为什么这个查询

SELECT p.name AS design,
  p.M_PRODUCT_CATEGORY_ID,
  il.PRICEACTUAL   AS price,
  bp.C_BPARTNER_ID AS idpartner,
  CASE
    WHEN i.IsReturnTrx = 'N'
    THEN SUM(il.linenetamt)
    ELSE SUM(il.linenetamt)*-1
  END AS netHT,
  CASE
    WHEN i.IsReturnTrx = 'N'
    THEN SUM((il.linenetamt + (il.linenetamt * t.rate /100)))
    ELSE SUM((il.linenetamt + (il.linenetamt * t.rate /100)))*-1
  END AS netTTC,
  (SELECT il.qtyinvoiced
  FROM C_InvoiceLine il

  )              AS qtydepot,
  (SELECT qtyinvoiced

ORDER BY p.name ,

给我这个错误：

Answer 1

除了order by子句外，您不能在同一级别的SQL中引用列别名。

From the documentation（强调补充）：

您可以使用列别名 c_alias 来标记选择列表中前一个表达式，以便使用新标题显示该列。别名在查询期间有效地重命名选择列表项。 别名可用于ORDER BY子句，但不能用于查询中的其他子句。

当您在QTYLIV cluase中引用GROUP BY时，尚未对选择列表进行评估且别名不存在。这就是解析和执行查询的方式。

当您在选择列表中有复杂的表达式时，通常最简单的方法是将其包装在外部选择中并在之后进行分组：

SELECT *
FROM (
  SELECT p.name AS design,
    p.M_PRODUCT_CATEGORY_ID,
    il.PRICEACTUAL   AS price,
    bp.C_BPARTNER_ID AS idpartner,
    CASE
  ...
    (SELECT qtyinvoiced
    FROM C_InvoiceLine il
    WHERE bp.ISCUSTOMER ='Y'
    AND bp.C_BPARTNER_ID= 18888
    )               AS qtyliv,
  ...
    i.DATEINVOICED AS dat
  FROM C_InvoiceLine il
  INNER JOIN M_PRODUCT p
  ...
  ON (oi.c_location_id=loc2.c_location_id)
    --WHERE i.DateInvoiced BETWEEN $P{Date1} AND $P{Date2}
    --AND
    --i.DocStatus in ('CO','CL')
    --AND i.IsSoTrx = 'Y'
    --AND   p.isstocked='Y'
)
GROUP BY name ,
  M_PRODUCT_CATEGORY_ID,
  QTYINVOICED,
  PRICEACTUAL,
...
  qtyliv,
  qtydepot
ORDER BY name ,
  dateinvoiced ;

请注意，您不会在外部选择中的GROUP BY或ORDER BY子句中使用原始表别名，因为这些不在范围内。

Answer 2

问题是（至少）在group by子句中。 Oracle不允许group by中的列别名。您可以使用子查询轻松解决此问题：

select t.*
from (select . . .
      from . . .
      where . . .
     ) t
group by . . . 
order by . . . ;

换句话说，将group by和order by之外的所有内容放在子查询中。然后将这些子句放在外部查询中。

ORA-00904 group by子句中标识符的“无效标识符”
