PARTITION RANGE (ALL)

Description

Executes child operations for each partition in the table

Versions

This operation was introduced in Oracle 8.1.5 replacing PARTITION (CONCATENATED)

This operation is implemented in the following versions

Example

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),
      PARTITION p3 VALUES LESS THAN (30),
      PARTITION p4 VALUES LESS THAN (40)
    );

The table does not need to be analysed

The statement

    SELECT c1 FROM t1;

generates the following execution plan

0     SELECT STATEMENT Optimizer=CHOOSE
1   0   PARTITION RANGE (ALL)
2   1     TABLE ACCESS (FULL) OF 'T1'
