Rename a column in MySQL

Question

I am trying to rename a column in MySQL community server 5.5.27 using this SQL expression:

ALTER TABLE table_name R         


        

Answer 1

From MySQL 5.7 Reference Manual.

Syntax :

ALTER TABLE t1 CHANGE a b DATATYPE;

e.g. : for Customer TABLE having COLUMN customer_name, customer_street, customercity.

And we want to change customercity TO customer_city :

alter table customer change customercity customer_city VARCHAR(225);

Answer 2

for mysql version 5

alter table *table_name* change column *old_column_name* *new_column_name* datatype();

Answer 3

From MySQL 8.0 you could use

ALTER TABLE table_name RENAME COLUMN old_col_name TO new_col_name;

ALTER TABLE Syntax:

RENAME COLUMN:

• Can change a column name but not its definition.

• More convenient than CHANGE to rename a column without changing its definition.
