Detailed Description
Structure for an SQL data tuple of fields (logical record)
Field Documentation
| dfield_t* dtuple_t::fields |
fields
| ulint dtuple_t::info_bits |
info bits of an index record: the default is 0; this field is used if an index record is built from a data tuple
| ulint dtuple_t::magic_n |
magic number, used in debug assertions
| ulint dtuple_t::n_fields |
number of fields in dtuple
| ulint dtuple_t::n_fields_cmp |
number of fields which should be used in comparison services of rem0cmp.*; the index search is performed by comparing only these fields, others are ignored; the default value in dtuple creation is the same value as n_fields
| ut_list_node< dtuple_t > dtuple_t::tuple_list |
data tuples can be linked into a list using this field
