Intersection command in SQL Server

{ query_specification }
 INTERSECT
{ query_specification }

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′,’Amit’,’Kumar’,’amit@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)

Example

Select Empnumber from employee where salary>200000

Select Empnumber from employee where salary between 100000 and 320000

A001
A002
A003
A004
A005

Select Empnumber from employee where salary>200000
 INTERSECT
Select Empnumber from employee where salary between 100000 and 320000
Result
