Answer 1

böyle Deneyin:

CREATE TABLE #test(id INT,value VARCHAR(100),condition INT); 
INSERT INTO #test VALUES 
(1,'value1',0) 
,(2,'value2',0) 
,(3,'value3',1) 
,(4,'value4',1); 

WITH MyDistinctConditions AS 
(
    SELECT DISTINCT condition 
    FROM #test 
) 
SELECT c.condition 
     ,(SELECT STUFF(
         (
         SELECT ', ' + CAST(t.id AS VARCHAR(10)) 
         FROM #test AS t 
         WHERE t.condition=c.condition 
         FOR XML PATH('')),1,2,'')) AS ids 
     ,(SELECT STUFF(
         (
         SELECT ', ' + t.value 
         FROM #test AS t 
         WHERE t.condition=c.condition 
         FOR XML PATH('')),1,2,'')) AS [values] 
FROM MyDistinctConditions AS c; 

DROP TABLE #test; 

sonucu

condition ids  values 
0   1, 2 value1, value2 
1   3, 4 value3, value4
