I've done this before; some databases allow for a UNIQUE specifier in the
query (see your documentation). Alternatively (and more resource & time
consuming), you can store results in a regular PHP array (not a result
resource, etc.) and use array_unique (see php.net/array_unique) to create
an array of only unique values.
Hope this helps!

Subject: [PHP-DB] selecting values from column without repeating
Hello,
I was wondering if it would be possible to select values from a column
(lets say the column "year") so that each value gets retrieved only once...
for example, there are multiple rows in a table - some with '2001' as the
value for the year column, and some with '2000'. Now, what I wanted to do
is list the values of the year so that 2001 shows up only once, and 2000
shows up only once without repeating... is this possible?
thanks.
