摘要:
Techniques are disclosed for reorganizing rows of a database table. In one embodiment, each row is associated with a respective row identifier. A mapping is provided that assigns a logical identifier to each row identifier. Each database index on the database table is configured to use the logical identifier rather than the row identifier. Accordingly, the rows of the database table may be reorganized without having to modify any database index on the database table.
