Member Function Documentation

◆ abort_result_set()

void Query_result_create::abort_result_set ( THD * thd )

overridevirtual

Reimplemented from Query_result_insert.

◆ binlog_show_create_table()

int Query_result_create::binlog_show_create_table ( THD * thd )

private

◆ create_table_for_query_block()

bool Query_result_create::create_table_for_query_block ( THD * thd )

overridevirtual

Create new table.

Parameters

thd	thread handler

Returns: false on success, true on error

Reimplemented from Query_result.

◆ drop_open_table()

void Query_result_create::drop_open_table ( THD * thd )

private

Close and drop just created table in CREATE TABLE ... SELECT in case of error.

Note: Here we assume that the table to be closed is open only by the calling thread, so we needn't wait until other threads close the table. We also assume that the table is first in thd->open_ables and a data lock on it, if any, has been released.

◆ prepare()

bool Query_result_create::prepare	(	THD *	,
		const mem_root_deque< Item * > &	,
		Query_expression *	u
	)

overridevirtual

Perform preparation specific to the query expression or DML statement.

Returns: false if success, true if error

Reimplemented from Query_result_insert.

◆ send_eof()

bool Query_result_create::send_eof ( THD * thd )

overridevirtual

Reimplemented from Query_result_insert.

◆ set_two_fields()

void Query_result_create::set_two_fields	(	HA_CREATE_INFO *	create_info_arg,
		Alter_info *	alter_info_arg
	)

inline

◆ start_execution()

bool Query_result_create::start_execution ( THD * thd )

overridevirtual

Lock the newly created table and prepare it for insertion.

Reimplemented from Query_result_insert.

◆ stmt_binlog_is_trans()

bool Query_result_create::stmt_binlog_is_trans ( ) const

overrideprivatevirtual

Indicates whether this statement should be written to binary log's transactional cache in statement mode.

Reimplemented from Query_result_insert.

◆ store_values()

void Query_result_create::store_values	(	THD *	thd,
		const mem_root_deque< Item * > &	values
	)

overridevirtual

Reimplemented from Query_result_insert.
