How to Group by Year in SQL

How to Group by Year in SQL

Are you looking for a way to group your data by year in SQL? You've come to the right place! Grouping by year in SQL is a great way to get a better understanding of your data and to make more informed decisions. In this post, we'll take a look at how to group by year in SQL and provide some examples to help you get started.

The Solution

The solution is to use the GROUP BY clause. This clause allows you to group your data by a particular column or set of columns. For example, if you wanted to group your data by year, you would use the following query:

SELECT * FROM table_name GROUP BY YEAR(date_column);

This query will group your data by the year of the date column specified. For example, if you have a table with a date column, the query above will group your data by the year of the date column.

Examples

Let's look at a few examples of how this function can be used. Suppose you have a table called sales with the following data:

date       sales
----------------
2020-01-01 100
2020-02-01 200
2020-03-01 300
2021-01-01 400
2021-02-01 500
2021-03-01 600

If you wanted to group the data by year, you would use the following query:

SELECT * FROM sales GROUP BY YEAR(date);

This query would return the following results:

2020-01-01 100
2021-01-01 400

Additional Info

The GROUP BY clause is supported by most major databases, including MySQL, PostgreSQL, and SQL Server. However, the syntax may vary slightly depending on the database you are using. For more information, check out the documentation for your particular database. 🤓
