Oracle SQL Developer - Error: “FROM keyword not found where expected”

问题

Sorry for my noob question but I'm trying to figure out why my Oracle-SQL indicates the error
"FROM keyword not found where expected" as the picture below:

The code I'm trying to run is the following:

select  
   PCKCOO AS 'COMPANHIA_DO_PEDIDO_NUMERO_DO_PEDIDO',
   PCDOCO AS 'DOCUMENTO_NUMERO_DA_OS_FATURA',
   PCDCTO AS 'TIPO_DE_ORDEM',
   PCSFXO AS 'SUFIXO_DO_PEDIDO',
   rpad(HORDT,'0',6) AS 'HORARIO_DE_LIBERACAO',
   FX_PARA_GREGORIANA(HORDJ, 'DD/MM/YYYY')||' '||rpad(HORDT,6,'0') "APROVACAO",
   rank() over (partition by pckcoo, pcdoco, pcdcto, pclnid order by FX_PARA_GREGORIANA(HORDJ, 'DD/MM/YYYY')||' '||rpad(HORDT,6,'0') desc) as rank,
   FROM PRODDTA.F5543170 a,
        proddta.f4209 b,
        proddta.f4301 c,  
   WHERE 
   PCKCOO = '52171' AND
   PCDCTO In ('OP','C1','C2','FZ','OF') AND
                   ((PCTRDJ >= '117060' AND PCTRDJ <= '117090') 
                   or (PCTRDJ >= '116061' AND PCTRDJ <= '116091')
                    ) and
                    ( b.hokcoo = a.pckcoo  and
                      b.hodoco = a.pcdoco and
                      b.hodcto = a.pcdcto and
                      B.HOASTS = '2A') and
                      (c.phkcoo (+)= a.pckcoo and
                       c.phdoco (+)= COALESCE(TO_NUMBER(REGEXP_SUBSTR(PCOORN, '^(-|+)?d+(.|,)?(d+)?$')), 0)  AND
                       c.phdcto (+)= 'OR')

The code was a lot bigger but I cut it into pieces in order to find out why this is happening (specially regarding the Line: 3 and Column: 25 as the error message indicated, which for me makes no sense).

Additionally, when I erase some lines in order to get closer towards the error, the red line (as indicated in the picture) keeps in the first line.

Do you have a guess of why this is happening? (sorry for the basic question again).

回答1:

You have a trailing comma in the last table (proddta.f4301 c) of FROM clause and should become

... 
FROM PRODDTA.F5543170 a,
     proddta.f4209 b,
     proddta.f4301 c  
...

which should be removed.

You also have a trailing comma in your select statement that should also be removed.

...
rank() over (partition by pckcoo, pcdoco, pcdcto, pclnid order by FX_PARA_GREGORIANA(HORDJ, 'DD/MM/YYYY')||' '||rpad(HORDT,6,'0') desc) as rank
...

Finally, for table alias you need to use double instead of single quotes:

select  
   PCKCOO AS "COMPANHIA_DO_PEDIDO_NUMERO_DO_PEDIDO",
   PCDOCO AS "DOCUMENTO_NUMERO_DA_OS_FATURA",
   PCDCTO AS "TIPO_DE_ORDEM",
   PCSFXO AS "SUFIXO_DO_PEDIDO",
   rpad(HORDT,'0',6) AS "HORARIO_DE_LIBERACAO",
...

回答2:

You have some trailing commas after AS RANK and after proddta.f4301 c.

Also, you can not use single quotes for column aliases, but you need double quotes; this should work:

SELECT PCKCOO AS "COMPANHIA_DO_PEDIDO_NUMERO_DO_PEDIDO",
       PCDOCO AS "DOCUMENTO_NUMERO_DA_OS_FATURA",
       PCDCTO AS "TIPO_DE_ORDEM",
       PCSFXO AS "SUFIXO_DO_PEDIDO",
       RPAD(
            HORDT,
            '0',
            6
           )
           AS "HORARIO_DE_LIBERACAO",
          FX_PARA_GREGORIANA(HORDJ, 'DD/MM/YYYY')
       || ' '
       || RPAD(
               HORDT,
               6,
               '0'
              )
           "APROVACAO",
       RANK()
           OVER(
                PARTITION BY pckcoo,
                             pcdoco,
                             pcdcto,
                             pclnid
                ORDER BY
                       FX_PARA_GREGORIANA(HORDJ, 'DD/MM/YYYY')
                    || ' '
                    || RPAD(
                            HORDT,
                            6,
                            '0'
                           ) DESC
               )
           AS RANK
  FROM PRODDTA.F5543170 a,
       proddta.f4209 b,
       proddta.f4301 c
 WHERE     PCKCOO = '52171'
       AND PCDCTO IN ('OP',
                      'C1',
                      'C2',
                      'FZ',
                      'OF')
       AND (   (    PCTRDJ >= '117060'
                AND PCTRDJ <= '117090')
            OR (    PCTRDJ >= '116061'
                AND PCTRDJ <= '116091'))
       AND (    b.hokcoo = a.pckcoo
            AND b.hodoco = a.pcdoco
            AND b.hodcto = a.pcdcto
            AND B.HOASTS = '2A')
       AND (    c.phkcoo(+) = a.pckcoo
            AND c.phdoco(+) = COALESCE(TO_NUMBER(REGEXP_SUBSTR(PCOORN, '^(-|+)?d+(.|,)?(d+)?$')), 0)
            AND c.phdcto(+) = 'OR')

As an aside, you should better switch to ANSI JOIN syntax.
