expand_more We can permanently rename a column in MySQL using the below syntax:
ALTER TABLE table_name CHANGE old_column_name new_column_name data_type;
Example
Consider the following table containing information about some students:
ID | Name | Age | Hobby |
|---|---|---|---|
1 | Alex | 30 | Programming |
2 | Bob | 15 | Programming |
3 | Cathy | 20 | Swimming |
The above table can be created using the code here.
To check the current table characteristics:
DESCRIBE info;
+-------+--------------+------+-----+---------+----------------+| Field | Type | Null | Key | Default | Extra |+-------+--------------+------+-----+---------+----------------+| id | int unsigned | NO | PRI | NULL | auto_increment || name | varchar(20) | YES | | NULL | || age | int | YES | | NULL | || hobby | varchar(20) | YES | | NULL | |+-------+--------------+------+-----+---------+----------------+
To rename the column name to first_name:
ALTER TABLE info CHANGE name first_name VARCHAR(20);
Query OK, 0 rows affected (0.01 sec)Records: 0 Duplicates: 0 Warnings: 0
To confirm the column has indeed been renamed:
DESCRIBE info;
+------------+--------------+------+-----+---------+----------------+| Field | Type | Null | Key | Default | Extra |+------------+--------------+------+-----+---------+----------------+| id | int unsigned | NO | PRI | NULL | auto_increment || first_name | varchar(20) | YES | | NULL | || age | int | YES | | NULL | || hobby | varchar(20) | YES | | NULL | |+------------+--------------+------+-----+---------+----------------+
