Answer 1

這裏，試試這個，

SELECT a.dept_id, 
     NewTable.NameValues 
FROM (
      SELECT DISTINCT dept_ID 
      FROM tableA 
     ) a 
     LEFT JOIN 
     (
      SELECT dept_id, 
       STUFF((
        SELECT ', ' + [Name] 
        FROM tableA 
        WHERE (dept_id = Results.dept_id) 
        FOR XML PATH('')), 1, 1, '') AS NameValues 
      FROM tableA Results 
      GROUP BY dept_id 
     ) NewTable 
     on a.dept_id = NewTable.dept_id 
GO

這裏的另一個版本

SELECT a.dept_id, 
     SUBSTRING(d.nameList,1, LEN(d.nameList) - 1) ConcatenateNames 
FROM 
     (
      SELECT DISTINCT dept_id 
      FROM tableA 
     ) a 
     CROSS APPLY 
     (
      SELECT name + ', ' 
      FROM tableA AS B 
      WHERE A.dept_id = B.dept_id 
      FOR XML PATH('') 
     ) D (nameList) 
GO
