Member Function Documentation

int drizzled::ReadRecord::init_read_record_idx	(	Session *	session,
		Table *	table,
		bool	print_error,
		uint32_t	idx
	)

Initialize ReadRecord structure to perform full index scan (in forward direction) using read_record.read_record() interface.

This function has been added at late stage and is used only by UPDATE/DELETE. Other statements perform index scans using join_read_first/next functions.

Parameters:

info	ReadRecord structure to initialize.
session	Thread handle
table	Table to be accessed
print_error	If true, call table->print_error() if an error occurs (except for end-of-records error)
idx	index to scan
