R-Tree Indexing

Question

Hi.
Is it possible to direct in which tablespace the R-tree index table will go.
I know that you have a tablespace parameter in creating a quadtree index but I can't find one when creating the R-tree index.
I'm using Oracle 8.1.7

Answer 1

An index entry is created in the SYSTEM tablespace but the spatial indices are created in the tablespace you specify. To verify it execute the following:
select table_name,tablespace_name
from user_tables
where table_name like 'spatial_table%';
It will return your table_name plus the spatial index table created for it.
The table_name will look something like this:
spatial_table_SX_FL10$ for fixed quad tree and spatial_table_RT$ for rtree.
You can query the same for the indexes built on that previous table.
select index_name,tablespace_name
from user_indexes
where table_name = 'SPATIAL_TABLE_SX_FL10$';
The two index names would look like:
spatial_table_sx_fl10$B1
spatial_table_sx_fl10$B2
They should be created in the tablespace specified in the tablespace parameter when creating the spatial index.
Does that help any?
