void Protocol_local::prepare_for_resend ( )

protectedvirtual

Called between two result set rows.

Prepare structures to fill result set rows. Unfortunately, we can't return an error here. If memory allocation fails, we'll have to return an error later. And so is done in methods such as

See Also: store_column().

Implements Protocol.

Definition at line 4322 of file sql_prepare.cc.

bool Protocol_local::send_eof	(	uint	server_status,
		uint	statement_warn_count
	)

protectedvirtual

Called at the end of a result set. Append a complete result set to the list in Ed_connection.

Don't send anything to the client, but instead finish building of the result set at hand.

Reimplemented from Protocol.

Definition at line 4609 of file sql_prepare.cc.

bool Protocol_local::send_error	(	uint	sql_errno,
		const char *	err_msg,
		const char *	sqlstate
	)

protectedvirtual

Called to send an error to the client at the end of a statement.

Reimplemented from Protocol.

Definition at line 4641 of file sql_prepare.cc.

bool Protocol_local::send_ok	(	uint	server_status,
		uint	statement_warn_count,
		ulonglong	affected_rows,
		ulonglong	last_insert_id,
		const char *	message
	)

protectedvirtual

Called for statements that don't have a result set, at statement end.

Reimplemented from Protocol.

Definition at line 4589 of file sql_prepare.cc.

bool Protocol_local::send_out_parameters ( List< Item_param > * sp_params )

protectedvirtual

Normally this is a separate result set with OUT parameters of stored procedures. Currently unsupported for the local version.

Implements Protocol.

Definition at line 4580 of file sql_prepare.cc.

bool Protocol_local::send_result_set_metadata	(	List< Item > *	columns,
		uint	flags
	)

protectedvirtual

Called to start a new result set.

Reimplemented from Protocol.

Definition at line 4559 of file sql_prepare.cc.

bool Protocol_local::store	(	const char *	str,
		size_t	length,
		const CHARSET_INFO *	src_cs
	)

protectedvirtual

Convert to cs_results and store a string.

Implements Protocol.

Definition at line 4485 of file sql_prepare.cc.

bool Protocol_local::store	(	const char *	str,
		size_t	length,
		const CHARSET_INFO *	src_cs,
		const CHARSET_INFO *	dst_cs
	)

protectedvirtual

Store a string.

Implements Protocol.

Definition at line 4497 of file sql_prepare.cc.

bool Protocol_local::store_date ( MYSQL_TIME * time )

protectedvirtual

Store MYSQL_TIME (in binary format)

Implements Protocol.

Definition at line 4516 of file sql_prepare.cc.

bool Protocol_local::store_decimal ( const my_decimal * value )

protectedvirtual

Store a decimal in string format in a result set column

Implements Protocol.

Definition at line 4468 of file sql_prepare.cc.

bool Protocol_local::store_long ( longlong value )

protectedvirtual

Store a "long" as is (4 bytes, host order) in a result set column.

Implements Protocol.

Definition at line 4450 of file sql_prepare.cc.

bool Protocol_local::store_longlong	(	longlong	value,
		bool	unsigned_flag
	)

protectedvirtual

Store a "longlong" as is (8 bytes, host order) in a result set column.

Implements Protocol.

Definition at line 4459 of file sql_prepare.cc.

bool Protocol_local::store_null ( )

protectedvirtual

Add a NULL column to the current row.

Implements Protocol.

Definition at line 4366 of file sql_prepare.cc.

bool Protocol_local::store_short ( longlong value )

protectedvirtual

Store a short as is (2 bytes, host order) in a result set column.

Implements Protocol.

Definition at line 4441 of file sql_prepare.cc.

bool Protocol_local::store_time	(	MYSQL_TIME *	time,
		uint	precision
	)

protectedvirtual

Store MYSQL_TIME (in binary format)

Implements Protocol.

Definition at line 4524 of file sql_prepare.cc.

bool Protocol_local::store_tiny ( longlong value )

protectedvirtual

Store a tiny int as is (1 byte) in a result set column.

Implements Protocol.

Definition at line 4432 of file sql_prepare.cc.

bool Protocol_local::write ( )

protectedvirtual

In "real" protocols this is called to finish a result set row. Unused in the local implementation.

Reimplemented from Protocol.

Definition at line 4339 of file sql_prepare.cc.
