Cannot convert utf-8 in Stored Procedure SQL - sql

Question

I'm stuck in the utf-8 format. I used CAST or CONVERT USING UTF-8. Even I set character N in front of query string but it's still not working.
My stored procedure:
ALTER PROCEDURE [dbo].[SPC_SP_HSDXTChinh_BangSo4_Fake]
#idDuAn NUMERIC(18, 0),
#idGoiThau NUMERIC(18, 0),
#idDonVi INT
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
DECLARE #resultString NVARCHAR(MAX);
DECLARE #queryString NVARCHAR(MAX);
DECLARE #Str_TinhHopLe NVARCHAR(255), #Str_DanhGia NVARCHAR(255), #Str_XepHang NVARCHAR(255);
SET #Str_TinhHopLe = 'N''Kết quả đánh giá tính hợp lệ của HSĐXTC''';
SET #Str_DanhGia = 'N''Giá đánh giá''';
SET #Str_XepHang = 'N''Xếp hạng các HSDT''';
SELECT #resultString = COALESCE(#resultString + ',', '') + RES.TenNhaThau
FROM (
SELECT '[' + TenNhaThau + ']' AS TenNhaThau
FROM [SPC_fn_HSDXTChinh_NhaThau_CoTinhHopLe] (#idDuAn, #idGoiThau, #idDonVi)
) RES
--PRINT #resultString
PRINT #Str_TinhHopLe;
SET #queryString = '
SELECT *
FROM (
SELECT 1 AS STT,' + #Str_TinhHopLe + ' AS NoiDung,
CAST(RES.TenNhaThau AS NVARCHAR(255)) AS TenNhaThau,
CAST(RES.KetQuaDanhGia AS VARCHAR(25)) AS KetQuaDanhGia
FROM [SPC_fn_HSDXKThuat_BangSo4] (' + CAST(#idDuAn AS VARCHAR(20)) + ',' + CAST(#idGoiThau AS VARCHAR(20)) + ',' + CAST(#idDonVi AS VARCHAR(10)) + ') RES
) SRC
PIVOT(MAX(KetQuaDanhGia) FOR TenNhaThau IN (' + #resultString + ')) P
UNION ALL
SELECT *
FROM (
SELECT 2 AS STT
,' + #Str_DanhGia + ' AS NoiDung,
CAST(RES.TenNhaThau AS NVARCHAR(255)) AS TenNhaThau,
CAST(RES.GiaTri AS VARCHAR(25)) AS GiaTri
FROM [SPC_fn_HSDXKThuat_BangSo4] (' + CAST(#idDuAn AS VARCHAR(20)) + ',' + CAST(#idGoiThau AS VARCHAR(20)) + ',' + CAST(#idDonVi AS VARCHAR(10)) + ') RES
) SRC2
PIVOT(MAX(GiaTri) FOR TenNhaThau IN (' + #resultString + ')) P
UNION ALL
SELECT *
FROM (
SELECT 3 AS STT
,' + #Str_XepHang + ' AS NoiDung,
CAST(RES.TenNhaThau AS NVARCHAR(255)) AS TenNhaThau,
CAST(ROW_NUMBER() OVER(ORDER BY GiaTri) AS VARCHAR(25)) AS XepHang
FROM [SPC_fn_HSDXKThuat_BangSo4] (' + CAST(#idDuAn AS VARCHAR(20)) + ',' + CAST(#idGoiThau AS VARCHAR(20)) + ',' + CAST(#idDonVi AS VARCHAR(10)) + ') RES
) SRC2
PIVOT(MAX(XepHang) FOR TenNhaThau IN (' + #resultString + ')) P
';
PRINT #queryString;
EXEC (#queryString);
END
A part of output messages after run stored:
SELECT
1 AS STT,
N'K?t qu? dánh giá tính h?p l? c?a HSÐXTC' AS NoiDung,
CAST(RES.TenNhaThau AS NVARCHAR(255)) AS TenNhaThau,
CAST(RES.KetQuaDanhGia AS VARCHAR(25)) AS KetQuaDanhGia
FROM
[SPC_fn_HSDXKThuat_BangSo4] (60006000000000166, 60006000000000347, 60006) RES
You can see error text: N'K?t qu? dánh giá tính h?p l? c?a HSÐXTC'.
I want to output: Kết quả đánh giá tính hợp lệ của HSĐXTC
How can I fix this?

Answer 1

Change these lines in your procedure:
SET #Str_TinhHopLe = N'Kết quả đánh giá tính hợp lệ của HSĐXTC';
SET #Str_DanhGia = N'Giá đánh giá';
SET #Str_XepHang = N''Xếp hạng các HSDT';
