bulk inserting uniqueidentifie r column

[bob.speaking]

Hi at all,
I'm trying to bulk insert a uniqueidentifie r column from unicode file.
In my file I have guid generated from c# application and they are
formatted in this way (separated by "|") :

guid | field1 | field2
fc0c0c42-438e-4897-96db-8b0489e873ef|fi eld1|field2

In my destination table I have three column:
id (uniqueidentifi er)
field1 (nvarchar)
field2 (nvarchar)

I use in bulk insert a format file like this :

9.0
3
1 SQLNCHAR 0 0 "|\0" 1 ID Latin1_General_ CI_AS
2 SQLNCHAR 0 0 "|\0" 2 Field1 Latin1_General_ CI_AS
3 SQLNCHAR 0 0 "|\0" 3 Field2 Latin1_General_ CI_AS

and I use this script

BULK INSERT [dbo].[KWTA2] FROM 'd:\WTA2.txt'
WITH (FORMATFILE = 'd:\wta2Format. FMT')

It doesn't work, it prints out
Msg 8152, Level 16, State 13, Line 2
String or binary data would be truncated.

I've also tried to specify in FMT file SQLUNIQUEID instead of SQLNCHAR
and it works perfectly but it imports another data. For example the
guid fc0c0c42-438e-4897-96db-8b0489e873ef became
00350031-0039-0033-3100-300030003000

Please can you help me?
Why sql converts alphanumerical GUID into only numbers ID?
How can I bulk insert GUID? (I didn't find anything googling around :
\ )

Thanks!

Bob

Does the file really consist of one single line?

Assuming that you have one record per line in the file, the terminator
for field 3 should be \r\0\n\0. What happens now is that Field2 in the
first record extends into the GUID in the second record, and then it
goes downhill from there.

I've also tried to specify in FMT file SQLUNIQUEID instead of SQLNCHAR
and it works perfectly but it imports another data. For example the
guid fc0c0c42-438e-4897-96db-8b0489e873ef became
00350031-0039-0033-3100-300030003000

SQLUNIQUEID is what you would use in a binary file. It's not applicable
here.

I'm sorry, cut and pasting sample text file I've removed the correct
syntax :\
In fact the last line has the terminator you specified. :)

I'm migrating this bulk insert frm sql server 2000... in 2005 this
doesn't work. Is it caused by more strictly rules in 2005 engine?
Is sql converting my "char" guid in binary?

Thanks for the prompt reply :)
