James,
Thanks for the response.  I guess I would have called it a
char or string type, but I understand.

The bcp command below is working now writing to a Sybase DB (ASE 12.0).  I'm
trying to use FreeTDS to replace the underlying libs and still use our
existing Perl code with little modification to target the new MS SQL Server
2000 DB.

In regards to your question below, I had intended to use the DBD::Sybase but
then found that Sybperl 
supported CTlib.  I stubbed out the method in CTlib.xs that used
blk_describe() and then I was able to get the code to compile.

The source I have uses Sybase::CTlib, so this was a simpler way to get done.
This source creates a bcp command string and executes it like an exec
function vs doing it programmatically.  However, right now the freebcp is
not working.

As I mentioned below, it would seem to me that this simple text should be
able to be inserted into the new MS SQL Server 2000 DB.  However the freebcp
man page states that the -e option is not current supported, thus I'm not
getting any error output, with the exception of the tdsdump.txt file. The
latter file will take some time for me to decode since I assume this is raw
TDS responses.

Another note in the man page is:
     Currently, there is  no  support  for  text  data  types  in
     freebcp, when SQL Server 2000 is the target database.

But above this it mentions using TDS 8.0 with SQL Server 2000.  So I'm not
sure what's right here.
Right now to be compatible with FreeTDS, I have compiled the source with
TDSVER 7.0.  In addition, the columns are numeric(10,0), datetime,
varchar(255), float()x3, and int.  This *should* work.

I looking at both Sybase and MS description of the bcp command options, I
think I have everything right. I'm also writting to an empty database, with
the fields setup by our DBA.  Not sure if this would be an issue though.

After reading the MS and Sybase web pages on bcp command line syntax, I
think what's missing the the input format, mainly the bcp.fmt file.  I'm not
sure where this file belongs wrt freebcp though... I assume it will be in
the freetds install path or ~/usr/local/etc.  I'll have to look for
tomorrow.

thanks for your help,
jd wilson

Hi John, 

"text" there refers to the server's column's datatype.  As distinguished
from int, varchar, float, etc.

Yes.

Have a look at bcp.err.  That should show you any rows that failed, and
why.

Verbose is on by default.  It's also off by default. ;)

We emulate Sybase's utility's behavior fairly closely, I believe.

If you don't specify an error file, you don't get much feedback, it's
true.  You *did* specify an error file (bcp.err).  In it, you should find
information about every row that failed to load.  If you don't, that would
be a bug.  

Are you over the hump with DBD::Sybase?
