Constructor & Destructor Documentation

◆ alter_part_change()

alter_part_change::alter_part_change	(	uint	part_id,
		partition_state	state,
		const char *	table_name,
		const char *	tablespace,
		trx_t *	trx,
		dict_table_t **	old,
		const Alter_inplace_info *	ha_alter_info,
		bool	file_per_table,
		uint64_t	autoinc
	)

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 chraset
[in]	tablespace	Tablespace specified explicitly
[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]	ha_alter_info	ALTER information
[in]	file_per_table	Current value of innodb_file_per_table
[in]	autoinc	Next AUTOINC value to use

◆ ~alter_part_change()

alter_part_change::~alter_part_change ( )

overridedefault

Destructor.

Member Function Documentation

◆ prepare()

int alter_part_change::prepare	(	TABLE *	altered_table,
		const dd::Partition *	old_part,
		dd::Partition *	new_part
	)

overridevirtual

Prepare.

Parameters

[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

Returns: 0 or error number

Reimplemented from alter_part.

◆ rollback()

void alter_part_change::rollback ( )

inlineoverridevirtual

Rollback.

Reimplemented from alter_part.

◆ try_commit()

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

overridevirtual

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

Returns: 0 or error number

Reimplemented from alter_part.
