Apex Trigger Practice (3) – Trigger on Attachments to count the number of attachments

Question Hints:

Account is standard object and attachment is child object.


We need to create an Apex Trigger on Attachments to count the number of attachments on the object – let’s take Account – and store in number field “Number of attachments”.

Trigger is considering all the possible scenarios in this – after insert, after update, after delete, after undelete.

Implementation Verification:

Upload your code in Github and provide the link of public repo in comment below, it will be reviewed based on availability and feedback will be shared.

P.S: Be honest, watch the clock to check your efficiency. Happy coding.
