RES: SQL Select Idea [ORDER BY]
Hi Michael, Using two select's we already solved the problem. The challenge is to make the same thing using just one select. I need to know if is there an way to get the last date or the 10th index to make the WHERE part. Like the LAST_INDEX() function, that gets the last AUTO_INCREMENT...but I just saw apllacation using the update command. Well, any new ideas? Best Regards, Felipe -Mensagem original- De: Michael T.

Hi Michael, The ten last dates appear as a default result of a Archives page. When I enter for the first time in the page, it give me the last ten Files that was uploaded. In the same page, I can ORDER BY the ten last dates results by COD, DATE, NAME or FILE. So, when I click in some os then, I need to ORDER the TEN DATES, not the entire table and give ten results, did you get it? Any idea? Regards, Felipe -Mensagem original- De: Michael T.

RES: SQL Select Idea [ORDER BY]
Well, could you explain the behave of ORDER BY DATE,COD? I will show you bellow what I want, graphically: 1) What I have: Table: processo_arquivos _ |Cod| Date | - |1 | 12/10 | - |2 | 13/10 | - |3 | 14/10 | - |4 | 15/10 | - |5 | 16/10 | - 2) What I get if I use the: SELECT * FROM processo_arquivos ORDER BY DATE DESC LIMIT 0,3 (considering that I only want 3) _ |Cod| Date | - |5 | 16/10 | - |4 | 15/10 | - |3 | 14/10 | - 3) The problem getting the result like this: Since I have a link in the header of the tabel that make the ORDER BY work, when I select de COD after the result above, I should get: PS: When I select the COD (order by COD) it sends the ORDER BY value to the same select above. _ |Cod (link) | Date | - |3 | 14/10 | - |4 | 15/10 | - |5 | 16/10 | - but instead of the above I get: _ |Cod| Date | - |1 | 12/10 | - |2 | 13/10 | - |3 | 14/10 | - So, the problem is when I select a new ORDER BY I make the query in the entire Table. What I want is to make the query only in the matched results. I have a php page that starts with a default search (the ten dates). So, what I really need ia an way to make a select without any data from the DB. I tried to use de LAST_INDEX() function to do this but I didn't go anywhere.

RES: RES: SQL Select Idea
Hi Michael,
Well, the SQL Query you requested is exatcly the one I'm asking! :-)
Like I said in other message, I solved the problem using TWO queries. In
the first one I get the 10th date. In the second one I use this date to
LIMIT the result to what I want. But is not a question of solving the
problem, but a question for a better designed query. I just want to use 1
(one) select to do the same thing that the two selects above do, if it is
possible of course. Below, I will show you the actual scenary, and after,
the question, how can I optimize it to use just one select?. If I can get
the value of the LAST index, I can subtract 10 indexes from this value and
get only this range of values, doing this I will get the last ten dates
without the LIMIT 0,10 that don't give me what I want.
Actual scenary:
// This is the main select that give me the last ten dates.
$sql = select pa.codigo,arquivo,label,tipo,DATE_FORMAT(data,'%d/%m/%Y -
%H:%i') as ndata,RS,ref_wicie from processo_arquivos as pa,cliente as
c,processo as p where pa.codigocliente=c.codigo and
pa.codigoprocesso=p.codigo ;
// This is the FIRST select that catch the LIMIT date
$sql2 = select data from processo_arquivos as pa,cliente as c,processo as
p where pa.codigocliente=c.codigo and pa.codigoprocesso=p.codigo order by
data desc limit 0,11;
$conexao-Query($sql2,$this-banco,$this-valor);
$i = 0;
if ($conexao-Select($this-banco)){
while (($this-valor =
mysql_fetch_array($this-banco)) ($i10)){
$i++;
}
$dataLimite = $this-valor['data'];
$sql .= and data'.$dataLimite.' ; --- Here I
select the last
ten dates.
}
What I wanted:
--- ???
Just do what I'm doing above using only ONE select.
Any tips?
Best Regards,
Felipe

SQL Select Idea
Hi List Users, I want to know if anyone has any idea on how can I do the SQL command below to archive a result. I have one table called processo_arquivos that have a filed called DATE and another FIELD called COD (primary key). I want to select the last TEN (10) dates from the Database, but only the last TEN. How Can I do this? Any ideia? I tried the sql bellow o archive this, but I was unable to do it. I just want to do this with ONLY one select, not with two. Thanks for any idea.
