**What Is Data Type Integer in Access?**

In Microsoft Access, the __Integer__ data type is used to store whole numbers that do not have decimal places. It is a common data type used to represent integers in a database table.

## Properties of the Integer Data Type

The Integer data type has the following properties:

**Data Size:**The Integer data type uses 2 bytes of storage space.**Value Range:**It can store whole numbers ranging from -32,768 to 32,767.**Storage:**The Integer values are stored as signed integers, which means they can be positive or negative.

## Benefits of Using the Integer Data Type

The use of the Integer data type offers several advantages:

**Economy of Space:**Since it uses only 2 bytes of storage space, it is more efficient compared to other larger integer data types like Long Integer or Double.**Faster Calculations:**Performing calculations with smaller data types like Integer is faster compared to larger ones. Therefore, if your application does not require large numbers, using the Integer data type can improve performance.

## Considerations When Using the Integer Data Type

While the Integer data type has its benefits, there are a few considerations to keep in mind:

**Data Range Limitation:**The value range for Integers (-32,768 to 32,767) may not be sufficient for certain applications that require larger numbers. In such cases, you might need to consider using larger data types like Long Integer or Double.**Loss of Precision:**Since the Integer data type does not allow decimal places, any calculations involving fractional numbers will result in a loss of precision. If your application requires precise calculations with decimal values, consider using appropriate data types like Double or Decimal.

## Examples of Using the Integer Data Type

Here are a few examples that demonstrate the usage of the Integer data type:

### Example 1:

**Create Table Employees**
(
EmployeeID __Integer__ PRIMARY KEY,
FirstName __Text(50)__,
LastName __Text(50)__,
Age __Integer__,
Salary __Currency__
);

### Example 2:

**Select * from Employees**
**Where Age >= **__30__;

In Example 1, we create a table called Employees with columns EmployeeID (Integer), FirstName (Text), LastName (Text), Age (Integer), and Salary (Currency). The Age column is defined as an Integer.

In Example 2, we retrieve all employees whose age is greater than or equal to 30 using the Age column of the Integer data type in our query.

The Integer data type in Access provides a convenient way to store whole numbers efficiently. By understanding its properties and limitations, you can make informed decisions when designing your database tables and queries.
