SQLServer行转列实现思路记录

DECLARE @s NVARCHAR(4000)
SELECT @s = ISNULL(@s + ',', '') + QUOTENAME(ScoreName)
FROM (select distinct ScoreName from Score) as A ---列名不要重复

Declare @sql NVARCHAR(4000)
SET @sql='
select r.* from
(select UID,Name,ScoreName,Score from Score,[User] where Score.UID=[User].ID) as t
pivot
(
max(t.Score)
for t.ScoreName in ('+@s+')
) as r'
EXEC( @sql)
