To change the default starting value we can use ALTER TABLE command as follows: ALTER TABLE Students AUTO_INCREMENT = new_value INSERT INTO Students(First_Name, Last_Name ) To insert a new record into students table, we will not specify the value of Student_ID as it will be added automatically and the first record will have key as 1 and key for every subsequent record will increase by 1. Student_ID int AUTO_INCREMENT PRIMARY KEY, We will create Students table with fields Student_ID, First_Name, Last_Name, we will auto generate Student_ID by using auto increment and will make it Primary Key for the table. By default, the AUTO_INCREMENT starts with 1 and increases by 1. In MySQL, AUTO_INCREMENT keyword is employed for auto increment feature. ![]() To insert a new record into students table, we will not specify the value of Student_ID as it will be added automatically. Student_ID int IDENTITY(101, 1) PRIMARY KEY, Let the starting value of IDENTITY be 101 and we will increment the auto generated key by 1 for each new record. Mention the value by which we would like to increment the key for the subsequent record. Mention the starting value we would like to use. In SQL Server, IDENTITY(starting_value, increment_value) is used for auto increment feature. The Auto Increment feature is supported by all the Databases we are going to discuss the auto increment field for the subsequent DBMS: Introduction of 3-Tier Architecture in DBMS | Set 2.Difference between Primary key and Unique key.Difference between DELETE, DROP and TRUNCATE.Types of Keys in Relational Model (Candidate, Super, Primary, Alternate and Foreign).Difference between Clustered and Non-clustered index.Difference between Primary Key and Foreign Key.Commonly asked DBMS interview questions.Introduction of DBMS (Database Management System) | Set 1.SQL query to find second highest salary?.SQL | Join (Inner, Left, Right and Full Joins).ISRO CS Syllabus for Scientist/Engineer Exam. ![]()
