Checking an input param if not Null and using it in where in SQL Server

Question

What is the best way to include an input param in the WHERE clause but exclude it if it is null?

There are a number of ways I believe, but I can\'t seem

Answer 1

I think this will help

@id 
@name

SELECT [Id],[Name] FROM [Person] 
WHERE Id = @id and ISNULL(@name, Name)

This will allow you just ignore the Name condition if it is null
