    copied!<p>I have a MySQL database that looks similar to this:</p> <pre><code>ID Group Name 1 1 John 2 1 Andrea 3 1 Jack 4 2 Mike 5 2 Kurt 6 3 Alice </code></pre> <p>I need to sort the results in a html table that looks like this:</p> <pre><code>Group Name ----------------------- 1 John Andrea Jack ----------------------- 2 Mike Kurt ----------------------- 3 Alice ----------------------- </code></pre> <p>I don't know if this should be done with a SQL query (concat_group, or something similar) or with PHP, can somebody please help me out?</p> <p>Guys, thanks for the help below, but I also need to accomplish something similar, like this:</p> <pre><code>ID meta_key meta_value name 1 group 1 John 2 group 1 Andrea 3 group 1 Jack 4 group 2 Mike 5 group 2 Kurt 6 group 3 Alice </code></pre> <p>and I need to sort / display the same as the example above, something like this:</p> <pre><code>group name ----------------------- 1 John Andrea Jack ----------------------- 2 Mike Kurt ----------------------- 3 Alice ----------------------- </code></pre> <p>Now my problem has taken new dimensions. My database looks like:</p> <pre><code>b.ID b.meta_key b.meta_value a.title 1 group 1 Title 1 2 group 1 Title 2 3 group 1 Title 3 4 group 2 Title 4 5 group 2 Title 5 6 group 3 Title 6 7 coef 6 Title 1 8 coef 4 Title 2 9 coef 12 Title 3 9 coef 2 Title 4 9 coef 3 Title 5 9 coef 7 Title 6 </code></pre> <p>(I'm working with to tables)</p> <p>And I need to achieve:</p> <pre><code>group title coef --------------------------------- 1 Title 1 6 Title 2 2 Title 3 12 -------------------------------- 2 Title 4 2 Title 5 3 -------------------------------- 3 Title 6 7 -------------------------------- </code></pre> <p>¿Is this even possible?</p>
