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
