Description:
Currently, MySQL Server doesn't support ROWIDs, as the storage engine interface doesn't have a way to work with ROWIDs. In some cases, especially working with row-based replication, backup and restore etc, ROWIDs are useful. However, in other cases, ROWIDs are unnecessary and they could be just an overhead.

The best usage is that users can choose whether they use ROWID or not when creating a table like below:

mysql> CREATE TABLE tbl (...) ENGINE=MYISAM ROWID=BIGINT;

Without specifying ROWID option, ROWIDs should not be created.

ROWIDs should be accessed as `ROWID` or ROWID() in SQL statements. How they are stored should depend on a storage engine implementation.

How to repeat:
n/a

Suggested fix:
n/a
