If Exists then Update else Insert in SQL Server

In this blog I'll tell you about how to check and then select whether to update or insert.

Introduction

 

In this blog I'll tell you about how to check and then select whether to update or insert in table in SQL Server.

 

I am providing an example by which you can achieve this:

if exists(SELECT * from Student where FirstName='Akhil' and LastName='Mittal')
BEGIN
 update Student set FirstName='Anu' where FirstName='Akhil'
End
else
begin
insert into Student values(1,'Akhil','Mittal',28,'Male',2006,'Noida','Tenth','LFS','Delhi')
end

 Here I am checking for the Name and First Name of a person and if it exists it will replace it else insert it.
