Between Operator in SQL Syntax and Usage

Ever felt stuck writing long SQL conditions just to get basic results? Imagine having a magic filter that knows exactly what you want, no fuss, no repetition. That is the power of the BETWEEN Operator in SQL. It slices through data like a pro, giving you clean, accurate results with just one neat condition.

The BETWEEN Operator in SQL is a simple way to filter data by range. In this blog, you’ll learn how to use numbers, text, and dates. We’ll also cover its syntax, how it works with NOT and IN and how it differs from SQL functions. Let’s dive in!

What is the BETWEEN Operator in SQL?

The BETWEEN Operator helps identify and revert to rows that fall to a certain extent. When used in a SELECT statement, it involves both the starting and ending values. You can use it with integers, dates or text.

This is the syntax of SQL BETWEEN Operator:

The output will be a list of values from column_name that fall within the inclusive range of value1 and value2.

The Syntax for Using the SQL BETWEEN Operators

This Structured Query Language (SQL) Operator is commonly used with the SELECT command. The syntax of this is as follows:

When we are writing Basic SQL queries, we should keep a few small things in mind. First, list the columns you want to see in the SELECT area. Then next one, use the FROM part to mention which table data comes from. This assists SQL in knowing what to pull and from which place.

When you want to verify if a value falls into a certain range, use the BETWEEN Operator in the WHERE scope. Just write the column name continued by the first and last values. This will help to filter results easily without writing long conditions. It works well with integers, dates and even text.

Using the NOT Operator With BETWEEN

We can use the NOT Operator and the BETWEEN Operator to select the values not included in a specified range. To accomplish this, we replace the BETWEEN keyword with NOT BETWEEN in the syntax mentioned above.

For example, let's assume you have a database table called "Products" with a column named "Price," and you want to find all products whose prices are NOT BETWEEN 10 and 50. Here's an example SQL query to achieve that:

Using BETWEEN With Numeric Values

The "BETWEEN" Operator is often used with numeric values to filter records within a specific range. Here's an example using SQL to find all products with prices BETWEEN 10 and 50 in a "Products" table:

In the above SQL query:

a) SELECT * selects all columns from the "Products" table.

b) FROM Products specifies the table we're querying, which is "Products" in this case.

c) WHERE Price BETWEEN 10 AND 50 filters the outcomes to include only rows where the "Price" column falls within the 10 to 50 range.

Using BETWEEN With Date Values

Using the "BETWEEN" Operator with date values filters records within a specific date range. Here's an example using SQL to find all orders arranged BETWEEN January 1, 2023, and December 31, 2023, in an "Orders" table:

Using BETWEEN With Text

The "BETWEEN" Operator is typically used with numeric or date values, and it's not commonly used with text or string values for range filtering. However, you can achieve similar results with string comparisons.

Suppose you have a database table called "Products" with a column named "Category" containing text values, and you want to retrieve products within a specific range of categories (e.g., categories starting with 'A' to 'M'). Here's an example in SQL:

Using BETWEEN With the SQL In Operator

The "BETWEEN" Operator and the "IN" Operator are typically used separately, but you can use them together in certain scenarios. These SQL Operators help refine queries by filtering data based on specific conditions. For example, you might want to retrieve records that are within a numeric range and also match specific values using the "IN" Operator.

Suppose you have a database table called "Products" with a "Price" column and you want to retrieve products that are either in the price range of 10 to 50 or have specific IDs. You can use both Operators like this in SQL:

What SQL Data Types can I use with the BETWEEN Operator?

The BETWEEN Operator supports multiple data types, making it very versatile. You can use it with:

1) Numbers

2) Text (strings)

3) Dates

What is the Difference Between Operator and Function in SQL?

In SQL, operators and functions serve different purposes:

1) Operators: BETWEEN, IN, =, >, and AND are used to compare values and filter results in queries. They work directly within conditions in SQL statements.

2) Functions: SUM(), COUNT(), and NOW() perform operations on data and return results, such as totals or current dates.

Conclusion

The BETWEEN Operator in SQL gives a clear and effective method to filtrate data within set areas. It works smoothly with numbers, text and dates. It makes it a useful and versatile tool for writing clean and readable queries. Understanding how to use it accurately can improve both the speed and accuracy of your SQL queries.
