列转行失败

[化境者]

SELECT     a.ID, (CASE e.Name WHEN 'AA' THEN CAST(b.czwt AS varchar) ELSE 'X' END) AS 'AA', 
                      (CASE e.Name WHEN 'BB' THEN CAST(b.czwt AS varchar) ELSE 'X' END) AS 'BB', 
                      (CASE e.Name WHEN 'CC' THEN CAST(b.czwt AS varchar) ELSE 'X' END) AS 'CC'
FROM         a INNER JOIN
                      b ON a.ID = b.XX_ID INNER JOIN
                      c ON b.hfz = c.ID INNER JOIN
                      e ON c.CJ = e.ID
GROUP BY a.ID
order by e.Name,b.czwt

各位大蝦！我上面的代码是列转行代码！帮忙看看怎么回事

数据类型：
a.id bigint
e.name varchar(50)
b.czwt bit
