Why BETWEEN Operator is Used in SQL?

In SQL, the BETWEEN operator is used to make it easier to find data within a specific range. It’s like setting boundaries for your search. Let’s break it down in simple terms:

Points to Understand about the BETWEEN Operator in SQL:

Point	Explanation
1.	What is BETWEEN?<br> The BETWEEN operator checks if a value is within a specified range of values. It helps us find data that falls between two values.
2.	How to Use BETWEEN?<br> You use it like this: column_name BETWEEN value1 AND value2. SQL will then fetch data where the column value is within this range.
3.	Inclusive Range<br> BETWEEN includes the values specified in the range. So, if you use BETWEEN 1 AND 5, it includes both 1 and 5 in the results.
4.	Use with Numbers and Dates<br> You can use BETWEEN with numbers, dates, and even text (if it’s in a way that can be compared).
5.	Easier Than Multiple Conditions<br> It’s much easier to use BETWEEN than to write multiple conditions like column_name >= value1 AND column_name <= value2.
6.	Avoiding Errors<br> Using BETWEEN can help you avoid mistakes when specifying a range, making your queries more reliable.

Brief Summary:

• BETWEEN checks if a value is within a specified range.
• You use it like this: column_name BETWEEN value1 AND value2.
• It includes both value1 and value2 in the results.
• You can use it with numbers, dates, and sometimes text.
• It’s easier and less error-prone than writing multiple conditions.

So, when you want to find data within a certain range in SQL, remember to use the BETWEEN operator. It makes your queries simpler and more precise.

EXAMPLE OF BETWEEN OPERATOR IN SQL

let’s use an example to illustrate how the BETWEEN operator works in SQL.

Suppose you have a table called “Sales” with a column named “SaleAmount,” and you want to find all the sales that fall within a specific price range.

Here’s how you can use the BETWEEN operator:

SELECT * FROM Sales WHERE SaleAmount BETWEEN 1000 AND 5000;

In this SQL query:

• SELECT * means you want to select all columns for the matching rows.
• FROM Sales specifies the table you are querying.
• WHERE SaleAmount BETWEEN 1000 AND 5000 is where the magic happens. This part of the query tells SQL to retrieve all rows from the “Sales” table where the “SaleAmount” is between $1000 and $5000.

The result will be a list of sales that fall within the specified price range, including those with a sale amount of $1000 and $5000.

That’s how you use the BETWEEN operator in SQL to filter data within a specific range.
