Example 1: How To Rename Table Using MySQL RENAME TABLE Statement

Because business requirements change, we need to rename the current table to a new one to better reflect the new situation. MySQL provides us with a very useful statement that changes the name of one or more tables.

To change one or more tables, we use the RENAME TABLE statement as follows:

RENAME TABLE old_table_name TO new_table_name;
The old table ( old_table_name) must exist, and the new table ( new_table_name) must not. If the new table new_table_name does exist, the statement will fail.

In addition to the tables, we can use the RENAME TABLE statement to rename views.

Example 2: rename table column name in mysql

ALTER TABLE table_name CHANGE old_column_name new_column_name datatype(length);
