What if I just not using any LOCAL or GLOBAL for creating index on a partitioned table like as I said:

create index xxxx on test1(col2) tablespace users; ------------as you see no LOCAL no GLOBAL is this wrong or NOT?

Hamid,

You ae referring to decision between two types of indexes in case of a partitioned table. You couls have a LOCAL index, in which case the index will partitioned exactly in the same way as the table. The other one is GLOBAL index, in which case you simple create an index (unpartitioned, if you wish) on the table. The global index may be partitioned but the partitioning scheme may not be even remotely close to that of the table. In case of a partitoned table, you have to use the keywords LOCAL or GLOBAL in index creation script to specify what it is.

Hope this helps.
