我在关联Oracle 8i上的子查询时遇到问题
该子查询给我一个ORA-00904:无效的列名,我不明白为什么。不行吗?
SELECT
HIST_FA.HIFA_PLAN_CODIGO AS FE_CODIGO_PLANTEL,
HIST_FA.HIFA_NUMERO AS FE_NUMERO_CONTROL,
HIST_FA.HIFA_FECHA AS FE_FECHA_HORA_EMISION,
HIST_FA.HIFA_DEST_CLIE_CODIGO AS FE_CODIGO_CLIENTE,
-- . . . a bunch of other columns . . .
FROM
VFA_HIST_FA HIST_FA,
VFA_HIST_ITEMS_FA HIST_ITEMS_FA,
(
SELECT
HIRF_HIIF_HIFA_NUMERO AS FE_NUMERO_CONTROL,
SUM(DECODE(HIRF_RETE_CODIGO, 0, HIRF_MONTO)) AS FE_MONTO_ENTREGADO,
SUM(DECODE(HIRF_RETE_CODIGO, 5, HIRF_MONTO)) AS FE_IMPUESTO_UNICO,
SUM(DECODE(HIRF_RETE_CODIGO, 6, HIRF_MONTO)) AS FE_MARGEN_COMERCIALIZACION
FROM
VFA_HIST_ITEMS_RETENC_FA
WHERE
HIRF_HIIF_HIFA_NUMERO = HIST_FA.HIFA_NUMERO
GROUP BY
HIRF_HIIF_HIFA_NUMERO
) PP
WHERE
HIST_FA.HIFA_NUMERO = HIST_ITEMS_FA.HIIF_HIFA_NUMERO;
当然,我可以在主WHERE
上执行此操作,但是它将扫描内部行中的所有行。
HIST_FA.HIFA_NUMERO = PP.FE_NUMERO_CONTROL
因此,这不是一种选择,因为查询将变得持久。
最诚挚的问候!

更改列名的别名 HIRF_HIIF_HIFA_NUMERO AS FE_NUMERO_CONTROL 改成其他名称,然后重试。
