inline

Constructor.

Parameters

[in]	thd	THD object
[in]	name	normalized table name
[in]	form	Table format; columns and index information
[in]	dd_table	dd::Table or dd::Partition
[in]	keep_autoinc	true to remember original autoinc counter
[in]	table_truncate	true if this is full table truncate

◆ ~innobase_truncate()

template<typename Table >

template innobase_truncate< Table >::~innobase_truncate ( )

Destructor.

Member Function Documentation

◆ cleanup()

template<typename Table >

void innobase_truncate< Table >::cleanup ( void )

private

Cleanup.

◆ exec()

template<typename Table >

template int innobase_truncate< Table >::exec ( )

Do the truncate of the table/partition.

Returns: error number or 0 on success

◆ load_fk()

template<typename Table >

int innobase_truncate< Table >::load_fk

private

Reload the FK related information.

Returns: error number or 0 on success

◆ open_table()

template<typename Table >

template int innobase_truncate< Table >::open_table ( dict_table_t *& innodb_table )

Open the table/partition to be truncated.

Parameters

[out] innodb_table InnoDB table object opened

Returns: error number or 0 on success

◆ prepare()

template<typename Table >

int innobase_truncate< Table >::prepare

private

Prepare for truncate.

Returns: error number or 0 on success

◆ rename_tablespace()

template<typename Table >

int innobase_truncate< Table >::rename_tablespace

private

Rename tablespace file name.

Returns: error number or 0 on success

◆ truncate()

template<typename Table >

int innobase_truncate< Table >::truncate

private

Do the real truncation.

Returns: error number or 0 on success

Member Data Documentation

◆ m_create_info

template<typename Table >

HA_CREATE_INFO innobase_truncate< Table >::m_create_info

private

Create information.

◆ m_dd_table

template<typename Table >

Table* innobase_truncate< Table >::m_dd_table

private

dd::Table or dd::Partition

◆ m_file_per_table

template<typename Table >

bool innobase_truncate< Table >::m_file_per_table

private

True if this table/partition is file per table.

◆ m_flags

template<typename Table >

uint32_t innobase_truncate< Table >::m_flags

private

flags of the table to be truncated, which should not change

◆ m_flags2

template<typename Table >

uint32_t innobase_truncate< Table >::m_flags2

private

flags2 of the table to be truncated, which should not change

◆ m_form

template<typename Table >

TABLE* innobase_truncate< Table >::m_form

private

Table format.

◆ m_keep_autoinc

template<typename Table >

bool innobase_truncate< Table >::m_keep_autoinc

private

True if the original autoinc counter should be kept.

It's specified by caller, however if the table has no AUTOINC column, it would be reset to false internally

◆ m_name

template<typename Table >

const char* innobase_truncate< Table >::m_name

private

Normalized table name.

◆ m_table

template<typename Table >

dict_table_t* innobase_truncate< Table >::m_table

private

InnoDB table object for the table/partition.

◆ m_table_truncate

template<typename Table >

bool innobase_truncate< Table >::m_table_truncate

private

For a prtition table, this is true if full table is truncated.

If only a partition is truncated, it is set to false.

◆ m_thd

template<typename Table >

THD* innobase_truncate< Table >::m_thd

private

THD object.

◆ m_trx

template<typename Table >

trx_t* innobase_truncate< Table >::m_trx

private

Transaction attached to current thd.
