Row Rank in a MySQL View

Question

I need to create a view that automatically adds virtual row number in the result. the graph here is totally random all that I want to achieve is the last column to be create

Answer 1

Oracle has a rowid pseudo-column. In MySQL, you might have to go ugly:

SELECT id,
       variety,
       1 + (SELECT COUNT(*) FROM tbl WHERE t.id < id) as num
  FROM tbl

This query is off the top of my head and untested, so take it with a grain of salt. Also, it assumes that you want to number the rows according to some sort criteria (id in this case), rather than the arbitrary numbering shown in the question.
