Question

I have the following table

  CREATE TABLE \"METRIC_VALUE_RAW\" 
   (    
    \"SUBELEMENT_ID\" INTEGER NOT NULL , 
    \"METRIC_METADATA_ID\" INTEGER NOT NULL ,          


        

Answer 1

Following is a sample create table sql to parititon data:

CREATE TABLE quarterly_report_status (
    report_id INT NOT NULL,
    report_status VARCHAR(20) NOT NULL,
    report_updated TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)
PARTITION BY RANGE ( UNIX_TIMESTAMP(report_updated) ) (
    PARTITION p0 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-01 00:00:00') ),
    PARTITION p1 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-02 00:00:00') ),
    PARTITION p2 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-03 00:00:00') ),
    PARTITION p3 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-04 00:00:00') ),
    PARTITION p4 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-05 00:00:00') ),
    PARTITION p5 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-06 00:00:00') ),
    PARTITION p6 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-07 00:00:00') ),
    PARTITION p7 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-08 00:00:00') ),
    PARTITION p8 VALUES LESS THAN ( UNIX_TIMESTAMP('2008-01-09 00:00:00') ),
    PARTITION p9 VALUES LESS THAN (MAXVALUE)
);

Paritions will be created by DBa and rest will be taken care of by oracle. If you want to delete partition then you will have to write separate jobs for it.
