    <p>so I have just finished a degree in computing and have just started industry related employment and wow... we really don't seem to learn much at uni, just the bare basics.</p> <p>Anyway, I am learning Apex and attempting to write my first trigger. The online tutorials are pretty unforgiving and I find that they seem to all miss out what my brain is lacking.</p> <p>I am writing a trigger to automatically send an email to a specified address, the sending the email part is fine however I want to send in the email what has been changed and read as to whether it anything has been changed. What I have so far is as follows:</p> <pre><code>trigger Test1 on Account (after update) { if(Trigger.isUpdate) { //Commit current transaction, reserver email capacity Messaging.reserveSingleEmailCapacity(1); //Create an email message object Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage(); List&lt;Messaging.SendEmailResult&gt; results = new list&lt;Messaging.SendEmailResult&gt;(); //hold email address String[] toAddresses = new String[] {'example@example.com'}; //Assign new address string mail.setToAddresses(toAddresses); //specify return ad (assuming as being sent from server) mail.setReplyTo('pwitherby@gmail.com'); //sender name mail.setSenderDisplayName('Mr Apex Tester'); //Subject Specification mail.setSubject('Subjected to Learning'); //And... the content mail.setPlainTextBody('You have just changed sumek... this really what you want....?') if (!results.get(0).isSuccess()) System.debug('That didnt really work did it? Reason: ' + results.get(0).getErrors()[0].getMessage()); } } </code></pre> <p>So my main questions that I cant find an answer for: Will this work at current? so will this send this email if anything in the schema gets altered/updated? I want to put in the email body what has been altered and what it has been changed to i.e "you have changed " + whatsChanged + " to " + telephoneNumber. How do I listen for changes or is it already doing that? Am I writing this to a decent standard or is it just messy code!</p> <p>Sorry to waffle, it is my biggest downfall however I struggle to augment my questions without it! </p>

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.
