Since I use VC4.0, which includes the old sql include files, there is not a
problem.

On VC5.0, the newer odbc 3.0 sql include files are used.  Therefore, the driver
needs to specify the ODBCVER explicitly, otherwise it defaults to 3.0 which is
the problem.

Solution:

1.  Somewhere in "psqlodbc.h", add the following line:

# define ODBCVER   0x0200

2. In connection.h, move the #include "psqlodbc.h" to prior to #ifdef HAVE_IODBC

3. In statement.h, move the #include "psqlodbc.h" to prior to #ifdef HAVE_IODBC

4. In convert.c, add the line #include "psqlodbc.h" prior to #ifdef HAVE_IODBC


As for the anachronism thing, you can either ignore it or just remove the
SQL_API keyword.


I will try to get these corrections into the next release.

Thanks,

Byron
