如何在SQL SERVER 2008 R2中逐行显示单个列中的多个值？

Question

I'm using SQL SERVER 2008 R2. I want to get the multiple values and show it in the single column with line by line at the same time, if the values present otherwise it shows some values and might be the possibility of '12 values' on a single column.

For Example, The screen Shot below, it shows records for the same data except the comments. I want to display as the single record, but the comments should show the both values that is ASN Timeliness, ASN Accuracy, problem reports . The three values are displayed line by line using the same shipsite "0096a".

My sample query,

SELECT 
    D30.SPGD30_SHIP_SITE_C AS SHIPSITE,  
    D30.SPGD30_RATING_MONTH_Y AS RATINGMONTH,  
    D30.SPGD30_PRIOR_SCORE_R AS PRIOR, 
    D30.SPGD30_REVISED_SCORE_R AS REVISED,  
    CASE WHEN (CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 ) THEN CONVERT( VARCHAR(8), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X AS DATETIME) , 1) ELSE D30.SPGD30_TRACKED_ADJUSTMENT_X END ADJUSTMENTS,  
    J02.SPGJ02_MSG_CODE_X AS COMMENTS,  
    D30.SPGD30_LAST_TOUCH_Y AS LASTUPDATED,  
    D30.SPGD30_LAST_TOUCH_C AS LASTUPDATEDCDSID   
FROM  
    CSPGD30_TRACKING D30, 
    CSPGD31_TRACKING_RATING_ELEMNT D31,  
    CSPGA04_RATING_ELEMENT_MSTR A04 , 
    CSPGJ02_MSG_OBJ J02  
WHERE  
    D30.SPGA02_BUSINESS_TYPE_C = D31.SPGA02_BUSINESS_TYPE_C  
AND 
    D30.SPGA03_REGION_C = D31.SPGA03_REGION_C  
AND 
    D30.SPGD30_SHIP_SITE_C = D31.SPGD30_SHIP_SITE_C  
AND 
    D30.SPGD30_RATING_MONTH_Y = D31.SPGD30_RATING_MONTH_Y  
AND 
    D30.SPGD30_TRACKED_ADJUSTMENT_X = D31.SPGD30_TRACKED_ADJUSTMENT_X  
AND 
    D30.SPGD30_LAST_TOUCH_Y = D31.SPGD30_LAST_TOUCH_Y  
AND 
    D31.SPGA04_RATING_ELEMENT_D = A04.SPGA04_RATING_ELEMENT_D  
AND 
    A04.SPGJ02_MSG_K = J02.SPGJ02_MSG_K  
AND 
    D30.SPGA02_BUSINESS_TYPE_C = 'serv'  
AND 
    D30.SPGA03_REGION_C = 'ap'  
AND 
    D30.SPGD30_SHIP_SITE_C = '0134a'  
ORDER BY   
    D30.SPGD30_SHIP_SITE_C ASC  ,
    D30.SPGD30_RATING_MONTH_Y DESC  ,
    D30.SPGD30_LAST_TOUCH_Y DESC 

Answer 1

I see two ways that you can do this.

First you can use FOR XML PATH and STUFF in a correlated subquery. This will concatenate the values from the CSPGJ02_MSG_OBJ into a single string:

