SQLDB works with named parameters.
Parameters must be written in the format :ParamName, not with question marks.

So for your example:

insert into relation
      ( relationid , name )
      ( :id, :name)

:ID and :Name are the parameters.

See for example
There is also an explanation on the wiki.

Thanks Michael,
I will change my code, code used to work in the past but I apparantly missed this change when switching to newer Lazarus version lately.
With an apology for the extra work.
