Learn SQL Auto Increment Field With Syntax

1. Auto Increment in SQL

In this SQL tutorial, we are going to learn about SQL Auto Increment. We will see the meaning of SQL Auto Increment. Moreover, we will discuss MySQL Auto Increment and the syntax of SQL Server Auto Increment and SQL access.
So, let’s start the SQL Auto Increment.

SQL Auto Increment

Learn SQL Auto Increment Field With Syntax

2. What is SQL Auto Increment Field?

Auto-increment enables a kind of number to be produced automatically when another record is embedded into a table.
The SQL primary key autoincrement field is often that we might want to be made automatically every time another record is embedded.
Herre, we see SQL create table auto_inccrement. The syntax for MySQL auto increment–
Do you know about SQL Create Database System

CREATE TABLE USER_TABLE
(Userid int NOT NULL AUTO_INCREMENT,
Last_Name varchar(50),
First_Name varchar(50),
PRIMARY KEY (Userid));

3. SQL Server Auto Increment

The accompanying SQL explanation characterizes the “ID” section to be an auto-increment primary key field in the “People” table:

Make TABLE Persons (
ID int NOT NULL AUTO_INCREMENT,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
Primary KEY (ID)
);

MySQL utilizes the AUTO_INCREMENT keyword to play out an auto-increment highlight.
As a matter of course, the beginning an incentive for AUTO_INCREMENT is 1, and it will increment by 1 for each new record.
Let’s discuss SQL RDBMS Concept
To give the AUTO_INCREMENT a chance to arrangement begin with another value, utilize the accompanying SQL explanation:

Modify TABLE Persons AUTO_INCREMENT=100;

To embed another record into the “People” table, we won’t need to indicate an incentive for the “ID” section (an extraordinary value will be included automatically):

Embed INTO Persons (FirstName,LastName)
Qualities ('Lars','Monsen');

The SQL explanation above would embed another record into the “People” table. The “ID” segment would be relegated an exceptional value. The “FirstName” segment would be set to “Lars” and the “LastName” segment would be set to “Monsen”.

  • The accompanying SQL explanation characterizes the “ID” section to be an auto-increment primary key field in the “People” table:
Make TABLE Persons (
ID int IDENTITY(1,1) PRIMARY KEY,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int
);

In the case over, the beginning an incentive for IDENTITY is 1, and it will increment by 1 for each new record.
Tip: To indicate that the “ID” segment should begin at value 10 and increment by 5, change it to IDENTITY(10,5).
Let’s revise Join in SQL
To embed another record into the “People” table, we won’t need to indicate an incentive for the “ID” segment (a one of a kind value will be included automatically):

Embed INTO Persons (FirstName,LastName)
Qualities ('Lars','Monsen');

The SQL explanation above would embed another record into the “People” table. The “ID” section will appoint one of a kind value. The “FirstName” section would be set to “Lars” and the “LastName” segment would be set to “Monsen”.

4. Syntax for Access

The accompanying SQL explanation characterizes the “ID” section to be an auto-increment primary key field in the “People” table:

Make TABLE Persons (
ID Integer PRIMARY KEY AUTOINCREMENT,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int
);

The MS Access utilizes the AUTOINCREMENT catchphrase to play out an auto-increment highlight.
Naturally, the beginning an incentive for AUTOINCREMENT is 1, and it will increment by 1 for each new record.
Tip: To indicate that the “ID” section should begin at value 10 and increment by 5, change the autoincrement to AUTOINCREMENT(10,5).
Do you know about Distinct Keyword in SQL
To embed another record into the “People” table, we won’t need to indicate an incentive for the “ID” section (an interesting worth will be included automatically):

Embed INTO Persons (FirstName,LastName)
Qualities ('Lars','Monsen');

The SQL explanation above would embed another record into the “People” table. The “P_Id” section will dole out a one of a kind value. The “FirstName” segment will set to “Lars” and the “LastName” segment will set to “Monsen”.
So, this was all in SQL Auto Increment Field. Hope you like our explanation.
