Member Function Documentation

void Field_temporal_with_date_and_timef::make_sort_key	(	uchar *	buff,
		uint	length
	)		[inline, virtual]

Writes a copy of the current value in the record buffer, suitable for sorting using byte-by-byte comparison. Integers are always in big-endian regardless of hardware architecture. At most length bytes are written into the buffer.

Parameters:

buff	The buffer, assumed to be at least length bytes.
length	Number of bytes to write.

Implements Field.
