Vahan4033 on "Add new column in "posts" table?"

Hi I want to add new custom column to post table and display wordpress loop sorted by that column. Is it possible or not.... will wordpress work normally or I have to do additional changes in core?

Now I do that but values of that column with post ids are kept in separate table (I wrote custom query to db) but I have performance issues it runs 10 times slow than wordpress loop does.

I want to have very fast execution because blog has growing content and it will have about 100 000 articles in near time. I don't want to use post meta table.

Any advises?

Thanks!
