chinese characters with Unicode data types?

Hi,
I read that Unicode data types (like nchar or nvarchar)
support any characters of any language in the world. As we
need a database that supports many different languages, I
have tried to paste chinese characters into one table
field - although the field's data type is nvarchar, it
pastes only squares (instead of the chinese characters)
Can someone please help?
Thanks in advance,
BodoOne possibility is that the data is actually stored correctly in the
database, but the query tool you are using hasn't been configured to use a
font that defines glyphs for Chinese characters. Try using Query Analyzer
to both insert and view the data (don't use the "Show All Rows" view in
Enterprise Manager as the controls used in this view aren't Unicode aware).
Go to Tools --> Options --> Fonts tab, and select a font that supports
Chinese like "SimSun" or "Arial Unicode MS" for the "Results Text" and
"Results Grid" views.

checksum() of char, varchar, nchar, nvarchar, or sql_variant

Karam,
checksum and binary_checksum can be used for char, varchar, nchar, and
nvarchar. If you need it for sql_variant, you could convert the
sql_variant value to varbinary before applying the checksum or
binary_checksum. The following works fine for me (SQL Server 2000 sp3).
declare @.t table (
a char(10),
b nchar(10),
c varchar(10),
d nvarchar(10),
e sql_variant
)
insert into @.t values ('abc','def','ghi','jkl',cast(3.2 as sql_variant))
insert into @.t values ('abc','def','ghi','jkl',cast('mno' as sql_variant))
insert into @.t values ('abc','def','ghi','jkl',cast(PI() as sql_variant))
select
checksum(a),
checksum(b),
checksum(c),
checksum(d),
checksum(cast(e as varbinary(8000)))
from @.t

If you include a, b, c, d, and e in the output, it should look fine:
abc 34400 def 1132889051 ghi 40390
jkl -2087894091 3.2 135216
abc 34400 def 1132889051 ghi 40390
jkl -2087894091 mno 27535
abc 34400 def 1132889051 ghi 40390
jkl -2087894091 3.1415926535897931 200148684
You should be aware of the fact that CHECKSUM is not guaranteed to
return different values from different input. There are only
~4000000000 possible checksum values, but far more possible input values.
