[PHP-DB] LIMIT
Is there a way to get the number of rows that would have been returned had there not been a LIMIT clause in a SELECT statement? For example, if Query #1) SELECT * FROM aTable would normally return 100 rows. But Query #2) SELECT * FROM aTable LIMIT 5 will return 5 rows. Is there a way to find out that 100 rows would have been returned if there was no LIMIT clause, by using only Query #2 and maybe a PHP function on the $result?

Re: [PHP-DB] Count Many Records
Thanks for your help, Chris. You certainly got me going in the right
direction. In case anyone is interested, below is the completed
solution, with design elements, turned into a function so I can
easily call it several times.
function counter_maker ($database,$name,$link)
{
echo "";
echo "\"content\">$name";
$query = "select status, count(id) AS count from $database where
status in ('', 'h', 'p') group by status";
$result = mysql_query($query);
while($row = mysql_fetch_assoc($result))
{
$status_code = $row['status'];
if ($status_code == "")
{ $status_code = "n"; }
$count_array[$status_code] = $row['count'];
}
echo " { echo " style=\"background-color: #F3CF45; color: #00599E; font-
weight: bold;\">";
echo $count_array['n']; }
else
{ echo "> 0";}
echo "";
echo " { echo " style=\"background-color: #00599E; color: #F3CF45; font-
weight: bold;\">";
echo $count_array['h']; }
else
{ echo "> 0";}
echo "";
echo "";
if (isset($count_array['p']))
{ echo $count_array['p']; }
else
{ echo "0"; }
echo "";
}
counter_maker ("data1","Form Name","link.php");

Actually the design is in the code below I need to display the
counts from all of those queries in a grid. Basically, its just a
summary of a bunch of information. Another way to look at it would
be a several lines that say something like this:
You have $data1_count NEW records in data1,
You have $data1p_count PROCESSED records in data1,
etc.
Instead of
$data1_query = "select id from data1 WHERE status = ''";
$data1_results = mysql_query($data1_query);
$data1_count = mysql_num_rows($data1_results);
$data1p_query = "select id from data1 WHERE status = 'p'";
$data1p_results = mysql_query($data1p_query);
$data1p_count = mysql_num_rows($data1p_results);
$data1h_query = "select id from data1 WHERE status = 'h'";
$data1h_results = mysql_query($data1h_query);
$data1h_count = mysql_num_rows($data1h_results);
You could do it all in one query:
$query = "select status, count(id) AS count from data1 where status
in ('', 'p', 'h') group by status";
$result = mysql_query($query);
while($row = mysql_fetch_assoc($result)) {
echo "status: " . $row['status'] . "";
echo "count: " . $row['count'] . "";
}

RE: [PHP-DB] mysqldump via php
why no use phpmyadmin to admin the db? Bastien From: Jeffrey <[EMAIL PROTECTED]> To: PHP DB Subject: [PHP-DB] mysqldump via php Date: Thu, 29 Jun 2006 12:38:51 +0200 I would like to do a backup of an entire MySQL database via php.

However... $query="mysqldump $dbase"; $result=mysql_query($query) or die(mysql_error()); ...immediately results in an "error in your SQL syntax near mysqldump [database name]". The reason I want to do a MySQL back up via php is that I have a web application in which the user can archive a project, which involves moving a lot data from one set of tables to another set of tables.

Although there are lots of "Are you sure you really want to do this?" messages the user must click upon, I am sure I will eventually get a user telling me she accidentally archived/deleted stuff and can I help.
