Detailed Description

Class which handles the partition of states PART_TO_BE_DROPPED, PART_TO_BE_REORGED and PART_REORGED_DROPPED.

See comments for alter_part_factory::create_for_reorg and alter_part_factory::create_for_non_reorg.

Constructor & Destructor Documentation

alter_part_drop::alter_part_drop	(	uint	part_id,
		partition_state	state,
		const char *	table_name,
		trx_t *	trx,
		dict_table_t **	old,
		bool	conflict
	)

inline

Constructor.

Parameters

[in]	part_id	Partition id in the table. This could be partition id for either old table or new table, callers should remember which one is applicable
[in]	state	Partition state of the partition on which this class will do operations. If this is for one partition in new table, the partition state is the same for both the new partition and the corresponding old partition
[in]	table_name	Partitioned table name, in the form of db/table, which already considers the charset
[in,out]	trx	InnoDB transaction
[in,out]	old	InnoDB table object for old partition, default is nullptr, which means there is no corresponding object
[in]	conflict	True if there is already a partition table with the same name

Destructor.

int alter_part_drop::try_commit	(	const TABLE *	table,
		TABLE *	altered_table,
		const dd::Partition *	old_part,
		dd::Partition *	new_part
	)

inlineoverridevirtual

Try to commit.

Parameters

[in]	table	Table definition before the ALTER
[in,out]	altered_table	Table definition after the ALTER
[in]	old_part	the stored old partition or nullptr if no corresponding one exists
[in,out]	new_part	the stored new partition or nullptr if no corresponding one exists

Reimplemented from alter_part.

const bool alter_part_drop::m_conflict

private

True if there is already a partition table with the same name.
