SQL BETWEEN: Retrieve Desired Range of Values with Examples [2022]

Introduction

SQL is the most popular language for data work in 2022. 

Virtually all big tech companies use SQL. Even Fortune 500 companies that have built their own high-performance database systems ( Amazon, Facebook, Google, Netflix ) still frequently use SQL to query data and perform analysis. 

One of the unique features of SQL is that it provides firms with numerous tools that help them recover valuable information from all kinds of data. Sometimes they have to get a range of values from a table's column values. This is where the SQL Between operator simplifies performing these activities (the activities can be in the form of numeric value, text value, and date) and thus becomes an integral part of this query language.

In this blog, we will be discussing the following in-depth to assist you in understanding SQL Between Operators from scratch.

  • What is SQL Between Operators?
  • SQL Between Operator with Examples
  • SQL Skills in Demand
  • What’s the Future of SQL & SQL Databases?

Yet, much depends on the certification you hold, so give a jumpstart to your Cloud professional career by enrolling yourself in a comprehensive SQL Certification & Training today! 

Let's Begin!

What Is Between in SQL?

The SQL Between operator is used to check if an expression falls within a value range.  This operator is all-inclusive, so it includes the start and end values of the range. Values may be textual, numeric, or date type.

This operator can be used with SELECT, INSERT, UPDATE, and DELETE commands. To obtain a clearer picture of SQL between operators, let's have a preview of its syntax.

The Syntax for Using the SQL Between Operator

This operator is most often used together with the SELECT command. The syntax is

SELECT command

The columns to be retrieved are specified in the SELECT statement.

  • The table from which the columns are extracted is specified within the FROM statement.

  • The BETWEEN operator is included in the WHERE clause. The column on which we want to apply the range condition is specified in the “column_names”. The starting value of the range of values is specified in the “start_range” parameter and the ending value in the “end_range” parameter.

For example, let’s take a sample “Employee details” table:

“Employee details” table

From this table, if we want to retrieve the ID and name of the employees with ID in the range of 3 to 6, we’ll use the following query:

employees with ID

This will be the output of the SQL server Between

SQL server Between

As we can see, the result contains ID values 3 and 6 as well, as Between is inclusive.

Using the Not Operator With Between

NOT is a logical operator in SQL that you can place ahead of any conditional statement to select rows for which that statement is not true.

Alternatively, we can use the NOT operator with the BETWEEN operator to select values that do not fall within the specified range. This is done using the NOT BETWEEN keyword rather than the BETWEEN keyword in the above syntax. 

For example, Using the SQL Server Between from the sample table, we can retrieve all the employees' ID and salary, with the salary not in the range 30000$ to 60000$:

Not Operator With Between

This will be the output of the following:

Using Between With Numeric Values

In this SQL between operator, you can use the ORDER BY statement to sort the result in some columns. 

For instance, the SQL keyword between is used in the sample table, to retrieve the ID, name, and salary of all employees with wages ranging from 50,000 to 80,000:

 Numeric Values

This will result in the following:

 SQL between operator

Using Between With Date Values

When using SQL date between, we need to remember to include the date in a single inverted comma; otherwise, the query returns a syntax error. 

Here is a classic example of SQL between two dates. From the table "Employment details", the objective is to recover the identity, the name, and the date of birth of employees born in the years 1994 to 1997:

SQL date between

This will be the output after the use of SQL Between DateTime is:

SQL Between DateTime

It is essential to specify the correct values for the beginning and end positions of the range.

Let’s see what happens when we don’t do that:

SQL Date Between

As we can see, the SQL Date Between mentioned above returns a blank set because the range values were incorrectly specified.

Using Between With Text

The SQL Between operator can also be used with character data types. Using this on the text, we have to remember to enclose the data in a single inverted comma, otherwise, the request returns a syntax error.

From the sample tables, the SQL keyword Between is used to retrieve all the employees' IDs and names with names belonging to the range ‘PARKER’ to ‘MADISON’:

Using Between With Text

This will be the output of the Between in MySQL: 

output of the Between in MySQL:

Let’s see what happens when we don’t enclose the data in inverted commas:

data in inverted commas

As we can see, the query returns a syntax error.

Using Not Between on Values

The SQL Not Between operator is used to get the values as part of the result set which is outside of the range specified by the SQL Between operator.

From the sample table, the aim is to retrieve the ID, name, and DOB of all the employees not born in the range 1st  Jan 1997 to 12th  Nov 2000:

Between on Values

This will be the output of the following:

As we can see, all rows that do not fall in the specified range are returned.

SQL is an extensive domain, if you’re looking for your first job in data, it turns out knowing SQL is even more critical. Check out our Comprehensive Guide on SQL to get a better insight.

Using Between With the SQL In Operator

The SQL In operator is used to specify several values in a WHERE clause and is an alternate for several OR conditions. 

The syntax for using this operator with SQL Between is:

SQL Between

 

The SQL In operator can be used to check if the values selected in the column specified in the column_2 parameter belong to the desired values, which can be specified in parentheses following the IN keyword. We can also select values that do not belong to the values given in parentheses by using the keyword Not In instead of the keyword In.

Let’s see some examples of this.

From the sample table, the aim is to retrieve the ID, name, and wages of all the employees with names in the range ‘A’ to ‘J’ and ID belonging to the values 1, 2, 4, or 8:

retrieve the ID, name, and wages

This will be the output of the following:  

Let’s see what happens when we use the Not In keyword.

To retrieve the ID, name, and DOB of employees with ID in the range 2 to 8 and names other than ‘ADELYN’, ‘FRANK‘, and ‘JULIUS’.

This will be the output of the following:

Using SQL BETWEEN vs <= and >= Operators

The following example shows the MySQL Date Between usage for ranges.

The next example uses >= and <= operators and will display the same value.

However, using just operators will result in fewer rows. Indeed, the SQL Between operator is inclusive, and more than that and less than operators are not.

SQL Between is a best practice and requires less coding as compared to the >= and <= operators. It is more user-friendly and you don't need to specify the column to compare twice.

Note: For a range with max and minimum value, use SQL Between whenever possible. Also, if you are a beginner, looking to start your career in SQL. Check out How to Become SQL Developer?

Using Multiple Between Operators

We can use multiple between operators too. Its syntax is:

By using the aforementioned syntax, we can use several SQL Between operators.

Scenario: Get the name of the employee between the ages of 26 and 30 and the salary between  50 to 65 thousand dollars. 

Output of using Between in MySQL: ADELYN

Over the years, SQL has had a strong position on databases. SQL databases could be progressively phased out to more distributed models in the future, with NoSQL and Hadoop competing for first place.

According to Stack Overflow Developer’s survey, SQL is the second most commonly used programming language, used by 50% of all developers and beaten only by JavaScript – a language twice as old as SQL. Hence, SQL databases have a lot of scope in the future.

If you are wondering how much does a SQL Developer make? According to Glassdoor, the national average salary for a SQL Developer is $88,938 in the United States.
