Difference between In and Between Operator


When it comes to relational databases, Structured Query Language (SQL) is the appropriate tool to use in terms of storing and changing data. In and Between keywords are two operators utilized most often in SQL. Although they may seem the same at face value, they serve different functions, and their appropriate usage is the key to flawless inquiry. In this article, we will explore the parameters of each operator, input the right syntax and the functions of each operator, giving you real world examples of how to use them.

Understanding the IN Operator:

IN operator in SQL enables you to augment values in a WHERE clause by multiple entry(s).

This approach is often used to give the query more freedom or not limit it to the minimum number of OR criteria.


The IN operator compares to check if a certain value meets any of the items in a given list.


By using IDs 1, 2, or 3, this query gets all employed for the department's employee list.

Understanding the BETWEEN Operator:

In a WHERE clause, the BETWEEN operator identifies the records that fall within a range of values.

This eliminates the hassle of manually comparing a value with a dozen others or even more.


The VALUE operator helps to find whether a particular value is within a certain range.


Differences Between IN and BETWEEN Operators:

Difference between In and Between Operator

Following are the comparative difference between In and Between Operator in detail.


  • IN operator compares whether a value is in the list of comparator ranges.
  • The BETWEEN operator decides whether the score lies in a certain range.


  • As the IN operator operates with discrete values and few options at a time, it will be a good command line technique.
  • BETWEEN queries has the best performance for ranges in continuous type.


  • Working with large arrays of values is a very problematic challenge when using IN operators.
  • In most cases, the BETWEEN operator is suitable, specifically when the indexed columns are used.


  • A merged list using the "IN" is given with the commas.
  • The BETWEEN operator helps narrow down the desired range by setting a lower and upper boundary and the keyword between.


  • In value-driven operations languages, IN operators greatly simplify searches, and their understanding is thus very much facilitated.
  • The Range operator helps define the BETWEEN operator is helps provide clarity.


The IN and BETWEEN operators find extensive application in various scenarios across database management systems, enabling efficient data retrieval and analysis. Here are some common applications of these operators:

1. Filtering Data based on Specific Criteria:

  • The IN operator is commonly used to filter data against multiple values within a single column. For example, in e-commerce platforms, it can be employed to retrieve products belonging to specific categories selected by the user.
  • The BETWEEN operator filters data within a specified range. In a financial database, it can be applied to extract transactions made within a particular date range.

2. Dynamic Filtering in Queries:

  • Both operators facilitate dynamic filtering, allowing queries to adapt to changing conditions. In reporting applications, they enable users to specify multiple criteria without the need for complex logic.
  • For instance, in a customer management system, the IN operator can be used to filter customers by their status (active, inactive, premium) selected dynamically by the user.

3. Optimizing SQL Queries:

  • The use of IN and BETWEEN operators often leads to optimized SQL queries, which improve performance and reduce execution time.
  • In large-scale databases, these operators help streamline data retrieval processes, enhancing the efficiency of applications that rely on real-time data access.

4. Data Analysis and Reporting:

  • Both operators play a crucial role in data analysis and reporting tasks. They allow analysts to extract subsets of data based on specific criteria, facilitating trend analysis, forecasting, and decision-making.
  • For instance, in a sales reporting application, the BETWEEN operator can be used to generate monthly sales reports by filtering transactions within each month.

5. Dynamic User Interfaces:

  • The IN and BETWEEN operators are often integrated into dynamic user interfaces to provide users with interactive filtering options.
  • Example: An online search engine allows market segmentation because customers can now touch a slider with their cursor and set limits on the product price range. The `BETWEEN' operator within SQL query search filters has an application internally.


  • Basic operators like the IN operator in SQL may impose requirements and lower the number of records that can be included when they fulfill specific conditions or range standards. Between them is one.
  • That's why it is crucial to figure out what makes those operators independent from each other so that you can generate the most profitable search that you can.
  • Developers may enjoy using operators, be disciplined and thoughtful, and be easygoing. They may also be concerned with the effectiveness and clarity of their codes. This can include manipulating and querying data from relational database systems, for example.


