Question

我有一个要求，我已经为物化视图访问了ddl并执行它。我已为物化视图创建脚本，如下所示：

x*(b-k)+k*(x+1) = a
b*x - k*x + k*x + k = a
b*x + k = a

我尝试了以下替换语句，但它不起作用：

 CREATE MATERIALIZED VIEW "XXX"."AUD_MV_DCST" ("BUCKET", "ID", "SUM")
  ORGANIZATION HEAP PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 
 NOCOMPRESS LOGGING
  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
  TABLESPACE "USERS" 
  BUILD IMMEDIATE
  USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 
  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1
  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
  TABLESPACE "USERS" 
  REFRESH FAST ON COMMIT
  USING DEFAULT LOCAL ROLLBACK SEGMENT
  USING ENFORCED CONSTRAINTS ENABLE QUERY REWRITE
  AS SELECT TRUNC(STATUS_TIMESTAMP, 'HH24') BUCKET, ID, SUM(1) 
  .....

打破这个是什么

select replace(create_script, '''','''''') from dual

开合括号。我收到错误：

'HH24')

以下是执行此操作的存储过程：

ORA-00907: missing right parenthesis
ORA-06512: at "XXX.createProc", line 67
ORA-06512: at line 2

有关如何解决这个问题的任何建议？

我尝试了以下内容并且没有任何问题：

SQL> select trunc(current_timestamp, 'HH24') BUCKET from dual;

BUCKET
------------------
20-NOV-15

SQL>

尝试不使用精确说明符并使用：

SQL> select trunc(current_timestamp) BUCKET from dual;

BUCKET
------------------
20-NOV-15

SQL>
