Member Function Documentation

void drizzled::user_var_entry::update_hash	(	bool	set_null,
		data_ref	data,
		Item_result	arg_type,
		const charset_info_st *	cs,
		Derivation	dv,
		bool	unsigned_arg
	)

Set value to user variable.

Parameters:

entry	pointer to structure representing variable
set_null	should we set NULL value ?
ptr	pointer to buffer with new value
length	length of new value
type	type of new value
cs	charset info for new value
dv	derivation for new value
unsigned_arg	indiates if a value of type INT_RESULT is unsigned

Note:

Sets error and fatal error if allocation fails.

Return values:

false	success
true	failure
