Constructor & Destructor Documentation

Key::Key	(	const Key &	rhs,
		MEM_ROOT *	mem_root
	)

Construct an (almost) deep copy of this key. Only those elements that are known to never change are not copied. If out of memory, a partial copy is returned and an error is set in THD.

Member Function Documentation

virtual Key* Key::clone ( MEM_ROOT *  mem_root ) const

inlinevirtual

Used to make a clone of this object for ALTER/CREATE TABLE
