No. The "yomigana" exists in the application world, not in the
database engine itself. What I was talking about was an idea to add
an extra column to a table.
create table t1 ( kanji text, -- KANJI field yomigana text -- YOMIGANA field
);
The query would be something like:
select kanji from t1 order by yomigana;
--
