select value from tableName where date in (select max(date) from
tableName where id = 4);
But, it doesn't work with mysql 4.0.
Any ideas? Does anybody had this problem before?
What about:
SELECT value, date
FROM tablename
WHERE id = 4
ORDER BY date ASC
Just pick the first row.

Hi, I have a table full of logged urls and ip addresses. The following
query returns all the urls and the number of requests. How would I
modify it to return unique requests based on distinct ip addresses?

when Creating the follow table

With a join and group by I think you have HAVING.
Hi all
how to do this in MySQL? Returning only records with COUNT 5?
SELECT
`groups`.`groupsDescr`,
`roles`.`roles_Agroup`,
`roles`.`rolesDescr`,
COUNT(`roles`.`rolesDescr`) AS TOTAL
FROM
`roles`
INNER JOIN `groups_roles` ON
Do you have separate indexes on:
Table1.ID
Table2.ID
Table1.Field1
Table2.Field1
Table1.Field1
Table1.Field2
Select*
FROM Table1 as a
INNER JOIN Table2 as b ON (a.ID = b.ID or (a.Field1 = b.Field1 and
a.Field2 = b.Field2))
WHERE bla bla bla
We have
to go.
I'll try this, though.

Guess you could use the rand() function and look for a matching row id!?!
Is it possible to randomly select from all entries in a table, but have it
be 2 different ones each time? If so, what documentation should I be
looking
at?
I am using PHP and MySQL together, if this helps.

I used to program for a medical tester.
I used method 2:

results(#assessment_nr, labtest_nr, p, d) where p and d are my two
results.
The BIG advantage was changes to the tests, adding new ones, or deleting
fields. Made it much more flexible.
Yes it is a myth.
The records will come back in the same order IF there have been not
inserts and deletes. Depends on the database product to.
My boss says that if you do a select statement against a table the
result set always comes back in the same order. I say that this is a
myth and

How about: (I reversed on set of quotes)

Err...what I meant to say here was ascii code equivalent (chr(39) (I
tried single *and* double quotes). Sorry about that.

Serves me right to type this stuff instead of copying/pasting - my

I believe you have to add your AVG() to your GROUP BY clause.

ES.DB_ESTABLISHMENT_ID=GR.DB_ESTABLISHMENT_ID
WHERE
In Oracle you can reference the second field AVG() by the field #.
ORDER BY 2
Thanks a lot for the replies. I have changed the query as follows:

AVG(DB_GRADE)
