The **integer data type** in PostgreSQL is used to store whole numbers without any decimal places. It is a commonly used data type for representing numeric values in a database.

## Creating an Integer Column

When creating a table in PostgreSQL, you can define a column with the integer data type using the following syntax:

CREATE TABLE table_name (
column_name INTEGER
);

In this example, the __column_name__ is defined as an integer data type.

## Inserting Integer Values

To insert integer values into an integer column, you can use the **INSERT INTO** statement. Here’s an example:

INSERT INTO table_name (column_name)
VALUES (10);

This will insert the value 10 into the __column_name__ of the specified table.

## Operations with Integer Data Type

The integer data type supports various mathematical operations such as addition, subtraction, multiplication, and division. Here are some examples:

SELECT column_name + 5 FROM table_name;

**Subtraction:**
SELECT column_name - 5 FROM table_name;

**Multiplication:**
SELECT column_name * 5 FROM table_name;

**Division:**
SELECT column_name / 5 FROM table_name;

## Data Range of Integer

The integer data type in PostgreSQL can store values ranging from -2147483648 to 2147483647. This range covers a wide range of whole numbers, allowing you to store large and small integer values.

## Summary

In summary, the integer data type in PostgreSQL is used to store whole numbers without any decimal places. It supports various mathematical operations and has a wide range of values that can be stored. By using the integer data type, you can efficiently store and manipulate numeric values in your PostgreSQL database.
