I have a problem in SQL Server 2000 when searching for a term in farsi

Question

I have a problem in SQL Server 2000 with farsi search.

I have a table with nvarchar fields with unicode (farsi) values and need to search content of that with unicode (farsi) text.

I am using

select * from table1
where fieldname like '%[farsi word]%'

My farsi word is exist but return 0 row.

What can I do?

thanks all.

If you're using NVARCHAR fields, you should also use Unicode when searching! You do this by prepending a N before your search term:

select * from table1
where fieldname like N'%[farsi word]%'

Also: be aware the if your search term begins with a % wildcard, you've basically disabled all use of any indices there might be to speed up your search. Using LIKE %...% for searching will always result in a pretty slow table scan....
