Re: Versioning Schema SQL ideas needed

create table templates(
   template_id int not null primary key,
   template_groupid int not null,
   template_version int not null
   template_text text not null);

Would I need to resort to using a CTE or subquery to make this sort of
thing work ?  I can't seem to make it work with group by since group
by expects aggregation. Surely I don't need to normalise it into a
couple of tables ?
