Question

我使用的是动态SQL：

根据一天中的时间创建一个表和一些分区。

在Oracle 11g数据库上工作正常，但在Oracle 10g上我收到以下错误：

ORA-00923: FROM keyword not found where expected

尝试运行以下查询alene，也给我错误：

select listagg('PARTITION TABLE_NAME_' || to_char(sysdate + (level-1)/24, 'yyyymmddHH24') ||
' VALUES LESS THAN (TIMESTAMP''' || to_char(sysdate + (level)/24, 'yyyy-mm-dd HH24') || ':00:00''), ')
within group (order by level)
from dual
connect by level <= 24;

为什么会这样？

Answer 1

你可以尝试这样的事情。

   SELECT WMSYS.WM_CONCAT('PARTITION TABLE_NAME_'
  || TO_CHAR(sysdate + (level-1)/24, 'yyyymmddHH24')
  || ' VALUES LESS THAN (TIMESTAMP'''
  || TO_CHAR(sysdate + (level)/24, 'yyyy-mm-dd HH24')
  || ':00:00'') ') OUTPUT
FROM DUAL
  CONNECT BY level <= 24

“ORA-00923：FROM关键字未找到预期位置”仅适用于Oracle 10g而不是11g