  • IN and BETWEEN are both very useful when filtering data based on certain criteria. They allow for various searches in the databases and are extremely handy in data management.
  • The IN operator is able to control the filtering method, which conforms to multiple values within a single query. The less use of many OR statements in this process makes its syntax simple and brings about consistency in the syntax and maintainability of the process. Besides this, the IN operator removes the complexity of filtering and increases the speed of queries when querying for column values that must match with any values of a set/list of values given.
  • On the other hand, the BETWEEN operator is invaluable for filtering data within a specified range. It offers a clear and intuitive syntax for specifying inclusive ranges, reducing the complexity of queries involving numerical or date-based conditions. The BETWEEN operator not only improves code readability but also enhances query performance by utilizing index scans efficiently, particularly when working with indexed columns.


Finally, mastering complex data manipulations with SQL's IN and BETWEEN operators provides programmers with the capability of making precise and effective queries. Therefore, it is an important process in data administration and analytics in relational database systems.

Frequently Asked Questions (FAQs) on the Difference between IN and BETWEEN Operators in SQL

What things do the IN and BETWEEN operators in SQL have in common, and what distinguishes them?

During the formulation of a WHERE clause with multiple values, the IN operator is applicable for comparing whether any value of the list matches the given value.

When declaring a set of values and boundary values, the BETWEEN operator acts as a criterion to determine whether a given value falls within the range.

When should IN be preferred, or the case of how to use it?

When using a filter based on a small scale with few choices, the OR IN condition is welcomed. Values make the queries more understandable, and they also make it easier to understand them. Thus, the use of a declaration of values paves the way to clarifying the intentions of the stakeholders.

In what situations should I apply the operator BETWEEN?

The BETWEEN operator performs better when checking discrepancies against a continuous range of parameters, such as date ranges or numerical intervals. It creates an overview of dot syntax that supports ranges with inclusive stops.

How can we write the IN operator's syntax differently from the BETWEEN operator?

The BETWEEN operator utilizes the term BETWEEN followed by two endpoints, while the IN operator makes a list separated by commas and encloses it in parenthesis.

Because these operators are used in operations, are these have any performance issues?

After all, performance issues are also at the heart of the discussion. A number of values in a list may have a negative impact on the operating velocity, more so when it's an unindexed column. On the other hand, BETWEEN implementation usually holds satisfactory results because it utilizes index scans when performed on indexed columns. As a result, index scans are often preferred when working with indexed columns to ensure satisfactory performance.

Could the operation be amalgamated into one sentence using the BETWEEN and IN operators?

But only if your constraints on the passage through the filters call for it. Take, for example, the BETWEEN operator, which can be used for a specified range, and the IN operator, which can be used for a particular category.

How can the reader write code? Can it provide an operator or another solution?

Whether you want a condition of equality or inequality between the value and the data from your table determines which of these operators you should use. OK, then, if you work with concise figures, the IN operator may brighten things up. On the contrary, the BETWEEN operator can also effectively be employed when ranges are being maintained.

What techniques can I use to optimize responses?

Assert that selected fields (or all important columns) are bound correctly, aiming to accelerate the search using the IN operator on long lists of items. In addition, make sure to use the proper data type and hold off adding redundant values in the IN operator's list of values.

When operating by the IN and BETWEEN operators, what usual rules should be followed?

In fact, there might be particular good practices like we should use BETWEEN instead of IN operator in case of continuous ranges and also other examples like choosing BETWEEN for few discrete values or limited options. Observably, another good maintenance strategy is to write queries that are simple and easy to grasp.

Is the IN or BETWEEN operator an option to get the same result?

The core feature of the operators is their ability to filter out the data efficiently. Even though the operators play a very important role in filtering the data, their functions are quite different from each other. Along with the BETWEEN operator in what they are best for describing ranges inclusively, the IN operator is also suitable to use in matching values against a list of them. Select operators under your unique filtering scope.
