The information in this article applies to:
- Microsoft ODBC Driver for SQL Server, version 3.7
- Microsoft Data Access Components versions 2.5, 2.6
- Microsoft SQL Server 2000 (all editions)
- Microsoft SQL Server versions 7.0, 7.0 Service Pack 1, 7.0 Service Pack 2

SYMPTOMS
========
If a table has been created in SQL Server that contains column names of "C",
"CA" or "CAS", and if a statement is prepared that uses parameters against these
columns, attempting to call the SQLDescribeParam function for these parameters
generates the following error message:
42000 [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near
the keyword 'by'.
This error message occurs when you use SQL Server ODBC driver version 3.70.0820
(Microsoft Data Access Components [MDAC] 2.5, Microsoft Windows 2000) and later.
This error also occurs in the Microsoft SQL Server 2000 ODBC driver, version
2000.080.0194.00.
CAUSE
=====
In the call to SQLDescribeParam, a SQL statement is being constructed by the
driver to retrieve the parameter metadata. The driver checks to see if a CASE
function is included in this statement, and is incorrectly comparing the "C",
"CA" and "CAS" column names against the CASE keyword. The comparison returns
True, and the driver appends a GROUP BY clause on the end of the statement.
RESOLUTION
==========
To resolve this problem, obtain the latest service pack for Microsoft Data
Access Components 2.6. For additional information, please see the following
article in the Microsoft Knowledge Base:

09/11/2000 2000.80.203.0 28,742 bytes Odbcbcp.dll
WORKAROUND
----------
To work around this problem:
- If possible, do not include the names of the columns in the SQL statement.
For example, instead of using syntax like:
Insert into CATest (CA) values (?)
use the following:
Insert into CATest values (?, ?, ...)
-or-
- Concatenate the parameters directly into the SQL statement instead of using
parameter markers. For example, use the following syntax:
Insert into CATest (CA) values ('abc')
STATUS
======
Microsoft has confirmed this to be a problem in the Microsoft products that are
listed at the beginning of this article.
This problem was corrected in Microsoft Data Access Components (MDAC) 2.5 Service
Pack 2, MDAC 2.6 Service Pack 1, and MDAC 2.7.
MORE INFORMATION
================
This error occurs primarily when you construct INSERT statements, and when the
column names of "C", "CA" or "CAS" are included in the field list. The error
message does not occur if the SQL statement does not contain a field list.
An ODBC trace or a SQL Profiler trace shows that the driver's internal SELECT
statement has been incorrectly formed as:
Select CA from CATestgroup by
Because the SELECT statement is incorrectly formed, the error message occurs when
the statement is sent to the server for processing.
This fix is available for the Microsoft SQL Server 7.0 SP2 ODBC driver, and the
Microsoft SQL Server 2000 ODBC driver. NOTE: Please use the files in
SQL70_ColName_Fix.exe for SQL Server 7.0 and use the files in
SQL2000_ColName_Fix.exe for SQL Server 2000.
