Thanks for this James,

I've always been slightly uneasy about text columns, although I know they
have worked in the past.

Unlike you to be so imprecise :-)
If it were anyone else, I'd ask the following questions:

which version of freetds ?
which version of which database ?
freebcp or the dblibrary "sendrow" API ?
all text columns, or just very large ones ?

My version of freebcp works just fine.....

1> create table bill_bcp_text_test (col1 int not null, col2 text )

$ cat bill_bcp_text_test.txt
2       asdasdasdasda

$ freebcp MYDB..bill_bcp_text_test in bill_bcp_text_test.txt -c -S MYSERVER

Starting copy...

3 rows copied.

1> select * from bill_bcp_text_test
col1                col2
-------------------   -----------------------------------------------
                 1   ABCDEFGHIJKL<
                 2   asdasdasdasda
(3 rows affected)

My (production) version of freetds is, however, a "pre-iconv" snapshot of
So, I guess you're using something a little more up to date, and its gotten
broken.somewhere down the line...

I'll test my new code, and check out text columns specifically..
