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

ID: Q125226

The information in this article applies to:

The Microsoft Foundation Classes (MFC), included with:
- Microsoft Visual C++ for Windows, versions 1.50, 1.51
- Microsoft Visual C++ 32-bit Edition, 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.

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]",...); 
```

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",...); 
```
