MySQL implementation of an iterator

is it a way to implement an iterator in mysql which could return a column as "1/10" "2/10" ... "10/10"

Lets say the form is a/b, as input we have only b. Is it possible to solve this without procedure?

EDIT An example. We have a relation PRINTS (id, work_id, edition_no) and EDITIONS (id, work_id, size, edition_size). For web-interface I am trying to render a select with possible options for prints. Html-options should look like

<option value="1">1/10</option>
<option value="2">2/10</option>

All my select list I render with SQL from database, but in this case I do not see any possibility to get it from database in way I need it. Sql should return 2 columns with option-value and option-text. That i开发者_运维百科s a question.

SQL is all about relations, that is, tables. The natural way would be to create a one-column table with 10 (or however much you want) consecutive numbers, index it by that column, and select enough numbers from there, using order by and limit.

Use the CONCAT function to concatenate strings in MySQL:

SELECT CONCAT('<option value="', p.edition_no, '">', p.edition_no. '/', e.edition_size, '</option>')
  FROM PRINTS p
  JOIN EDITIONS e ON e.work_id = p.work_id
