Function Documentation

UNIV_INTERN ulint row_undo_ins

(

undo_node_t *

node

)

Undoes a fresh insert of a row to a table. A fresh insert means that the same clustered index unique key did not have any record, even delete marked, at the time of the insert. InnoDB is eager in a rollback: if it figures out that an index record will be removed in the purge anyway, it will remove it in the rollback.

Returns:

DB_SUCCESS in: row undo node
