Question

拥有如下所示的数据

ItemCode    SalesPrice  PricingLevel
ITEM-000001 451.000000  Barons
ITEM-000001 432.000000  Guild

是否有办法获得以下输出：

ItemCode      Barons     Guild
ITEM-000001   451        432

Answer 1

SELECT ItemCode, 
Sum(Case when PricingLevel = 'Barons' Then SalesPrice else 0 end) as Barons,
Sum(Case when PricingLevel = 'Guild' Then SalesPrice else 0 end) as Guild
FROM myTable
GROUP BY ItemCode

Answer 2

试试这个（注意：因为我不知道你的表名，我称之为“项目”）：

SELECT DISTINCT I1.ItemCode, 
       (SELECT SalesPrice FROM Items I2 WHERE I2.ItemCode = I1.ItemCode AND I2.PricingLevel = 'Barons') Barons,
       (SELECT SalesPrice FROM Items I3 WHERE I3.ItemCode = I1.ItemCode AND I3.PricingLevel = 'Guild') Guild
FROM Items I1

如果不显示小数零，请使用以下命令：

SELECT DISTINCT I1.ItemCode, 
       (SELECT CAST(SalesPrice AS DECIMAL(10,0)) FROM Items I2 WHERE I2.ItemCode = I1.ItemCode AND I2.PricingLevel = 'Barons') Barons,
       (SELECT CAST(SalesPrice AS DECIMAL(10,0)) FROM Items I3 WHERE I3.ItemCode = I1.ItemCode AND I3.PricingLevel = 'Guild') Guild
FROM Items I1

获取格式化的输出
