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",...);
