SQL Exception: Incorrect Syntax Near "Index"

I have a sql query:

INSERT into ProjectFiles (Id,ProjectId,Index) VALUES (@Id,@ProjectId,@Index)

      

        
        
        
      

    

But when I try to insert an object, it throws an exception:

Incorrect syntax next to "Index". If intended as part of a table hint, the WITH WITH keyword and parenthesis are now required. See SQL Server Books Online for correct syntax

I think this is about Index

because sql has a command Index

. How can I tell sql this is my column?
