I make a DataSet and DataTable in C# and then make a report for a SQL Server DB (I Use Report Viewer). I need to search Value field in DataBase when my Value is English Like "test" every thing is be OK, but when my value is Arabic\Persian\Farsi the report viewer dosen't show me anything.

My query is this:

SQL

SELECT DetailsProducts.DarSad, Materials.Material, Products.Product
FROM DetailsProducts INNER JOIN
    Materials ON DetailsProducts.MaterialID = Materials.ID INNER JOIN
    Products ON DetailsProducts.ProductID = Products.ProductID
WHERE (Products.Product = @Product)

When I need one value I can use this query:

SQL

SELECT DetailsProducts.DarSad, Materials.Material, Products.Product
FROM DetailsProducts INNER JOIN
    Materials ON DetailsProducts.MaterialID = Materials.ID INNER JOIN
    Products ON DetailsProducts.ProductID = Products.ProductID
WHERE (Products.Product =N'بطری') //(Bottle = بطری)

It is OK, but this " N'exp' " dose not work when I Use Parameters. How can I fix this?

I just did a test and works for me

Sp...

SQL

CREATE PROCEDURE spSelect @name nvarchar(40)
AS
BEGIN
    select *
    from employees
    where name  =@name

END

Calling....

either spSelect N'بطری' 
or EXECUTE spSelect @name = N'بطری'

You may have to set the following for you SQLcommand Object

parameter.SqlDbType = SqlDbType.NVarChar;
