Identify special usage of one or more columns

Template create table $table$ ($for columns$ $column$ $type$ $if size$($size$)$end$ $unless _last$,$end$$end$);alter table $table$ add primary key (ID);

Primary key

Notes:

What do we do about the column used as the primary key? Again, simply replacing that value with the column keyword would be ambiguous.

Template create table $table$ ( $for columns$ $column$ $type$ $if size$($size$)$end$ $unless _last$,$end$ $end$ ); alter table $table$ add primary key (ID);
