I need to copy three tables and rename them in the same MySQL database. Does anyone know a statement I can execute, or do I need to export and import?

Answer is here on StackOverflow, hidden under a database rename operation (databases can be renamed by creating a new database, then “moving” the tables).

RENAME TABLE db.table TO db.table;From the comments: “I’ve just done this with an InnoDB database with 30+ tables, using the file_per_table setting, and even though some tables were 3+ million rows, it completed in < 1 second. It just seems to move the files on the storage, rather than doing anything more complicated… +2 if possible :)”.
