Field Documentation
| que_common_t upd_node_t::common |
node type: QUE_NODE_UPDATE
| row_ext_t* upd_node_t::ext |
NULL, or prefixes of the externally stored columns in the old row
| mem_heap_t* upd_node_t::heap |
memory heap used as auxiliary storage; this must be emptied after a successful update
| dict_index_t* upd_node_t::index |
NULL, or the next index whose record should be updated
| btr_pcur_t* upd_node_t::pcur |
persistent cursor placed on the clustered index record which should be updated or deleted; the cursor is stored in the graph of 'select' field above, except in the case of the MySQL interface
| dtuple_t* upd_node_t::row |
NULL, or a copy (also fields copied to heap) of the row to update; this must be reset to NULL after a successful update
| sel_node_t* upd_node_t::select |
query graph subtree implementing a base table cursor: the rows returned will be updated
| ulint upd_node_t::state |
node execution state
| dict_table_t* upd_node_t::table |
table where updated
| upd_t* upd_node_t::update |
update vector for the row
