一列数据分成多列答案

【问题标题】：One column data into multiple column一列数据分成多列
【发布时间】：2020-01-20 08:48:48
【问题描述】：

我正在使用 SQL Server，我想根据每一列中的posid 数据这里是我的代码：

select ItcodedGrp,ItheadCat, ItheadCls,ItheadGrp,POsid,
(sum(OpnQty) + sum(FaultyQty) + sum(UsedQty) +  sum(RecQty) - sum(RejectQty)  - sum(Issued) + 
sum(DebitQty) + sum(AdjQty) + sum(STNQtyPls) - sum(STNQtyMin) - sum(POSQTY) - sum(TransitQty) - sum(FQtyMin)
+ sum(FQtyPlus) + sum(ReplaceQty)) as AllStock
from Vmgt_RSales_Stock
where POsid in   (2,6,7,10,11,12,13,14) and ItcodedGrp  like '28.01.059.%'
group by ItcodedGrp,ItheadCat, ItheadCls,ItheadGrp,POsid 
order by POsid asc

这是我的结果。

我要每栏按照posid的股票

如您在上图中所见，我的股票显示在 posid 前面，但我想要列中的所有股票，但 posid 明智的做法是让我举个例子，我的结果应该如下所示

【解决方案1】：

您可以使用条件聚合。您的 sum() 表达式很长，所以我会添加一级聚合以避免重复多次：

select
    ItcodedGrp,
    ItheadCat, 
    ItheadCls,
    ItheadGrp,
    sum(AllStock) AllStock,
    sum(case when POSid = 2  then AllStock end) POSid2,
    sum(case when POSid = 6  then AllStock end) POSid6,
    sum(case when POSid = 7  then AllStock end) POSid7,
    sum(case when POSid = 10 then AllStock end) POSid10,
    sum(case when POSid = 11 then AllStock end) POSid11,
    sum(case when POSid = 12 then AllStock end) POSid12,
    sum(case when POSid = 13 then AllStock end) POSid13,
    sum(case when POSid = 14 then AllStock end) POSid14
from (
    select 
        ItcodedGrp,
        ItheadCat, 
        ItheadCls,
        ItheadGrp,
        POsid,
        (
            sum(OpnQty) 
            + sum(FaultyQty) 
            + sum(UsedQty) 
            +  sum(RecQty) 
            - sum(RejectQty)  
            - sum(Issued) 
            + sum(DebitQty) 
            + sum(AdjQty) 
            + sum(STNQtyPls) 
            - sum(STNQtyMin) 
            - sum(POSQTY) 
            - sum(TransitQty) 
            - sum(FQtyMin)
            + sum(FQtyPlus) 
            + sum(ReplaceQty)
        ) as AllStock
    from Vmgt_RSales_Stock
    where 
        POsid in (2,6,7,10,11,12,13,14) 
        and ItcodedGrp  like '28.01.059.%'
    group by 
        ItcodedGrp,
        ItheadCat, 
        ItheadCls,
        ItheadGrp,
        POsid 
    ) t
group by 
    tcodedGrp,
    ItheadCat, 
    ItheadCls,
    ItheadGrp
