PARTITION (CONCATENATED)

Description

Executes child operations for each partition in the table

Versions

This operation was introduced in Oracle 8.0.4. It was replaced by PARTITION RANGE (ALL), PARTITION RANGE (INLIST) and PARTITION RANGE (ITERATOR) in Oracle 8.1.5

This operation is implemented in the following versions

8.0.4
8.0.5
8.0.6

Example

Example 1

This is an example of the operation that was replaced by PARTITION RANGE (ALL) in Oracle 8.1.5

This example was developed using Oracle 8.0.6

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 (CONCATENATED)
2   1     TABLE ACCESS (FULL) OF 'T1'
Example 2

This is an example of the operation that was replaced by PARTITION RANGE (INLIST) in Oracle 8.1.5

This example was developed using Oracle 8.0.6

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
    WHERE c1 IN (10,20);

generates the following execution plan 

0     SELECT STATEMENT Optimizer=CHOOSE
1   0   PARTITION (CONCATENATED)
2   1     TABLE ACCESS (FULL) OF 'T1'
Example 3

This is an example of the operation that was replaced by PARTITION RANGE (ITERATOR) in Oracle 8.1.5

This example was developed using Oracle 8.0.6

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
    WHERE c1 > 8 AND c1 < 12;

generates the following execution plan 

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