12c Database : Multiple Partitions maintainance in one go

Before to 12c, if you want to maintain partitions you will need to execute that many alter statements partition commands that many times.

For example to add p7,p8 partitions, you have to use

SQL> alter table test_tbl add partition p7 values less than (7)
SQL> alter table test_tbl add partition p8 values less than (8)

12c has simplified this for following operations in a single Alter commmand.

	ADD Multiple partitions/SUB partitions
	DROP Multiple partitions/SUB partitions
	MERGE multiple partitions/SUB partitions
	TRUNCATE multiple partitions

Let's have a quick look

Add Multiple partitions

	SQL> alter table test_tbl add partition p7 values less than (7),partition p8 values less than(8);
	Table altered.

Drop Multiple partitions

	SQL> alter table test_tbl drop partition p7,p8;
	Table altered.

Merge Multiple partitions

	SQL>  alter table test_tbl merge partitions p7,p8 into partition p9;

	Table altered.

Split Multiple partitions

	SQL> alter table test_tbl
		split partition p9 into
		(
		  partition p7 values less than(7),
		  partition p8
		);

		Table altered.

Truncate Multiple partitions

	SQL> alter table test_tbl truncate partitions p6,p7,p8;

	Table truncated.
