Question

我得到了一个oracle sql查询，它在oracle sql开发人员上运行正常，但是当我从Java编写的语句中运行它时，sql异常被抛出为“ORA-00942：表或视图不存在”并且用户获得了所有提到的权限3个架构。查询有什么问题吗？目前我似乎无法找到问题，仍然调试sql字符串也可以在SQL开发人员中执行。

SQL查询

SELECT CLI_CLIENT.NAME ,CLI_CLIENT.CLIENT_ID,

AA.SEARCHES,

(SELECT COUNT(*) FROM RES_BOOKING,CLI_WEB_USER WHERE  RES_BOOKING.BOOKED_USER=CLI_WEB_USER.ADM_USER_ID

AND TRUNC(RES_BOOKING.BOOKING_DATE) BETWEEN '01-MAR-16' AND '24-MAR-16' AND CLI_WEB_USER.CLIENT_ID=CLI_CLIENT.CLIENT_ID)AS BOOKINGS

FROM CLI_CLIENT,

(SELECT CWU.CLIENT_ID,

COUNT(ST.OPERATION) AS SEARCHES 

FROM STAT.ST_TRANSACTION ST , CLI_WEB_USER CWU , CACHE.CACC_CRITERIA CC , CACHE.CACC_CRITERIA_STATS CS

 WHERE ST.USER_NAME=CWU.USERNAME

 AND ST.OPERATION LIKE 'OTA_HotelAvailRQ%'

 AND TRUNC(ST.TRS_TIMESTAMP) BETWEEN '01-MAR-16' AND '24-MAR-16'

AND CWU.CLIENT_ID IN (10975,10040)

AND CC.CRITERIA_ID=CS.CRITERIA_ID

AND CS.SESSION_ID=ST.SESSION_ID

AND CS.DISTRIBUTION_CHANNEL='W'

 GROUP BY CLIENT_ID, CWU.CLIENT_ID

)AA

WHERE CLI_CLIENT.CLIENT_ID=AA.CLIENT_ID;

Java异常

 java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist

Answer 1

检查您是否在SQL Developer和Java应用程序中的同一用户帐户下连接到数据库。很可能情况并非如此，您的Java应用程序无法访问查询中的一个或多个表。

Answer 2

以下是您在更好的视图和效果中的查询：

select C.NAME,
       C.CLIENT_ID,
       AA.SEARCHES,
       (select count(1) 
          from RES_BOOKING R
          join CLI_WEB_USER U
            on U.ADM_USER_ID = R.BOOKED_USER
           and trunc(R.BOOKING_DATE) 
                between '01-MAR-16' 
                    and '24-MAR-16' 
           and U.CLIENT_ID = C.CLIENT_ID
        ) AS BOOKINGS
  from CLI_CLIENT C
  join 
       (select CWU.CLIENT_ID as CLIENT, 
               count(ST.OPERATION) AS SEARCHES 
          from STAT.ST_TRANSACTION ST 
          join CLI_WEB_USER CWU
            on CWU.USERNAME = ST.USER_NAME
          join CACHE.CACC_CRITERIA CC
            on CC.CRITERIA_ID = CS.CRITERIA_ID
          join CACHE.CACC_CRITERIA_STATS CS
            on CS.SESSION_ID = ST.SESSION_ID
         where ST.OPERATION like 'OTA_HotelAvailRQ%'
           and trunc(ST.TRS_TIMESTAMP) 
                between '01-MAR-16' 
                    and '24-MAR-16'
           and CWU.CLIENT_ID in (10975,10040)
           and CS.DISTRIBUTION_CHANNEL='W'
      group by CLIENT_ID, CLIENT -- OLD OF CLIENT -> CWU.CLIENT_ID
        ) AA
    on AA.CLIENT = C.CLIENT_ID; -- OLD OF AA.CLIENT -> AA.CLIENT_ID

然后将查询分成块并逐个执行。例如，

第一部分：

select C.NAME,
       C.CLIENT_ID,
       (select count(1) 
          from RES_BOOKING R
          join CLI_WEB_USER U
            on U.ADM_USER_ID = R.BOOKED_USER
           and trunc(R.BOOKING_DATE) 
                between '01-MAR-16' 
                    and '24-MAR-16' 
           and U.CLIENT_ID = C.CLIENT_ID
        ) AS BOOKINGS
  from CLI_CLIENT C;

第二部分：取JOIN块内的代码，依此类推。如果您在该区块中出现错误，请再划分并继续此操作。
