Detailed Description

Abstract class for functions returning TIME, DATE, DATETIME or string values, whose data type depends on parameters and is set at fix_field time.

Member Function Documentation

type_conversion_status Item_temporal_hybrid_func::save_in_field	(	Field *	field,
		bool	no_conversions
	)		`[virtual]`

Save a temporal value in packed longlong format into a Field. Used in optimizer.

Parameters:

OUT	field The field to set the value to.

Return values:

0	On success.
>0	In error.

Reimplemented from Item.

virtual bool Item_temporal_hybrid_func::val_datetime	(	MYSQL_TIME *	ltime,
		uint	fuzzy_date
	)		`[protected, pure virtual]`

Get "native" temporal value as MYSQL_TIME

Parameters:

OUT	ltime The value is stored here.
IN	fuzzy_date Date flags.

Return values:

false	On success.
true	On error.

String* Item_temporal_hybrid_func::val_str ( String * str ) [inline, virtual]

Return string value in @character_set_connection.

Implements Item.

String * Item_temporal_hybrid_func::val_str_ascii ( String * str ) [virtual]

Return string value in ASCII character set.

Reimplemented from Item.
