Invalid identifier error when using RIGHT JOIN inside FROM clause - sql

Question

I want to use within a FROM a subset of 2 tables using RIGHT JOIN (I want from that subset all the rows of ITV2_VEHICULOS whose ID is not in ITV2_HIST_VEHICULOS) so that the SELECT "takes" the data from there and with the WHERE it can filter
My query:
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...
I expect in the output:
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)

This is what your query would look like if you use "explicit join syntax" instead of just some commas between table names:
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
Now I had to pull out several tables and the subquery from that because, frankly, they don't make much sense to me:
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
