RENAME TABLE

In some situations, database administrators and users want to change the name of the table in the SQL database because they want to give a more relevant name to the table.

Any database user can easily change the name by using the RENAME TABLE and ALTER TABLE statement in Structured Query Language.

The RENAME TABLE and ALTER TABLE syntax help in changing the name of the table.

Syntax of RENAME statement in SQL

RENAME old_table _name To new_table_name ;    

Examples of RENAME statement in SQL

Here, we have taken the following two different SQL examples, which will help you how to change the name of the SQL table in the database using RENAME statement:

Example 1: Let’s take an example of a table named Cars:

Hyundai i20Red9,00,000
Kia SonetWhite10,00,000

Table: Cars

  • Suppose, you want to change the above table name into “Car_2021_Details”. For this, you have to type the following RENAME statement in SQL:
RENAME Cars To Car_2021_Details ;    
  • After this statement, the table “Cars” will be changed into table name “Car_2021_Details”.

Example 2: Let’s take an example of a table named Employee:
