Проблема Django разрешения специальных символов в URL

Пример данных

CREATE table #Phonetype
( ptype_id INT,
 description VARCHAR(20)
 )
 INSERT INTO   #Phonetype
 SELECT 1,'HOME' UNION ALL
 SELECT 2,'WORK' UNION ALL
 SELECT 3,'CELL' 

CREATE table #Phone 
(phoID INT,
pho_PhoneNum BIGINT,
ptype_id INT)

INSERT INTO #Phone
SELECT 1,012313 ,1 UNION ALL
SELECT 2,0132465,2 UNION ALL
SELECT 3,1324654,3

Использование PIVOT на сервере Sql

DECLARE @Columns nvarchar(max),
        @IsnullColumns nvarchar(max),
        @Sql  nvarchar(max)


SELECT @Columns= STUFF((SELECT ', '+QUOTENAME([description]) FROM  #Phonetype t
INNER JOIN  #Phone  p
On t.ptype_id=p.ptype_id FOR XML PATH ('')),1,1,'')


SET @Sql='
SELECT [phoID], '+@Columns+'
FROM
    (   SELECT T.ptype_id, 
            [description],
            phoID,
            pho_PhoneNum
        FROM #Phonetype t
        INNER JOIN  #Phone  p
        On t.ptype_id=p.ptype_id

    ) AS SRC
 PIVOT 
   (MAX(pho_PhoneNum) FOR [description] IN('+@Columns+')
   ) AS PVT
'
PRINT @Sql
EXEC (@Sql)
