Key_part_spec* Key_part_spec::clone ( MEM_ROOT *  mem_root) const [inline]

Construct a copy of this Key_part_spec. field_name is copied by-pointer as it is known to never change. At the same time 'length' may be reset in mysql_prepare_create_table, and this is why we supply it with a copy.

If out of memory, 0 is returned and an error is set in THD.
