RENAME TABLE tbl_name TO new_tbl_name [, tbl_name2 TO new_tbl_name2] ...
For example, to rename a table named
new_table, use this statement:
RENAME TABLE old_table TO new_table;
That statement is equivalent to the following
ALTER TABLE statement:
ALTER TABLE old_table RENAME new_table;
RENAME TABLE, unlike
TABLE, can rename multiple tables within a single
RENAME TABLE old_table1 TO new_table1, old_table2 TO new_table2, old_table3 TO new_table3;
Renaming operations are performed left to right. Thus, to swap two
table names, do this (assuming that a table with the intermediary
tmp_table does not already exist):
RENAME TABLE old_table TO tmp_table, new_table TO old_table, tmp_table TO new_table;
RENAME TABLE, there must be no
active transactions or tables locked with
TABLES. With the transaction table locking conditions
satisfied, the rename operation is done atomically; no other
session can access any of the tables while the rename is in
If any errors occur during a
RENAME TABLE, the
statement fails and no changes are made.
You can use
RENAME TABLE to move a table from
one database to another:
RENAME TABLE current_db.tbl_name TO other_db.tbl_name;
Using this method to move all tables from one database to a different one in effect renames the database (an operation for which MySQL has no single statement), except that the original database continues to exist, albeit with no tables.
ALTER TABLE ...
RENAME can also be used to move a table to a different
database. Regardless of the statement used, if the rename
operation would move the table to a database located on a
different file system, the success of the outcome is platform
specific and depends on the underlying operating system calls used
to move table files.
If a table has triggers, attempts to rename the table into a
different database fail with a Trigger in wrong
TABLE does not work. Use
RENAME TABLE works for views, except that views
cannot be renamed into a different database.
Any privileges granted specifically for a renamed table or view are not migrated to the new name. They must be changed manually.
RENAME TABLE changes internally generated
foreign key constraint names and user-defined foreign key
constraint names that contain the string
reflect the new table name.
foreign key constraint names that contain the string
internally generated names.
Foreign key constraint names that point to the renamed table are automatically updated unless there is a conflict, in which case the statement fails with an error. A conflict occurs if the renamed constraint name already exists. In such cases, you must drop and re-create the foreign keys for them to function properly.
