACK.
String variable names derived from column titles could become
one character too long.
* Changed the Windows file version to "7.1.0.9"
Patch PE71-0710160
------------------
Platforms: All
* The SetParam procedure did not work as expected.
* Changed the Windows file version to "7.1.0.8"
Patch PE71-0701090
------------------
Platforms: All
* Worked around an incompatibility in the FreeTDS ODBC driver that
does not support the SQLDescribeParam() ODBC function.
If the SQLDescribeParam() ODBC function is not supported, the
data type of a SQL query parameter is unknown. The Odbc.DLL now
handles this by binding the parameter at a later stage when the
application defines the data type.
As a consequence, the application should take care to provide
an appropriate parameter data type if the FreeTDS ODBC driver
is used, otherwise a data type mismatch error may result.
* Changed the Windows file version to "7.1.0.7"
