我有这样的表
ID Status
1 5
1 6
1 7
2 5
2 6
2 7
我需要如下结果
ID col1 col2 col3
1 5 6 7
2 5 6 7
请帮帮我
解决方法
SELECT ID,MAX(CASE WHEN status = 5 THEN Status ELSE NULL END) col1,MAX(CASE WHEN status = 6 THEN Status ELSE NULL END) col2,MAX(CASE WHEN status = 7 THEN Status ELSE NULL END) col3 FROM tableNAME GROUP BY ID
使用PIVOT
SELECT *
FROM (
SELECT ID,Status,CASE Status
WHEN 5 THEN 'Col1'
WHEN 6 THEN 'Col2'
WHEN 7 THEN 'Col3'
END Stat
FROM tableName
) src
PIVOT
(
MAX(Status)
FOR Stat IN ([Col1],[Col2],[Col3])
) pivotTbl
