SQl 2008 合龙表字段

SQl 2008 合并表字段
问一下大虾，通过多表查询得出一下结果
ID NAME1 NAME2
---------- ---------- ----------
1 aa x1
1 bb x1
1 cc x1
2 mm y1
2 vv y1

我想要的结果：
ID NAME1 NAME2
---------- ---------- ----------
1 aa,bb,cc x1
2 mm,vv y1

SQL sever 语句怎么实现
[解决办法]
这个要写一个自定义函数来实现，sql无法实现。
[解决办法]
SELECT id,STUFF((SELECT ','+name FROM Test WHERE id=T.id FOR XML PATH('')),1,1,'') AS 别名 FROM Test T GROUP BY T.id

[解决办法]

你也可以一次先全部读到DataTable中，然后用函数或linq处理
[解决办法]

WITH tb(ID, NAME1, NAME2)
AS
(
    SELECT 1,'aa','x1'
   UNION ALL
    SELECT 1,'bb','x1'
   UNION ALL
    SELECT 1,'cc','x1'
   UNION ALL
    SELECT 2,'mm','y1'
   UNION ALL
    SELECT 2,'vv','y1'
)
 
SELECT id,
       name1 = STUFF((SELECT DISTINCT  ',' + name1 FROM   tb a WHERE  a.id = tb.id FOR XML PATH('')),1,1,''),
       name2 = STUFF((SELECT DISTINCT ',' + name2 FROM   tb a WHERE  a.id = tb.id FOR XML PATH('')),1,1,'')
FROM   tb
GROUP BY id;

[解决办法]

DECLARE Test_Cursor CURSOR FOR
SELECT ID,Name1,Name2 FROM Test1
DECLARE @ID INT
DECLARE @Name1 Nvarchar(50)
DECLARE @Name2 Nvarchar(50)
DECLARE @t TABLE(ID INT,Name1 Nvarchar(50),Name2 Nvarchar(50))--定义结果集表变量
OPEN Test_Cursor --打开游标
FETCH NEXT FROM Test_Cursor INTO @ID,@Name1,@Name2
DECLARE @tempID INT = 0
DECLARE @tempName1 varchar(50) =''
DECLARE @tempName2 varchar(50) =''
WHILE @@FETCH_STATUS = 0
BEGIN
IF(@tempID = 0)
BEGIN
SET @tempID = @ID
SET @tempName1 = @Name1
SET @tempName2 = @Name2
END
ELSE IF(@tempID = @ID)
BEGIN

SET @tempID = @ID
SET @tempName1 = @tempName1+',' + @Name1
SET @tempName2 = @Name2
SELECT @tempName1
END
ELSE
BEGIN
INSERT INTO @t (ID,Name1,Name2)SELECT @tempID,@tempName1,@tempName2
SET @tempID = @ID
SET @tempName1 = @Name1
SET @tempName2 = @Name2
INSERT INTO @t (ID,Name1,Name2)SELECT @tempID,@tempName1,@tempName2
END
FETCH NEXT FROM Test_Cursor INTO @ID,@Name1,@Name2
END
CLOSE Test_Cursor
DEALLOCATE Test_Cursor
SELECT * FROM @t

这个是游标做的技术不行还是有一点差距没时间帮你弄了要有事去了。如果下次来看没解决我就继续看
