Oracle条件限制SQL查询

Question

我有此sql用于oracle数据库。 如何写条件以获取5到30之间的数据？ 基于sql的值，我想使用分页在php中创建一个datagrid。

"select c.case_id as NGM_ID,   
       s.NE_PRIORITAET as NE_PRIO,
       case substr(s.NE_ID, 2,1)
         when '0' then 'Zentrale'
         when '1' then 'Nord'
         when '2' then 'Nord' 
         when '3' then 'Ost'
         when '4' then 'Ost'

Answer 1

像这样：

select * from (
select ROW_NUMBER() OVER(order by c.CREATION_TIME desc) rn, c.case_id as NGM_ID,   
       s.NE_PRIORITAET as NE_PRIO,
       case substr(s.NE_ID, 2,1)
         when '0' then 'Zentrale'
         when '1' then 'Nord'
         when '2' then 'Nord' 
         when '3' then 'Ost'
         when '4' then 'Ost'
         when '5' then 'Mitte'
         when '6' then 'West'
         when '7' then 'Süd'
         when '8' then 'Mitte'
         when '9' then 'Süd'
         else          'Error'
       end as REGION,         
       c.STATUS_NGM as NGM_STATUS,
