Sql 我想在select查询中使用totalmon和totalcost，而不是select查询*

我想在select查询中使用totalmon和totalcost，而不是select查询*

    SELECT *
    FROM (  SELECT
             SUM(il.linecost) AS totalcost
            ,DATENAME(m,il.actualdate) AS totalmon 
            FROM invuseline il
            LEFT JOIN glcomponents g ON g.compvalue = il.gldebitacct
            INNER JOIN invuse i ON i.invusenum = il.invusenum AND i.siteid = il.siteid
            INNER JOIN workorder w ON w.wonum = il.refwo and w.siteid = il.siteid
            WHERE (CONVERT(VARCHAR(10),il.actualdate,120) BETWEEN '2019-05-01' AND '2020-01-31')
            AND il.usetype = 'ISSUE'
            AND i.status = 'COMPLETE'
            GROUP BY DATENAME(m,il.actualdate)
        ) AS t

    PIVOT(  SUM(t.totalcost)
            FOR t.totalmon IN ( [January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December])
        ) AS pivot_table 

消息207，第16级，状态1，第13行无效列名“totalcost”

无法选择

totalcost

，因为它是列值

您应该学会设置查询格式。即使有jarlh的编辑，这仍然是不明白的我想帮助，但我甚至不能阅读这个查询。请把它编辑成易读的格式
