Opps. I meant GROUP BY... and it looks like I don't need to include the
COUNT().
SELECT email_addr, x GROUP BY email_addr HAVING x = 1;
Is this the only way to display a listing without duplicates, or is there a
more efficient (faster) way? I don't want to DELETE the duplicates, just
don't

I have a user database where a year has to be put in.
Now, I want to compile a list of each different year and how many users are in that
year.
Is there a way to do this beyond coding for each year:
SELECT * FROM students WHERE year = '1983' ?
- Kath
You could try something like this:
SELECT year, count(studentID) FROM students GROUP BY year
...where studentID is the primary key column/field in your students table.

Can i know the date of the last table update in a Mysql database?
You can add a field named 'modified' that is of type 'timestamp' and use:
select max(modified) from blah;
I don't know of any documented way to check the last modified time for a
whole table.

Is it possible to move through an array that is returned as a recordset
and then move back to the beginning of the array.

reset($array), if this is what you need.
this resets (who would have thought it?) the internal pointer back to the
first
position.

I created a table with FaceMysql that had one field and I could not add data
to it .Only when I recreated it with 2 fields and a primary key did it
work.Is there any reason for this?Must there always be a primary key in
Mysql?I've never known this to be true of relational Db's.Especially if you
mysql use myisamchk and myisamchk --recover to check and repair the table.
However, does anybody know how myisamchk indicates that whether the table is
damaged or
whether the the repair is successful when running myisamchk or
myisamchk --recover command?
