MySQL Reset Next Autoindex helps reset the AUTO_INCREMENT field in a jiffy. Find out how.

At Bobcares, we offer solutions for every query, big and small, as a part of our MySQL Support Services.

Let’s take a look at how our MySQL Support Team is ready to help customers with MySQL Reset Next Autoindex.

What is MySQL Reset Next Autoindex

The AUTO_INCREMENT attribute in MySQL helps us reset sequences. In other words, we can use this MySQL attribute to reset the value via the ALTER TABLE statement as seen below:

ALTER TABLE table_name AUTO_INCREMENT = value;

• table_name indicates the name of the table where we want to reset the AUTO INCREMENT column.
• value indicates the next value to be used in the AUOT_INCREMENT column.

Let’s take a look at an example to get a clearer idea about this MySQL Reset Next Autoindex.

For instance, if we have a customers table as seen below:

CREATE TABLE customers
( customer_id INT(11) NOT NULL AUTO_INCREMENT,
  customer_name VARCHAR(50) NOT NULL,
  account_rep VARCHAR(30) NOT NULL DEFAULT 'TBD',
  CONSTRAINT customers_pk PRIMARY KEY (supplier_id)
);

In this scenario, we can reset the next value for the customer_id field (the AUTO_INCREMENT field here) with the following statement:

ALTER TABLE customers AUTO_INCREMENT = 16342;

As a result of the above statement, the next value in the sequence will change to 16342 for the customer_id column in the customers table. In other words, the next time a new record is added to the customers table, the customer_id column will have the value 16342 for the new record.

Our Support Team would like to point out that a table can have only one AUTO_INCREMENT field. This is why we do not have to mention the field name in the ALTER TABLE statement. In brief, the MySQL Reset Next Autoindex parameter comes in handy when we delete rows in the table and have unsynchronized values in the table.
