It seems to me that the -w for isql does not work.  I am using release 10.0.4 or 11.1.1 of isql and it always truncates my output row to 258 bytes.  Can  somebody please comfirm this.  Thanks.

I can demonstrate that it works properly on Solaris.  It is probably your terminal that is
truncating the output (bcp wraps output rather than truncates it).

Is this on a UNIX box?  What kind of terminal are you using (xterm, sun, vt100, etc.)

Try this:

isql -Usa -P << EOF
use tempdb
go
create table isqltest(a char(255), b char(255), c char(255))
go
insert isqltest values ("a", "b","c")
go
exit
EOF
isql -Usa -P -w900 -o foobar.out << EOF
select * from tempdb..isqltest
go
exit
EOF
cut -c 240-260 foobar.out
cut -c 500-520 foobar.out

The first "cut" should show the "b" on the first line,
the second "cut" should show the "c".

I am using Solaris 2.5.1 and TERM=vt100.  When I try changing TERM to xterm same problem occurs.  Does not appear to be the TERM setting.  Any other ideas?

Thanks

This is one column that I am selecting.  The column is a shell script that will be run by the shell.  The column is like this
select
      "cd "+s.src_dir+"@"+"if test -f "+s.src_file+"@"+"do something etc@"

The @ symbols are turned into newlines and then the ouput is fed to ksh for execution.  Maybe one column has a restriction of 258.

Yes, that was the problem.  By breaking the select line up into columns by adding commas makes it work.  For example:
select
      "cd "+s.src_dir+"@",
      "if test -f "+s.src_file+"@",
      "then@",
      "      do something@",
      "fi@"

Oh, yes.  An individual column cannot contain more than 255 characters, max.

You could probably rewrite this asfollows (note that it is good form to
name all your columns; starting the column names with
"--" converts them into non-executable comments for the shellscript):

select
"cd "+s.src_dir+"@" as "--",
"if test -f "+s.src_file+"@" as "---",
"do something etc." + "@" as "----"
