Well... empty not NULL... but for user_name is quite the same... I
don't think any system have a "" username!

I updated docuementation a bit. Usually the base requirement is to
configure a /etc/krb5.conf file and initialize a ticket with kinit.

You mean this:

I think all we need to do is add those things to the UG.  Not hard, and
lets us use other parts of NetBSD, too, if we want to.  

I'll do that in time for the release.

Thanks.

Since we can't specify client charset in a DSN-less configuration, I
reverted to using freetds.conf and I'm still getting str returned instead of
unicode.  My config files are now:

odbcinst.ini

[ODBC]
Trace                   = Yes
TraceFile               = /tmp/unixodbc.log

second query fails when querying sql server 2008

Hello,

I have FreeTDS installed on a 64 bit CentOS platform, connecting to a MS SQL Server 2008.

Configuration:
                tds version = 8.0

I connect using the following scenarios:

-----------------------------------------------
                Connect to isql
                Select * from sip_acc
                                (55 rows returned)
                Disconnect

-----------------------------------------------

                Connect to isql
                Select 1
                                (1 row returned)
                Select * from sip_acc
                                (0 rows returned)
                Disconnect

                NOTES:  Looking in the freetds.log file I see there are 55 rows returned.
token.c:2175:                rows_affected = 55
-----------------------------------------------

Any recommendations?
Thanks,

Re: second query fails when querying sql server 2008

Is there a setting that will force that?

If I connect to a Mysql database (using the standard Mysql odbc driver), I don't get the error.
Thanks,

Hi ,

You need to close the cursor.

I think I found a bug, but I don't think it's causing what you're seeing. 
It's only preventing me from helping you.  

I created a table as follows:

bsqldb -q -S$S -U$U -P$(password $S $U) <<SQL
create table test_utf8
	( id int IDENTITY
	, name nchar(10) not NULL
	, primary key (id)
	)
insert test_utf8 (name) values ('hallå')
insert test_utf8 (name) values ('adjö')
insert test_utf8 (name) values ('Århus')
go
SQL

(I hope those are readable in your mail client.)  

When I fetch these rows with bsqlodbc, I provoke an error:

$ printf "select * from test_utf8\ngo\n" | bsqlodbc -S$S -U$U -P$(password
$S $U)    
        id  name

SQLDescribeCol is correct.  It returns the logical size, the size as reported by the server.  The column size
is measured in characters, by definition; the server's storage requirements are not the client's
