Question

我想在FROM中使用RIGHT JOIN使用2个表的子集（我希望ID不在ITV2_VEHICULOS中的ITV2_HIST_VEHICULOS的所有行），以便SELECT从那里“获取”数据，并使用WHERE进行过滤

我的查询：

SELECT
    *
FROM
    ITV2_INSPECCIONES I,
    ITV2_HORAS_INSPECCION HI_FIN,
    ITV2_INSPECCIONES I_SIG,
    ITV2_HORAS_INSPECCION HI_SIG_INI,
    ITV2_HIST_VEHICULOS VH,
    ITV2_CATEGORIAS_VEHICULO CAT,
    ITV2_CLASIF_VEH_CONS CVC,
    ITV2_CLASIF_VEH_USO CVU,
    (
        SELECT
            *
        FROM
            ITV2_HIST_VEHICULOS VH
        RIGHT JOIN ITV2_VEHICULOS V ON
            VH.C_VEHICULO_ID = V.C_VEHICULO_ID
    ) VI 

WHERE
    I.C_TIPO_INSPECCION = 1     
    AND I.F_DESFAVORABLE IS NOT NULL
    AND I.C_RESULTADO IN(
        3,
        4
    )
    AND I.C_VEHICULO_ID = VI.C_VEHICULO_ID 
    AND VI.C_CATEGORIA_ID = CAT.C_CATEGORIA_ID
    AND VI.C_CLASIF_VEH_CONS_ID = CVC.C_CLASIF_VEH_CONS_ID
    AND VI.C_CLASIF_VEH_USO_ID = CVU.C_CLASIF_VEH_USO_ID -- HORAS  
    AND I.C_ESTACION_ID = HI_FIN.C_ESTACION_ID
    AND I.C_INSPECCION_ID = HI_FIN.C_INSPECCION_ID
    AND I.N_ANNO = HI_FIN.N_ANNO
    AND HI_FIN.C_TIPO_HORA_ID = 6 -- INSPECCION SIGUIENTE   
    AND I.C_ESTACION_ID = I_SIG.C_ESTACION_ID_FASE_ANT
    AND I.C_INSPECCION_ID = I_SIG.C_INSPECCION_ID_FASE_ANT
    AND I.N_ANNO = I_SIG.N_ANNO_FASE_ANT --    
    AND I_SIG.N_ANNO IN(
        2013,
        2014,
        2015,
        2016,
        2017,
        2018
    )
    AND I_SIG.C_ESTACION_ID IN(
        3,
        21,
        22,
        26,
        28,
        32,
        34,
        37,
        41,
        47,
        53,
        59,
        60
    )
    AND I_SIG.F_INSPECCION >= '01/09/2015'
    AND I_SIG.F_INSPECCION <= '30/09/2018' --

    AND I_SIG.F_DESFAVORABLE IS NULL
    AND I_SIG.C_RESULTADO IN(
        1,
        2
    ) -- Y HORAS

    AND I_SIG.C_ESTACION_ID = HI_SIG_INI.C_ESTACION_ID
    AND I_SIG.C_INSPECCION_ID = HI_SIG_INI.C_INSPECCION_ID
    AND I_SIG.N_ANNO = HI_SIG_INI.N_ANNO
    AND HI_SIG_INI.C_TIPO_HORA_ID = 1

 --GROUP BY...

我希望在输出中：

C_ESTACION_ID(FROM I) |C_VEHICULO_ID(FROM(I) |C_TIPO_HORA_ID(FROM HI_FIN)|F_HORA (FROM I_FIN) |A_MATRICULA FROM (V) | F_CAMBIO FROM (VH -> IF subdata of V EXISTS)
 ---------------------|----------------------|---------------------------|--------------------|---------------------|---------------------------------------

如果使用“显式连接语法”而不是表名之间的逗号，这就是查询的样子：

SELECT *
FROM ITV2_INSPECCIONES I
INNER JOIN ITV2_HORAS_INSPECCION HI_FIN ON I.C_ESTACION_ID = HI_FIN.C_ESTACION_ID
     AND I.C_INSPECCION_ID = HI_FIN.C_INSPECCION_ID
     AND I.N_ANNO = HI_FIN.N_ANNO
INNER JOIN ITV2_INSPECCIONES I_SIG ON I.C_ESTACION_ID = I_SIG.C_ESTACION_ID_FASE_ANT
     AND I.C_INSPECCION_ID = I_SIG.C_INSPECCION_ID_FASE_ANT
     AND I.N_ANNO = I_SIG.N_ANNO_FASE_ANT
INNER JOIN ITV2_HORAS_INSPECCION HI_SIG_INI ON I_SIG.C_ESTACION_ID = HI_SIG_INI.C_ESTACION_ID
     AND I_SIG.C_INSPECCION_ID = HI_SIG_INI.C_INSPECCION_ID
     AND I_SIG.N_ANNO = HI_SIG_INI.N_ANNO
WHERE I.C_TIPO_INSPECCION = 1
    AND I.F_DESFAVORABLE IS NOT NULL
    AND I.C_RESULTADO IN (3, 4)
    AND HI_FIN.C_TIPO_HORA_ID = 6 -- INSPECCION SIGUIENTE   
    AND HI_SIG_INI.C_TIPO_HORA_ID = 1
    AND I_SIG.F_INSPECCION >= '01/09/2015'
    AND I_SIG.F_INSPECCION <= '30/09/2018'
    AND I_SIG.F_DESFAVORABLE IS NULL
    AND I_SIG.N_ANNO IN (2013, 2014, 2015, 2016, 2017, 2018)
    AND I_SIG.C_ESTACION_ID IN (3, 21, 22, 26, 28, 32, 34, 37, 41, 47, 53, 59, 60)
    AND I_SIG.C_RESULTADO IN (1, 2) -- Y HORAS

现在我不得不从中取出几个表和子查询，因为坦率地说，它们对我来说没有太大意义：

ITV2_HIST_VEHICULOS VH,         << no join conditions to preceding tables
ITV2_CATEGORIAS_VEHICULO CAT,   << no join conditions to preceding tables
ITV2_CLASIF_VEH_CONS CVC,       << no join conditions to preceding tables
ITV2_CLASIF_VEH_USO CVU,        << no join conditions to preceding tables
(
    SELECT
        *
    FROM ITV2_VEHICULOS V
    LEFT JOIN ITV2_HIST_VEHICULOS VH ON
        VH.C_VEHICULO_ID = V.C_VEHICULO_ID
) VI
AND I.C_VEHICULO_ID = VI.C_VEHICULO_ID 
AND VI.C_CATEGORIA_ID = CAT.C_CATEGORIA_ID
AND VI.C_CLASIF_VEH_CONS_ID = CVC.C_CLASIF_VEH_CONS_ID
AND VI.C_CLASIF_VEH_USO_ID = CVU.C_CLASIF_VEH_USO_ID

在FROM子句中使用RIGHT JOIN时出现无效的标识符错误
