Question

我有一个问题：

WITH abc AS
(

   (SELECT SRC_DATA.*,
     (SELECT MAX(DECODE(OBJ.AUD_ACTION_FLAG,'D',OBJ.OUPDATE_COUNT,OBJ.NUPDATE_COUNT))
    FROM SMARTTRIAL_ODR_LANDING.AUD_TRIAL_DESIGN OBJ
    WHERE OBJ.AUD_DATE_CHANGED BETWEEN TO_DATE('01-JAN-1900') AND (SRC_DATA.AUD_DATE_CHANGED)
    AND DECODE(OBJ.AUD_ACTION_FLAG,'D',OBJ.OTRIAL_NO,OBJ.NTRIAL_NO)= DECODE(SRC_DATA.AUD_ACTION_FLAG,'D',SRC_DATA.OTRIAL_NO,SRC_DATA.NTRIAL_NO)
    AND OBJ.AUD_ACTION_FLAG <> 'D'
    ) UPDATE_COUNT,

 /***Multiple select statement like above with many other look up tables like  AUD_TRIAL_DESIGN ****/

FROM SMARTTRIAL_ODR_LANDING.AUD_TRIAL SRC_DATA  /***AUD_TRIAL  is the base table***/
),    


WITH def AS
(SELECT OBJ_DATA .*,
/***Similar statement as mentioned in above block and lookup table is AUD_OBJECTIVE***/

FROM SMARTTRIAL_ODR_LANDING.AUD_TRIAL_OBJECTIVE OBJ_DATA /***AUD_TRIAL_OBJECTIVE is the base table***/
)

----查询选择列-----

FROM abc
LEFT JOIN def
LEFT JOIN xyz ON (column from def = column from xyz)

对于我编写的查询的simliar结构，返回以下错误：

ORA-01792: maximum number of columns in a table or view is 1000
01792. 00000 -  "maximum number of columns in a table or view is 1000"
*Cause:    An attempt was made to create a table or view with more than 1000
           columns, or to add more columns to a table or view which pushes
           it over the maximum allowable limit of 1000. Note that unused
           columns in the table are counted toward the 1000 column limit.
*Action:   If the error is a result of a CREATE command, then reduce the
           number of columns in the command and resubmit. If the error is
           a result of an ALTER TABLE command, then there are two options:
           1) If the table contained unused columns, remove them by executing
           ALTER TABLE DROP UNUSED COLUMNS before adding new columns;
           2) Reduce the number of columns in the command and resubmit.

任何人都可以建议一个解决方案

我们遇到了类似的问题（以下是SR的摘录）：

创建视图生成ORA-01792表或视图中的最大列数为1000

我们有一个新的应用程序，其视图包含35列。但是，在创建它时，它会错误地指出有超过1000列，这是错误的。我将附上视图定义

这就是Oracle所说的（它确实解决了这个问题）：

这可能与您遇到的问题相同。
