[PHP] MySQL select matching
I may be going at this completely wrong but at the moment I'm stuck. I have a DB from a client and need to do several searches on it. This one sentence is important because it's their DB, not mine. So I can't modify the way the DB was created in the first place, I can only work with what I have. And, whatever the solution to this might be, it does NOT have to be strictly MySQL, it can also be a PHP solution (which is why I'm sending it there as well.) So, having said that, consider the following table: +---+-+-+---+ | 1 | 123 | 0.0 | C | | 1 | 234 | 0.1 | D | | 1 | 345 | 0.0 | D | | 1 | 456 | 0.1 | C | | 1 | 567 | 0.1 | G | | 2 | 123 | 0.0 | C | | 2 | 234 | 0.1 | D | | 2 | 345 | 0.0 | D | | 3 | 234 | 0.1 | D | | 3 | 345 | 0.0 | D | | 3 | 123 | 0.0 | C | | 3 | 456 | 0.1 | C | | 3 | 567 | 0.1 | G | | 4 | 123 | 0.0 | C | | 4 | 234 | 0.1 | D | | 4 | 345 | 0.0 | D | +---+-+-+---+ mysql select * from table where id='1'; +---+-+-+---+ | 1 | 123 | 0.0 | C | | 1 | 234 | 0.1 | D | | 1 | 345 | 0.0 | D | | 1 | 456 | 0.1 | C | | 1 | 567 | 0.1 | G | +---+-+-+---+ Now, I have to find other IDs that match the above result. In the table, that would be ID '3' (and in the entire DB, there may be others as well - I need to find all those IDs.) But, notice how ID 0003 isn't in the same order as ID 1, but the data is still the same. So how do I efficiently search through the DB to find other IDs that matches the one I need? I can't imagine doing a for loop selecting each ID and comparing their result to the one I'm starting with. If the DB contains thousands upon thousands of rows, that might take a very long time.

As administrators, my coworkers and I need to be able to filter orders by

View all orders for Jack and the Beanstalk, where an order may have Jack

I have an order table that keeps track of the order_id, the date, the

the order. This has a one-to-many structure (without foreign keys because
it is mysql).
I was baffled as to how to filter the orders by the item_id that appears
in the order_lineitem table.
I just came up with this, but I'm not sure how the mysql_queries will
handle an array. Do I have to do some extensive regular expression
management here to get this to work, or will it accept an array?
?php
if (isset($_POST['showid']))
$showid = $_POST['showid'];

$subResult = mysql_query($subSQL);

$extQuery = 'order_id = {$subResult}';
}
$resultOrders = mysql_query(SELECT * FROM afy_order {$where}
{$extQuery};) or die(mysql_error(Could not query the database!));
?
If $_POST['showid'] is likely to be an array, use implode to create a comma
separated string of values, then use IN to build the query.
$ids = implode(',', $_POST['showid'];
$subSQL = SELECT order_id FROM afy_show_lineitem WHERE show_id IN ($ids)
But you need also to check your logic - your query above will have two WHERE
in it and will fail miserably :-) And your call to mysql_error will
probably not help you either, as the (optional) argument should be a link
identifier, not a string of your choosing.

$subResult is a resource. You need to fetch the results
before you can use them like this. Maybe something like:
/* UNTESTED */
/* Don't forget to escape! Some will argue that
you are better off using prepared statements. */
$showid = mysql_real_escape_string ($_POST['showid']);
$q = _
SELECT `order_id` FROM `afy_show_lineitem`
WHERE `show_id` = '$showid';
_;
$res = mysql_query ($q);
if ($res) {
while ($row = mysql_fetch_row ($res)) {
$ids[] = $row[0]; /* Assuming numerical ids. */
}
$ids_spec = implode (',', $ids);
mysql_free_result ($res);
} else {
/* Handle error */
}
if (isset ($ids_spec)) {
$q = _
SELECT * FROM `afy_order`
WHERE `order_id` IN ($ids_spec)
_;
$res = mysql_query ($q);
if ($res) {
/* Do stuff */
} else {
/* Handle error */
}
}
But you could also do it in one query (*untested*):
/* UNTESTED */
SELECT `ao`.* FROM `afy_order` AS `ao`,
`afy_show_lineitem` AS `asl`
WHERE `ao`.`show_id` = $show_id
AND `asl`.`order_id` = `ao`.`show_id`
Or maybe there are better ways, such as using INNER JOIN,
but those sometimes end up using a temporary table...

