Q125226: PRB: ODBC Reserved Word in a RFX Function Causes Syntax Error

Article: Q125226
Product(s): Microsoft C Compiler

-------------------------------------------------------------------------------
The information in this article applies to:

- The Microsoft Foundation Classes (MFC), included with:
   - Microsoft Visual C++, versions 1.50, 1.51 
   - *EDITOR Please do not choose this product*Microsoft Visual C++ 32-bit Edition* use 241, 265, 225, version 2.0

SYMPTOMS
========

An attempt to update a data source produces a command failed message box and MFC
Trace output:

  Syntax error in UPDATE statement.
  State:37000,Native:-3503,Origin:
  [Microsoft][ODBC Microsoft Access 2.0 Driver]

CAUSE
=====

Using an ODBC reserved word as the second parameter (char* szName) in an RFX
function causes the syntax error. The parameter represents the table's column
name. For example, the following code causes the error:

  void CMyRecordset::DoFieldExchange(CFieldExchange *pFX)
  {
  ...

    RFX_Date(pFX, "date", ...); // error "date" is ODBC reserved word!

  ...
  }

NOTE: Another scenario that will cause a similar error is caused by using a
reserved Access word for a table name, then trying to insert the table via MFC
and ODBC.

RESOLUTION
==========

Implement one of the following solutions:

- Change the name of the column in the data source's table. For example, change
  DATE to BIRTHDATE. DATE is a reserved word.

-or-

- Enclose the column name in square brackets when you use it in the RFX
  function in CRecordset::DoFieldExchange. For example:

  change this:

        RFX_Date (pFX, "Date",...);

  to this:

        RFX_Date(...,"[Date]",...);

-or-

- Qualify the column name with a table name (as MSQuery does) in the RFX
  function in CRecordset::DoFieldExchange. For example,

  Change this:

        RFX_Date(..., "Date",...);

  to this:

        RFX_Date(..., "table1.Date",...);
