		const CHARSET_INFO *	cs
	)

Builder for cast expressions.

Parameters:

thd	The current thread
a	The item to cast
cast_type	the type casted into
len	TODO
dec	TODO
cs	The character set

Item* create_temporal_literal	(	THD *	thd,
		const char *	str,
		uint	length,
		const CHARSET_INFO *	cs,
		enum_field_types	type,
		bool	send_error
	)

Builder for datetime literals: TIME'00:00:00', DATE'2001-01-01', TIMESTAMP'2001-01-01 00:00:00'.

Parameters:

thd	The current thread
str	Character literal
length	Length of str
type	Type of literal (TIME, DATE or DATETIME)
send_error	Whether to generate an error on failure

Create_func* find_native_function_builder	(	THD *	thd,
		LEX_STRING	name
	)
