創建OrderInfo 表

CREATE TABLE OrderInfo 
(
    OrderGuid uniqueidentifier not null,
    LoginId varchar(50) not null,
)

創建OrderProduct表

CREATE TABLE OrderProduct
(
    ProductGuid uniqueidentifier not null,
    ProductName varchar(100) not null,
    OrderGuid uniqueidentifier not null,
)

向OrderInfo 表插入數據

insert into OrderInfo(OrderGuid,LoginId)values(NEWID(),'15678975078')
insert into OrderInfo(OrderGuid,LoginId)values(NEWID(),'15678971111')
insert into OrderInfo(OrderGuid,LoginId)values(NEWID(),'15678971111')
insert into OrderInfo(OrderGuid,LoginId)values(NEWID(),'15678971111')
insert into OrderInfo(OrderGuid,LoginId)values(NEWID(),'15678971111')
insert into OrderInfo(OrderGuid,LoginId)values(NEWID(),'15678971111')
insert into OrderInfo(OrderGuid,LoginId)values(NEWID(),'15678973333')

select * from OrderInfo

向OrderProduct表插入數據

同一張表數據的拼接

SELECT  p2.LoginId, OrderGuid = STUFF((
            SELECT ',' + convert(varchar(36),OrderGuid)
            FROM OrderInfo AS p1
            WHERE p1.LoginId = p2.LoginId
            FOR XML PATH('')
            ), 1, 1, '') FROM OrderInfo AS p2
GROUP BY p2.LoginId

SELECT  p2.OrderGuid, ProductName = STUFF((
            SELECT ',' + ProductName
            FROM OrderProduct AS p1
            WHERE p1.OrderGuid = p2.OrderGuid
            FOR XML PATH('')
            ), 1, 1, '') FROM OrderProduct AS p2
GROUP BY p2.OrderGuid

不同表數據的拼接

SELECT  p2.OrderGuid,p2.LoginId, ProductName = STUFF((
            SELECT ',' + ProductName
            FROM OrderProduct AS p1
            WHERE p1.OrderGuid = p2.OrderGuid
            FOR XML PATH('')
            ), 1, 1, '') FROM OrderInfo AS p2
GROUP BY p2.OrderGuid,p2.LoginId
