PHP - Select Field Question

Can anybody clarify the usefulness of "AS" and elaborate on how it operates.

If I select a 'bananas' AS 'yeelow fruit' will it change the TITLE in the table?  Or the table that is being viewed?
If I dump a list of 'FRUITS' into and HTML table, will using AS rename each column for me, or is that handled by MY coing of the HTML table?

Hello.

I am trying to display only one instance of records that have the same memberid in my db. I am using the following statement but it continues to show all of the records that have the same memberid. Any ideas what I may be doing wrong?

Code: [Select]
$sql = "select DISTINCT memberid, event, category, date, enddate, locality, location, address, city, state, zip, contact, phone, notes, doc1, doc2, doc3, doc4, doc5 from event where date >= '$datenow' ORDER by date ASC";
Thanks for any help!

Hi Guys,

Can someone please help me before I kill myself!

I have a table holding details of images to be displayed in a gallery.
The table has columns as 'id', 'image_caption', 'file_path', and 'userid'.

The 'id' column is the unique key, and the 'userid' column is obviously id of the user who uploaded the image.

What I would like to do is select and display one image from each unique userid and then display each image along with the details in my gallery. It doesn't really matter which users image is selected aslong as there is only one for each unique user.

I have been trying a number of ways to do this (DISTINCT / subqueries) but I just cant get anything to work.
Could someone please advise me on how I could get this to work.

Cheers in advance.

I want to select the user from super_administrators, administrators, teachers and students, and give the user permission based from what table he "came". But is giving the "Query failed" error...
