    <p>I have a comments section on a website i'd like to streamline a bit if possible so it's not as much of an impact on the database. When a user selects a post, and if it has comments associated with it, it lists the comments. when the comments list, it fetches the username from another table. I store the id for the user in the comments table, and use that id to select the record from the users table. and displays as "user" said:</p> <p>lets say i have 1000 comments on a post, it will hit the users table 1000 times to grab user names. I think this is probably a bad design. i thought of a few solutions, but don't know what would be recommended in this situation. </p> <p>should i just be storing the username inside the comments table?</p> <p>should i store all of the usernames already called in a session array?</p> <p>put all of the usernames in a file, and call from the file?</p> <p>or is there another solution that i haven't thought of?</p> <p>i'm kind of confused. I thought i was doing the right thing by using the IDs in the comment table, and then using it to fetch the username, but after reading about a million posts on using less impact on the database, i'm starting to question myself. </p> <p>WOW, thanks for all of the useful answers. here is the table scheme, i don't know why i didn't put in in originally.</p> <p>comments table for jokes:</p> <pre><code>id | author_id | joke_id | date_created | body ---+-----------+---------+--------------+----- 1 | 3 | 2 | 2011-06-12 | this is a comment </code></pre> <p>and for the users:</p> <pre><code>id | user_name | password | email | date_joined | visible ---+-----------+----------+-------+-------------+--------- 3 | booboo | password | email | todays_date | 1 </code></pre>

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.
