Example

This operation can only be observed by using EXPLAIN PLAN to populate the plan table. It does not appear in AUTOTRACE or V$SQL_PLAN

This example was developed using Oracle 9.2.0.1 on Windows 2000

This example requires the following table definition

    CREATE TABLE t1 (c1 NUMBER,c2 NUMBER)
    PARTITION BY RANGE (c1)
    (
      PARTITION p1 VALUES LESS THAN (10),
      PARTITION p2 VALUES LESS THAN (20)
    );

The table does not need to be analysed

The statement

    EXPLAIN PLAN FOR
    CREATE INDEX i1 ON t1 (c1) LOCAL;

generates the following execution plan

0     CREATE INDEX STATEMENT Optimizer=CHOOSE
1   0   PARTITION RANGE (ALL)
2   1     INDEX BUILD (NON UNIQUE (LOCAL))
3   2       SORT (CREATE INDEX)
4   3         TABLE ACCESS (FULL) OF 'T1'
