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.
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;
- Change the name of column NAME to FIRST_NAME in table Student.
ALTER TABLE Student RENAME COLUMN NAME TO FIRST_NAME;
- Change the name of the table Student to Student_Details
ALTER TABLE Student RENAME TO Student_Details;
