Hello,
  I am evaluating freebcp as a replacement to bcp (Sybase) while 
connecting to MS Sql Server 2008.  My problem is that when I bcp out a 
table even if I specify a format file, the output does not come out in 
fixed length as it did with bcp. 

Here is an example:

Table:
create table testbcp
(
        term_code               char(3)         NOT NULL,
        cbs_term_code           char(6)         NOT NULL,
        description             char(10)        NULL,
        last_update_date        datetime        NULL
)

Format file:
10.0
4
1       SYBCHAR 0       3       ""      1       term_code
2       SYBCHAR 0       6       ""      2       cbs_term_code
3       SYBCHAR 0       10      ""      3       description
4       SYBCHAR 0       24      "\n"    4       last_update_date

Output when calling freebcp testbcp out testbcp.dat -f testbcp.fmt -S 
SERVER -U USERNAME -P PW

093200901TESTING DE
094200902TEST2009-08-04 16:28:11.780
092200906NO DESC2009-08-04 16:28:11.780

But it should be fixed length like this:
093200901TESTING DE
094200902TEST             2009-08-04 16:28:11.780
092200906NO DESC     2009-08-04 16:28:11.780

For some reason it is not padding with spaces according to the format 
file like the Sybase bcp tool does.
Can anyone help me?

Hello,

 

It seems host process is currently hard coded to 37876 if using TDS <= 5
(eg Sybase):

% grep 37876 src/tds/login.c

        tds_put_login_string(tds, "37876", TDS_MAX_LOGIN_STR_SZ);
/* host process */

 

% tsql -Ufoo -SSYB1 -Pbar

...

1> select hostprocess from sysprocesses where spid = @@spid

2> go

hostprocess

37876

^Z

 

% ps -ef | grep tsql | grep -v grep

   woodd  2990  2832   0 00:38:09 pts/140     0:00 tsql -Ufoo -SSYB1
-Pbar

 

After applying the patch below:

 

% tsql -Ufoo -SSYB1 -Pbar

...

1> select hostprocess from sysprocesses where spid = @@spid

2> go

hostprocess

23294 

^Z

 

% ps -ef | grep tsql | grep -v grep

   woodd 23294 23233   0 00:41:47 pts/17      0:00 tsql -Ufoo -SSYB1
-Pbar

As the UG says, these flags provide a small degree of compatibility.  In
the case of msdblib, it adjusts the date structure; sybase-compat adds a
symbol.  

So, no, you don't need --enable-msdblib to connect to a Microsoft server;
you need it only if you're working with code that expects Microsoft's
db-lib conventions.  (That's why it's calls msdblib and not, say, ms-tds.)
 Sybperl, on the contrary, expects Sybase db-lib conventions.

Well, it *could* be.  Easiest is to rebuild FreeTDS without those two
flags.  Modifying Sybperl might possibly be of some service, in that it
would facilitate using Fedora as-is, or even potentially using Microsoft's
library.
