使用“create as”语句创建索引组织表的 Oracle 问题

Question

So I'm trying to create a copy of one of my tables into an index organized table, However I get an error, here is the code.

create table clients2 as
select *
from clients
organization index;

ORA-00933:"SQL command not properly ended"

Answer 1

Your command is wrong.

SQL> create table testiot ( object_id primary key,object_name ) 
     organization index 
     as select object_id,object_name from dba_objects 
     where object_id is not null ;

Table created.

SQL> select count(*) from testiot ;

  COUNT(*)
----------
    208730

Organization index must be in the definition of the table and before as select . On the other hand, you need to define the columns in the table and which one is the primary key for IOT.
