Change Item_equal to operate Type_handler rather than Item_result

    XMLWordPrintable

    Details

      Description

      As of versions 10.2 and 10.3.0, the class Item_equal uses Item_result m_compare_type to store comparison type of the operation. This is not friendly to pluggable data types. To make pluggable data types use multiple equality, we'll remove m_compare_type and add const Type_handler *m_compara_handler instead.
