SQL將一列轉換成一行，並將這一行形成新的列

sql部分-----

.查詢出來要轉換的資料

select name from dbo.base_pay_type where is_enabled = 1

資料如圖：

select stuff((select  '

[' + name + '],'
from(select name from dbo.base_pay_type where is_enabled = 1) a for xml path('') ), 1,0, '') as name 
如圖：

select left(a.name,len(a.name)-1) as name from (select stuff((select  '

[' + name + '],'
from(select name from dbo.base_pay_type where is_enabled = 1) a for xml path('') ), 1,0, '') as name ) as a
如圖：

select *from (

select sellerid,pay_type_name,cast(sum(amount) as
decimal(18,2)) as payamout from
( select distinct oi.order_guid,ss.sellerid,bs.name as pay_type_name,op.amount
from dbo.shop_sellers as ss
left join dbo.order_item oi on ss.sellerid=oi.tracking_id
left join dbo.order_list ol on ol.order_guid =oi.order_guid
left join dbo.order_pay op on ol.order_guid=op.order_guid
left join dbo.base_pay_type bs on op.pay_type_id=bs.pay_type_id
inner join dbo.shops s on s.shopguid=ol.owner
where bs.is_enabled=1 and op.is_received=1 and order_status='
finished
' and pay_status='
paid
'and s.shopid in(select shopid from dbo.shops where 
1=1 and shopid=15 or parentshopid=15
) and ol.order_time between 
'2018-01-17
' and '
2018-08-17 23:59:59
') a
group by sellerid,pay_type_name) as pa pivot(max( payamout ) for

string sql = "

select left(a.name,len(a.name)-1) as name from (select stuff((select '[' + name + '],' 
from(select name from dbo.base_pay_type where is_enabled = 1) a for xml path('') ), 1, 0, '') as name ) as a";
datatable dt =dbaccess.executetable(sql);
string filwes = dt.rows[0]["
name
"].tostring();
得到的結果如上面標題3,然後拼接sql,將filwes作為引數輸入下面sql語句

select sellerid,pay_type_name,cast(sum(amount) as decimal(18,2)) as payamout from (

select distinct oi.order_guid,ss.sellerid,bs.name as pay_type_name,op.amount

from dbo.shop_sellers as ss

left join dbo.order_item oi on ss.sellerid=oi.tracking_id

left join dbo.order_list ol on ol.order_guid = oi.order_guid

left join dbo.order_pay op on ol.order_guid=op.order_guid

left join dbo.base_pay_type bs on op.pay_type_id=bs.pay_type_id

inner join dbo.shops s on s.shopguid=ol.owner

where bs.is_enabled=1 and op.is_received=1 and order_status='finished' and pay_status='paid'

and s.shopid in(select shopid from dbo.shops where 1=1 ) ) a

group by sellerid,pay_type_name) as pa pivot(max( payamout ) for pay_type_name in (『「+filwes+」』))ppa
