-Challenge 1
-'''''''''''
-
-Due to the limitations of MySQL, reserved column names can't be further concatenated. Assume you want to display an image:
-
-::
-
-    # This is valid:
-    10.sql = SELECT concat("/static/directory/", p.foto) AS _img FROM person AS p WHERE ...
-
-    # Returns:
-    <img src=...>
-
-..
-
-
-
-Now assume you want to wrap the image in a div tag:
-
-::
-
-
-    # This is valid:
-    10.sql = SELECT "<div>", CONCAT("/static/directory/", p.foto) AS _img, "</div>" FROM person AS p WHERE ...
-
-    # Returns:
-    <div><img src=...></div>
-
-..
-
-
-
-The example above works fine - however, as soon as you want to use *field wrappers*, things get messy:
-
-::
-
-
-    # This is valid:
-    10.sql = SELECT "<div>", CONCAT("/static/directory/", p.foto) AS _img, "</div>" FROM person AS p WHERE ...
-    10.fbeg = <td>
-    10.fend = </td>
-
-    # Returns:
-    <td><div></td><td><img src=...></td><td></div></td>
-
-..
-
-
-
-To achieve the desired result, one might want to try something like this:
-
-::
-
-
-    # This is NOT valid:
-    10.sql = SELECT CONCAT("<div>", concat("/static/directory/", p.foto) AS _img, "</div>") FROM person AS p WHERE ...
-    10.fbeg = <td>
-    10.fend = </td>
-
-    # Returns a MySQL error because nesting concat() -functions is not allowed
-
-..
-
-
-
-Challenge 2
-'''''''''''
-
-Assume you have multiple columns with reserved names in the same query and want to use one of them in a later query:
-
-::
-
-
-    10.sql = SELECT CONCAT("/static/directory/", g.picture) AS _img, CONCAT("/static/preview/", g.thumbnail) AS _img FROM gallery AS g WHERE ...
-
-    20.sql = SELECT "{{10.img}}", d.text FROM description AS d ...
-
-..
-
-
-
-The example above will fail because there are two img columns which can not be distinguished.
-
-Solution
-''''''''
-
-The reserved column 'F'(=Format) can be used to
-
-*   further wrap columns with a reserved name
-
-*   assign an arbitrary name to a column built through a reserved name to make it accessible in later queries.
-
-Solution for *#Challenge_1*:
-
-::
-
-
-    10.sql = SELECT CONCAT("Q:img|T:div") AS wrappedImg FROM person AS p WHERE ...
-    10.fbeg = <td>
-    10.fend = </td>
-
-    # Returns:
-    <td><div><img src=...></div></td>
-
-..
-
-
-
-Solution for *#Challenge_2*:
-
-::
-
-
-    10.sql = SELECT CONCAT("Q:img|V:mypic") AS wrappedImg FROM person AS p WHERE ...
-
-    20.sql = SELECT "{{10.mypic}}" ...
