How to Find Most Frequent Value in Column in SQL?

In SQL, sometimes we need to find frequent values in a column.

Finding the Most Frequent Value in a Column in SQL

Here, we will see an example of how to find the most frequent value in a column in SQL.

First, let's create a database and demo table.

CREATE DATABASE GFG;

USE GFG;

CREATE TABLE GetRepeatedValue (
    Value INT
);

INSERT INTO GetRepeatedValue 
VALUES
    (2),
    (3),
    (4),
    (5),
    (6),
    (4),
    (6),
    (9),
    (6),
    (8);

SQL query to select the most repeated value in the column

Count each value using the COUNT() function SQL. Then sort those values in descending order using ORDER BY clause. Get the most repeated by selecting the top 1 row with SELECT TOP 1 clause.

Query:

SELECT 
    TOP 1 
    Value, 
    COUNT(Value) AS count_value
FROM 
    GetRepeatedValue
GROUP BY 
    Value
ORDER BY 
    count_value DESC;

Output:

Explanation: Upon executing the above query, you'll find that in the GetRepeatedValue table, the most repeated value in the Value column is 6.