SELECT D30.SPGD30_SHIP_SITE_C AS SHIPSITE,  
    D30.SPGD30_RATING_MONTH_Y AS RATINGMONTH,  
    D30.SPGD30_PRIOR_SCORE_R AS PRIOR, 
    D30.SPGD30_REVISED_SCORE_R AS REVISED,  
    CASE WHEN (CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 ) THEN CONVERT( VARCHAR(8), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X AS DATETIME) , 1) ELSE D30.SPGD30_TRACKED_ADJUSTMENT_X END ADJUSTMENTS,  
     STUFF((SELECT distinct '+ ' + J02.SPGJ02_MSG_CODE_X
            from CSPGJ02_MSG_OBJ J02
            where A04.SPGJ02_MSG_K = J02.SPGJ02_MSG_K 
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,2,'') COMMENTS,
    D30.SPGD30_LAST_TOUCH_Y AS LASTUPDATED,  
    D30.SPGD30_LAST_TOUCH_C AS LASTUPDATEDCDSID   
FROM CSPGD30_TRACKING D30
INNER JOIN CSPGD31_TRACKING_RATING_ELEMNT D31
    ON D30.SPGA02_BUSINESS_TYPE_C = D31.SPGA02_BUSINESS_TYPE_C  
    AND D30.SPGA03_REGION_C = D31.SPGA03_REGION_C  
    AND D30.SPGD30_SHIP_SITE_C = D31.SPGD30_SHIP_SITE_C  
    AND D30.SPGD30_RATING_MONTH_Y = D31.SPGD30_RATING_MONTH_Y  
    AND D30.SPGD30_TRACKED_ADJUSTMENT_X = D31.SPGD30_TRACKED_ADJUSTMENT_X  
    AND D30.SPGD30_LAST_TOUCH_Y = D31.SPGD30_LAST_TOUCH_Y  
INNER JOIN CSPGA04_RATING_ELEMENT_MSTR A04
    ON D31.SPGA04_RATING_ELEMENT_D = A04.SPGA04_RATING_ELEMENT_D  
WHERE D30.SPGA02_BUSINESS_TYPE_C = 'serv'  
    AND D30.SPGA03_REGION_C = 'ap'  
    AND D30.SPGD30_SHIP_SITE_C = '0134a'  
ORDER BY D30.SPGD30_SHIP_SITE_C ASC, D30.SPGD30_RATING_MONTH_Y DESC, D30.SPGD30_LAST_TOUCH_Y DESC;

The second method is to use a CROSS APPLY with FOR XML PATH :

SELECT D30.SPGD30_SHIP_SITE_C AS SHIPSITE,  
    D30.SPGD30_RATING_MONTH_Y AS RATINGMONTH,  
    D30.SPGD30_PRIOR_SCORE_R AS PRIOR, 
    D30.SPGD30_REVISED_SCORE_R AS REVISED,  
    CASE WHEN (CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 ) THEN CONVERT( VARCHAR(8), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X AS DATETIME) , 1) ELSE D30.SPGD30_TRACKED_ADJUSTMENT_X END ADJUSTMENTS,  
    left(J02.comments, LEN(J02.comments)-1) AS COMMENTS,
    D30.SPGD30_LAST_TOUCH_Y AS LASTUPDATED,  
    D30.SPGD30_LAST_TOUCH_C AS LASTUPDATEDCDSID   
FROM CSPGD30_TRACKING D30
INNER JOIN CSPGD31_TRACKING_RATING_ELEMNT D31
    ON D30.SPGA02_BUSINESS_TYPE_C = D31.SPGA02_BUSINESS_TYPE_C  
    AND D30.SPGA03_REGION_C = D31.SPGA03_REGION_C  
    AND D30.SPGD30_SHIP_SITE_C = D31.SPGD30_SHIP_SITE_C  
    AND D30.SPGD30_RATING_MONTH_Y = D31.SPGD30_RATING_MONTH_Y  
    AND D30.SPGD30_TRACKED_ADJUSTMENT_X = D31.SPGD30_TRACKED_ADJUSTMENT_X  
    AND D30.SPGD30_LAST_TOUCH_Y = D31.SPGD30_LAST_TOUCH_Y  
INNER JOIN CSPGA04_RATING_ELEMENT_MSTR A04
    ON D31.SPGA04_RATING_ELEMENT_D = A04.SPGA04_RATING_ELEMENT_D  
CROSS APPLY
(
    select J02.SPGJ02_MSG_CODE_X  + ', '
    from CSPGJ02_MSG_OBJ J02
    where A04.SPGJ02_MSG_K = J02.SPGJ02_MSG_K  
    FOR XML PATH('')
) J02 (comments)
WHERE D30.SPGA02_BUSINESS_TYPE_C = 'serv'  
    AND D30.SPGA03_REGION_C = 'ap'  
    AND D30.SPGD30_SHIP_SITE_C = '0134a'  
ORDER BY D30.SPGD30_SHIP_SITE_C ASC, D30.SPGD30_RATING_MONTH_Y DESC, D30.SPGD30_LAST_TOUCH_Y DESC;

