SQL SERVER MAX: Display the Maximum Number in Column

Functions are keywords in SQL used to manipulate values in database for output purposes. A function is a command normally used together with a column name that processes the data to produce an output. SQL contains several types of functions. SQL Aggregate functions can perform useful functions such as COUNT, SUM, AVG, MAX, MIN.

SQL Max is used to find the maximum value in a certain column in a table. In my example, I have the SALES table below with records.

Syntax SQL MAX

select MAX(column_name) from table_name

SALES Table

To display 60.00 which is the maximum amount found in the total column, you need the following SQL Max function.

Syntax SQL MAX

select MAX(total) from sales
