You are encountering this error because.. you are trying to insert a duplicate value into the Primary key column of the table.... Provide the MetaData of the table... or in that
IF EXISTS statement u can use the statement based on Primary key column... like
If exists(Select * from TableName Where Primarycolumnvalue=@Param).
If that exists statement should not be changed.... then Provide the details of the table so we can help...

In your case if you are trying to insert into SectionId and SectionName like below:

SectionId, SectionName
51, A
51, B
.....

then, SectionId and SectionName fields should not be unique, as you are trying to create a composite primary key as per you query:

SQL

if exists(select * from schoolcampus.dbo.Section_details where SectionId=@sectionid and SectionName=@sectionname)

From the error, I guess that SectionId is the PrimaryKey of Table Section_details.

Your Update statement is correct as you are updating a particular Section after getting it (if it exists).

If it doesn't exist, you need to insert all the details, but you can't insert value to the SecionId as it is the PrimaryKey. That's why it is throwing exception that there is already a Section with Id 51.

SQL

insert into schoolcampus.dbo.Section_details(SectionId,SectionName,className,AcademicYear,Createddatetime,adminid,Medium) values(@sectionid,@sectionname,@classname,@acyear,@datetime,@adminid,@medium)

So, remove the SectionId insertion from this query. And after that it should run without any errors.

SQL

insert into schoolcampus.dbo.Section_details(SectionName,className,AcademicYear,Createddatetime,adminid,Medium) values(@sectionname,@classname,@acyear,@datetime,@adminid,@medium)
