Hi,

Can any one tell me the reason behind the below statements:

1) We cant create TABLE PARTITIONED on CLUSTER or INDEX on CLUSTER TABLE.

2) We cant create a partitioned table with the column of LONG or LONGRAW? (But how it could be possible with BLOB, CLOB?


Thanks in advance.

1a) It irrelevant as this is the cluster that determines the table implementation/organization not the table itself.

1b) You can
SQL> create cluster c (col integer) ;

Cluster created.

SQL> create table t (col integer, col2 integer) cluster c (col);

Table created.

SQL> create index i on t (col2);

Index created.

2) LONG and LONG RAW are obsolete, why Oracle would take care of something obsolete?

Regards
Michel

With regard to your first question, a very similar effect to partitioning a cluster would be to use reference partitioning (though you can't do that until you upgrade to 11g, could this be the driver that finally makes you do this?)
