Make query like this see data inserted or not by message

SQL

If NOT Exists (Select ProductName From dbo.tblProduct WHERE ProductName = @ProductName)
 begin Insert into tblProduct
( ProductName , ProductCode ) Values ( @ProductName , @ProductCode )
Select 'Data Inserted Successfully' end
else
Select 'Data already exists'

For 1 and 2:

in C#

C#

int rowCount = cmd.ExecuteNonQuery()
if rowCount >0 
{
Record is inserted
}
else
{
	Record already exist.
}

For 3:

SQL

Declare @Error VARCHAR(1000) output
Begin Try
Begin Transaction
IF (@Mode='Insert')
Begin
If NOT Exists (Select ProductName From dbo.tblProduct WHERE ProductName = @ProductName) 
Insert into tblProduct
(
ProductName ,
ProductCode )
Values
(
 
@ProductName ,
@ProductCode )
Commit

End Try

Begin Catch
SET @Error=(SELECT ERROR_MESSAGE())
ROLLBACK TRANSACTION
RAISERROR(@Error,16,1)
End Catch
