ALTER TABLE...SET INTERVAL v13

Use the ALTER TABLE… SET INTERVAL command to convert an existing range-partitioned table to an interval range partitioned table. The database automatically creates a new partition of a specified range or interval for the partitioned table when INTERVAL is set. The syntax is:

ALTER TABLE <table_name> SET INTERVAL (<constant> | <expression>);

To disable an interval range partitioned table and convert it to a range-partitioned table, the syntax is:

ALTER TABLE <table_name> SET INTERVAL ();

Parameters

table_name

The name (optionally schema-qualified) of the range-partitioned table.

constant | expression

Specifies a NUMERIC, DATE, or TIME value.

Description

The ALTER TABLE… SET INTERVAL command can be used to convert the range-partitioned table to use interval range partitioning. A new partition of a specified interval is created and data can be inserted into the new partition.

The SET INTERVAL () command can be used to disable interval range partitioning. The database converts an interval range partitioned table to range-partitioned and sets the boundaries of the interval range partitions to the boundaries for the range partitions.
