How to Find the Maximum Value of a Numeric Column in SQL

Finding the Maximum Value of a Numeric Column in SQL

Are you looking for the maximum value of a numeric column in your database? If so, you're in luck! SQL has a handy way of finding the maximum value of a numeric column that can help you get the answer you need.

The Solution

The solution is to use the MAX() function. This function takes a single argument, which is the column you want to find the maximum value of. For example, if you wanted to find the maximum value in the age column of your database, you would use the following query:

SELECT MAX(age) FROM table_name;

Examples

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

name      age
----------------
John      25
Jane      30
John      25
Bob       20

If you wanted to find the maximum age in this table, you would use the following query:

SELECT MAX(age) FROM users;

This query would return the result 30, since that is the maximum age in the table.

Additional Info

The MAX() function 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. 🤓
