IN Operator in SQL
The IN operator allows you to specify multiple values in a WHERE clause.

Syntax :- 
  

SELECT column_name(s) FROM table_name WHERE column_name IN (value1,value2,...)

CREATE TABLE tblStudentRecord
(
Name varchar(100), Rollno int primary key, Branch varchar(30),Email varchar(100),Address varchar(200)
)


Insert some records :-

INSERT INTO tblStudentRecord VALUES('Santosh kumar singh',1001,'Information Technology','sa@gmail.com','A-3033')
INSERT INTO tblStudentRecord VALUES('Er. Reena Tanti',1002,'ECE','err@gmail.com','T-387, Gaya')
INSERT INTO tblStudentRecord VALUES('Chandan kumar',1003,'CSE','chn@gmail.com','Gaya')
