How to Find Maximum Values in Rows in SQL
To quickly find the maximum values in a row in SQL, 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.
