    <p>sorry for bothering you again but I'm really stuck!</p> <p>How would it be possible to do an if statement referencing wherever or not data was from a certain column or to strip the last number in a column's name and reference it that way?</p> <p>Basically I have an musicians database, where a person from the PEOPLE table is linked via ID to instruments in the INSTRUMENTS table, I have an e-mail search function that I need to send out the relative data to the relative instruments. So if someone plays guitar as their 2nd instrument and someone else plays it as their 5th I need the relevant grade, standard and comments to get sent with them in the e-mail function.</p> <p>I want to get the comments[i] , grade[i], standard[i] of the matching instrument[i]</p> <p>My tables layout: ( I know it isn';t very efficient and I will look into DB normalization in the future!)</p> <hr> <p>TABLE:<strong>INSTRUMENTS</strong></p> <p>COLUMNS:</p> <pre><code> id instrument1 grade2 standard3 comments4 instrument2 grade2 standard2 comments2 instrument3 grade3 standard3 comments3 instrument4 grade4 standard4 comments4 instrument5 grade5 standard5 comments5 </code></pre> <p>TABLE: <strong>PEOPLE</strong></p> <p>COLUMNS:</p> <pre><code>id first last snumber course email graduate inumber </code></pre> <hr> <p>EDIT:</p> <blockquote> <pre><code> while($getresults = mysql_fetch_assoc($result)){ </code></pre> </blockquote> <pre><code> $peoplequery = "SELECT * FROM people WHERE id = {$getresults [id]}"; $peopleresults = @mysql_query($peoplequery); $getpeopleresults = mysql_fetch_assoc($peopleresults); //add the details returned by the database to the table: $table .= " &lt;td&gt;&lt;p&gt;{$getpeopleresults [first]} {$getpeopleresults [last]}&lt;/p&gt;&lt;/td&gt; &lt;td&gt;&lt;p&gt;{$getpeopleresults [email]}&lt;/p&gt;&lt;/td&gt; &lt;td&gt;&lt;p&gt;{$getpeopleresults [course]}&lt;/p&gt;&lt;/td&gt; &lt;td&gt;&lt;p&gt;{$getresults [grade]}&lt;/p&gt;&lt;/td&gt; &lt;td&gt;&lt;p&gt;{$getresults [standard]}&lt;/p&gt;&lt;/td&gt; &lt;td&gt;&lt;p&gt;{$getresults [comments]}&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td colspan=8&gt;&lt;hr size=1 color=gray&gt;&lt;/td&gt;&lt;/tr&gt; } "; } </code></pre>

    1. COYou are right: it'll be easier to fix the DB design once the app is finished :-P

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
