SQL | ALTER (RENAME)

Sometimes we may want to rename our table to give it a more relevant name. For this purpose we can use ALTER TABLE to rename the name of table.
*Syntax may vary in different databases.

Syntax(Oracle,MySQL,MariaDB):

ALTER TABLE table_name
RENAME TO new_table_name;

Columns can be also be given new name with the use of ALTER TABLE.

ALTER TABLE table_name
RENAME COLUMN old_name TO new_name;

ALTER TABLE table_name
CHANGE COLUMN old_name TO new_name;
