这可能会有所帮助

This might be helpful

DECLARE @CITIES VARCHAR(8000)  
SELECT @CITIES = COALESCE(@CITIES + ', ', '') + CITIES FROM Hotels

SELECT distinct HOTEL_NAME, @CITIES AS CITIES FROM Hotels

嗨杰克逊，

试试这个.....

Hi Jackson,

Try This.....

-- Table Creation
IF OBJECT_ID('TempDB..#HotelDtls') IS NOT NULL DROP TABLE #HotelDtls
CREATE TABLE #HotelDtls(HotelName VARCHAR(50), CityName VARCHAR(100))
-- Sample Data
INSERT INTO #HotelDtls(HotelName, CityName) VALUES('Pigion','QQ'),('Pigion','YY'), ('Pigion','ZZ')
-- Actual Data
SELECT HotelName, CityName FROM #HotelDtls
-- Required Output
SELECT HotelName,  
  REPLACE((SELECT  CityName AS [data()] 
           FROM #HotelDtls  
           WHERE b.HotelName=HotelName
           ORDER BY CityName FOR XML PATH('')),
          ' ', ', ') 'CityName'
FROM #HotelDtls b 
GROUP BY HotelName
