查询可在 Oracle 11g 上运行，但在 Oracle 8i 上失败

Query works on Oracle 11g but fails on Oracle 8i(查询可在 Oracle 11g 上运行，但在 Oracle 8i 上失败)

问题描述

我在 Oracle 11g 中运行此查询没有问题:

I am running this query in Oracle 11g with no problem:

select (case
         when seqnum = 1 then
          '1'
         when seqnum = cnt then
          '0'
       end) as value1,
       (case
         when seqnum = 1 then
          t.BEGIN_DT
         when seqnum = cnt then
          t.END_DT
       end) as TIME1,      
       t4.UNIT1 || '.SUBBATCH_TRIGGER' TAG     
  from (select t.*,
               row_number() over(partition by t.BATCH_ID, t.plant_unit, t3.ID2 order by t.BEGIN_DT) as seqnum,
               count(*) over(partition by t.BATCH_ID, t.plant_unit, t3.ID2) as cnt
          from SCH2.tb_pg_unit_stap t
join (select ID1,batch_id from SCH2.VW_BATCH) t2 on t.BATCH_ID = t2.BATCH_ID
join (select ID2,ID1 from SCH1.STEP) t3 on t3.ID1 = t2.ID1) t
join SCH2.TB_W_MACHINE t4 on t4.plant_unit = t.plant_unit
where (seqnum = 1
    or seqnum = cnt) AND (t.BEGIN_DT > '01-jan-2013' AND t.BEGIN_DT < '01-feb-2013');

但是当我在 Oracle 8i (8.7.1) 中运行它时，它给出了 ORA-00933:SQL 命令没有正确结束.

But when I run it in Oracle 8i (8.7.1) it gives ORA-00933: SQL command not properly ended.

在 Oracle 8i 中运行 sql 命令有什么我必须知道的特殊注意事项吗?

Is there anys special consideration I must know for running sql commands in Oracle 8i?

提前致谢

推荐答案

AFAK case 命令从 9i 开始引入.

AFAK case command was introduced since 9i.
