I found the h file in the postgres source and included in my build path, but
many errors.

Dunno if there's a better method - I would be inclined to loop round
con.Errors.Count though - maybe something like:

For X = 1 To con.Errors.Count
    set Error = con.Errors.Item(X - 1)
    'take the error code from SQL Server
    ErrCode = Error.NativeError
    response.Write(cstr(Error.Description))
End If
Response.End

Yeah, I can't see anything obviously wrong in it. A few things to
consider though:

- ASP seems to be retrieving data as SQL_C_CHAR, which means it's
getting raw data, not UCS2 converted from UTF8.

- ASP is retrieving data in 32KB chunks, so it would probably be worth
making sure max_long_varchar is at least that.

- Some data (quotes and such) doesn't look so good. Could it have been
pasted from MS Word or similar?

- Are you compiling the driver yourself? If so how? It seems to be using
the old comms layer, not libpq (which I'm no longer working on). The
giveaway is lines like the following which are for debugging the network
protocol:

connecting to the server socket...
connection to the server socket succeeded.
sizeof startup packet = 292
sent the authentication block.
sent the authentication block successfully.
gonna do authentication
read 15, global_socket_buffersize=8192
auth got 'R'
areq = 0
auth got 'K'
auth got 'Z'

All this is now encapsulated in libpq, which doesn't log what it's
doing.

To fix this, compile on the command line:

nmake /f win32.mak

This should ensure you get the default libpq build. If you're doing this
in an IDE, make sure USE_LIBPQ is defined!

Regards, Dave.