Note: You will notice that I changed your query to use JOIN syntax instead of the comma separated tables with the joins in the WHERE clause. This is standard ANSI syntax.

Answer 2

Using XML PATH('')

SELECT 
    D30.SPGD30_SHIP_SITE_C AS SHIPSITE,  
    D30.SPGD30_RATING_MONTH_Y AS RATINGMONTH,  
    D30.SPGD30_PRIOR_SCORE_R AS PRIOR, 
    D30.SPGD30_REVISED_SCORE_R AS REVISED,  
    CASE WHEN (CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 ) THEN CONVERT( VARCHAR(8), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X AS DATETIME) , 1) ELSE D30.SPGD30_TRACKED_ADJUSTMENT_X END ADJUSTMENTS,  
    STUFF(JO2.COMMENTS, 1, 1, '') AS COMMENTS,  
    D30.SPGD30_LAST_TOUCH_Y AS LASTUPDATED,  
    D30.SPGD30_LAST_TOUCH_C AS LASTUPDATEDCDSID   
FROM  
    CSPGD30_TRACKING D30 
CROSS JOIN CSPGD31_TRACKING_RATING_ELEMNT D31
CROSS JOIN CSPGA04_RATING_ELEMENT_MSTR A04
CROSS APPLY (
    SELECT
        ',' + ISNULL(JO2.SPGJ02_MSG_CODE_X, '')
    FROM CSPGJ02_MSG_OBJ JO2  
    WHERE A04.SPGJ02_MSG_K = JO2.SPGJ02_MSG_K  
    FOR XML PATH('')
) AS JO2 (COMMENTS)
WHERE  
    D30.SPGA02_BUSINESS_TYPE_C = D31.SPGA02_BUSINESS_TYPE_C  
AND 
    D30.SPGA03_REGION_C = D31.SPGA03_REGION_C  
AND 
    D30.SPGD30_SHIP_SITE_C = D31.SPGD30_SHIP_SITE_C  
AND 
    D30.SPGD30_RATING_MONTH_Y = D31.SPGD30_RATING_MONTH_Y  
AND 
    D30.SPGD30_TRACKED_ADJUSTMENT_X = D31.SPGD30_TRACKED_ADJUSTMENT_X  
AND 
    D30.SPGD30_LAST_TOUCH_Y = D31.SPGD30_LAST_TOUCH_Y  
AND 
    D31.SPGA04_RATING_ELEMENT_D = A04.SPGA04_RATING_ELEMENT_D  
AND 
    D30.SPGA02_BUSINESS_TYPE_C = 'serv'  
AND 
    D30.SPGA03_REGION_C = 'ap'  
AND 
    D30.SPGD30_SHIP_SITE_C = '0134a'  
ORDER BY   
    D30.SPGD30_SHIP_SITE_C ASC  ,
    D30.SPGD30_RATING_MONTH_Y DESC  ,
    D30.SPGD30_LAST_TOUCH_Y DESC 

This one will make a comma separated list of comments.

If you want to display multiple columns in one, you can write like this:

SELECT CAST([MyIntegerId] AS varchar(10)) + ' - ' + [Column1]+ ' - ' +CAST([MyDateTimeColumn] AS varchar(10)) + ' - ' + [Column2] AS 'My Merged Column'
FROM Mytable
