Non English Characters

Hi,
We are developing a small web interface to a local ERP software, which
uses SQL Server 2000 as database. The database uses SQL_Latin1_CP1
collation, and the fields are varchar (not nvarchar), however, the main
program inserts and reads non-English (Turkish) characters into these
columns. However, when we connect to database with ADO.NET, these
characters are not read correctly. (The situation is same when I check
tables with Enterprise Manager and Query Analyzer)

In a past situation (which was about a Win32 application), I have heard
about character conversion behaviour of ADO (and many other DB
libraries) and solved that problem using BDE instead of ADO, so that
the connection is made via DB-Library instead of OLEDB.

But this way cannot be applied to my ASP.NET situation, and there is NO
way to change database collation. Must I use a ADO.NET property, or use
another provider, or maybe another library? Any advices? Thanks...

Set your culture settings in your web.config file for the appropriate code
set that you use. This should solve the problem. You can also cast the
characters to ASCII by doing this (courtesy or Erland Sommerskog)

SELECT convert(varchar(6), N'ÇIGDEM' COLLATE Cyrillic_General_CS_AS)

A couple more thoughts are you storing the strings in nVarchar(20) data type
columns. Also if you use Erland's method you will loose the Turkish
characters if you store them using his technique but the searching should
work.

Hi, thanks for your interest.
Changing culture setting did not help, also there is no chance to
change data type of columns, they are varchar, not nvarchar.
Character conversion of database libraries and using a DB-Library based
API (in my previous example I'd chosen BDE) was Mr.Erland's
recommendation also :) However I cannot find a similar solution for
ASP.NET

Hi,
Choosing ODBC provider rather than OLEDB, and turning of character
translation option solved my problem.
