Syntax:-

Select Max (col1) from table_name

In this article, we are going to use the following table for the examples:-

CREATE TABLE [dbo]. [Employee](
[Empid] [Int] IDENTITY (1, 1) NOT NULL Primary key,
[EmpNumber] [nvarchar](50) NOT NULL,
[EmpFirstName] [nvarchar](150) NOT NULL,
[EmpLAStName] [nvarchar](150) NULL,
[EmpEmail] [nvarchar](150) NULL,
[Salary] [int] NULL
)

We insert following data into the above tables:-

Insert Into Employee (EmpNumber,EmpFirstName,EmpLAStName,EmpEmail,salary)
Values('A001','Vivek','Johari','samir@abcmail.com',200000)

Insert Into Employee (EmpNumber,EmpFirstName,EmpLAStName,EmpEmail,salary)
Values('A002','Abhinav','Golwalkar','abhinav@abcmail.com',100000)

Insert Into Employee (EmpNumber,EmpFirstName,EmpLAStName,EmpEmail,salary)
Values('A003','Neha','Sharma','neha@abcmail.com',300000)

Insert Into Employee (EmpNumber,EmpFirstName,EmpLAStName,EmpEmail,salary)
Values('A004','Chandra','Singh','vivek@abcmail.com',320000)

Insert Into Employee (EmpNumber,EmpFirstName,EmpLAStName,EmpEmail,salary)
Values('A005','Avinash', 'Dubey','avinash@abcmail.com',250000)

For example, query to get the maximum salary of an employee from the table Employee is given below:-

Select Max (salary) from Employee

It will gives the following result:-

320000
