ORA-00903 PHP Codeigniter中的表名无效

我在查询代码点火器中出错。这是错误

是不是因为在

JOIN

子句中，我将

MONTH

与

ID

进行比较？因为在我与

ID

比较的其他函数中，它工作得很好

编辑：我在下面发布详细查询

SELECT M.MONTH AS MONTH, O.ALL_OTHER AS ALL_OTHER
FROM (SELECT TO_DATE(TO_CHAR(SCHEDULED_DEPDT_LC, 'MON-YY'), 'MM-YY') AS MONTH
      FROM DBODSXML4OPS.XML4OPS
      WHERE STATUS IN ('Scheduled') and SERVICETYPE IN ('J','G') and TO_CHAR(SCHEDULED_DEPDT_LC, 'yyyy-mm-dd') BETWEEN '$datefrom' AND '$dateto'
      GROUP BY TO_DATE(TO_CHAR(SCHEDULED_DEPDT_LC, 'MON-YY'), 'MM-YY')
      ORDER BY MONTH) M
LEFT JOIN (SELECT TO_DATE(TO_CHAR(SCHEDULED_DEPDT_LC, 'MON-YY'), 'MM-YY') AS MONTH, COUNT(CASE WHEN DBODSXML4OPS.XML4OPS_DELAY.REASONCODE IN ('51','52','90','93','97','98','99') THEN 1 ELSE NULL END) AS ALL_OTHER
           FROM DBODSXML4OPS.XML4OPS
           JOIN DBODSXML4OPS.XML4OPS_DELAY on DBODSXML4OPS.XML4OPS.FLIGHTLEGREF = DBODSXML4OPS.XML4OPS_DELAY.FLIGHTLEGREF
           where STATUS IN ('Scheduled') and SERVICETYPE IN ('J','G') and TO_CHAR(SCHEDULED_DEPDT_LC, 'yyyy-mm-dd') BETWEEN '$datefrom' AND '$dateto'
           group by TO_DATE(TO_CHAR(SCHEDULED_DEPDT_LC, 'MON-YY'), 'MM-YY')
           order by MONTH) O ON M.MONTH = O.MONTH
ORDER BY M.MONTH DESC

FROM SELECT TO_DATE（TO_CHAR（SCHEDULED_DEPDT_LC，'MON-YY'），'MM-YY'）AS MONTH

此部分将取消您的查询。从选择中删除

，您应该会表现良好。如果您试图从第一个select中的另一个表中获取结果，请使用括号来分隔该表的相关部分query@aynber实际上，我已经在

子句的

后面写了括号。我已经在下面发布了详细信息查询。在上面发布的代码中，
FROM SELECT
应该是
FROM（SELECT
）。但我不确定下面的答案与此有何关系。@WilliamRobertson我已经编辑了我的问题。您的错误消息仍然显示无效代码（缺少括号）。您现在是否收到了其他错误？
