RENAME TABLE

RENAME TABLE tbl_name TO new_tbl_name
[, tbl_name2 TO new_tbl_name2] ...
The RENAME operation is performed atomically. No other session can access the table while it is being renamed.
Renaming operations occur from left to right. To swap two table names, you can use:
RENAME TABLE old_table TO tmp_table,
new_table TO old_table,
tmp_table TO new_table;
You can RENAME TABLE to move a table from one database to another:
RENAME TABLE this_db.tbl_name TO that_db.tbl_name;
You cannot RENAME a TEMPORARY table.
