I'd like to use the _rowid capability of MySQL to improve the efficiency of a project, but I have concerns about the reliability of the number it returns. I understand that _rowid "may change over time depending on many factors," but I'd like to know whether this is true if the row is locked. In particular, can I perform a select on a row which returns a _rowid, modify the row data, and later do an UPDATE using the _rowid as index, without worrying that the _rowid has changed? Any help will be much appreciated.