[PHP] mysql select and date functions
i have a field in a table called Posted and it is a timestamp type
im using mysql and my page is supposed to take the timestamp field and show
it on the screen in the form of month#/dayofmonth/year
like 02/18/2003 the problem im having is trying to get it to be formatted..
i tried mysql functions like dayofmonth(Posted) month(Posted) and
year(Posted) in the query:
$query=mysql_query(select dayofmonth(Posted), month(Posted), year(Posted),
hour(Posted), minute(Posted), Name, Prayer from prayer);
this query works just fine but my question is now in php how to display the
results for dayofmonth(Posted) and so on further code follows:
while($view=mysql_fetch_array($query)) {
//display variables from query here...
//get to the date functions:
//$view[month(Posted)]/... doesnt work
//php complains about missing ] and this doesnt work
//either
while($view=mysql_fetch_object($query)){
//show variables here..
//show date fields in table...
//$view-dayofmonth(Posted) doesnt work either all i get
//in display is (Posted)
...rest of code here...
?
and its strange because if i try: echo $view-dayofmonth(Posted); i get
parse error call to undefined function dayofmonth() in file.php on line
(line #)
any ideas on how to get this to work?

Try:
$sql=SELECT * FROM divx WHERE .$sql1..$sql2. ORDER BY
titulo;
and add a space after the WHERE.
Also consider the positioning of the single quotes (') and double-quotes ()
in the $sql1 assignment statement - they must be nested.

What happens if $sql1 or $sql2 are empty (as your example provisons)? Create an $sql3 that combines $sql1 and $sql2, and construct your SQL accordingly: $sql1 = ($titulotxt ? null : titulo like '%$titulotxt%'); $sql2 = ($cdstxt? null : cds like '$cdstxt'); $sql3 = $sql1 . ($sql1 $sql2 ? ' AND ' : null) . $sql2; $sql = 'SELECT * FROM divx ' . ($sql3 ? WHERE $sql3 : null) . 'ORDER BY titulo'; -- O Ernest E.

For example:
$query=mysql_query(SELECT username FROM users,$db);
while ($row=mysql_fetch_array($query)) {

And B. van Ouwerkerk is right with his suggestion about manuals and

But anyway I hope it helps

Because you can also do:

do {

} else {
echo no records found!;

Re: [PHP] MySQL Select
Hi
This is what I always do...
1. for one row (saved in array $reihe)...
$bla = SELECT * FROM table WHERE id = '$something''';
// db is your database connection
$test = mysql_query($bla, $db);
// you dont have to use the if...i do that to check if anything
was returned
if ($reihe = mysql_fetch_row($test))
{
echo $reihe[0] . $reihe[1];
}
//this will output field one and two of the queried row
2. to get several rows in an array:
$bla = SELECT * FROM table''';
// db is your database connection
$test = mysql_query($bla, $db);
while ($reihe = mysql_fetch_array($test))
{
echo $reihe[0];
}
//this will output the first field of all rows in this table

[PHP] MySQL select rand() with weighting?
Hi Guys, Does anyone know how to select one field randomnly from a MySQL table against a weighting column in the same row the field is selected from? For example, SELECT id, url, image FROM table ORDER BY rand() LIMIT 1. And have a column like weighting where values between 1 and 100 are held - The larger values making it more likely that they're going to get pulled out. So say I have three rows in the table, one weighing 100, the others weighing 50, the one weighhing 100 stands a better chance of being selected randomnly? I know I've not explained this too well, but hopefully *someone* will know what I'm rambling on about ;) Thanks as always, James. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

[PHP] mySQL - select column
Hi all,
Given that the resultset from a mysql query is a 2-d array (of sorts - I
don't know), if I retrieve only a single column, is there an easy way to
grab it as a linear array? For example - old way:
$uids=array();
$res = mysql_db_query("db", 'select uid from tbl;', $link);
while ($row = mysql_fetch_row($res)) {
array_push ($uids, $row[0]);
}
It seems a little redundant to make another array if one already exists. The
end idea is to get to a list of uids ($uid_str = join(',',$uids)) that can
be used in a second query to the db (to make up for the lack of subqueries
in mysql). I guess what I'm asking - can you do a join on the mysql
resultset array somehow. I know in the perl DBI you can get a column of
results, but can't find it in php.
Thx.

Re: [PHP] MySQL SELECT performance suggestions
You don't need to select all the data to get the number of rows. Try
this:
select count(*) as total from products where $product_query;
Then use total instead of num_rows.
Be sure the elements in your where clause are properly indexed.
[EMAIL PROTECTED] wrote:
Could someone suggest some options here for performance improvement?
I have a table with about 300,000 entries/records by 7 columns/fields. All of
the information varies from entry, but only one field can be declared as UNIQUE.
I have PHP perform SELECT queries on the table, and I need to display the
results in a format of: "viewing $top to ($top+$depth) of $numrows found"
I haven't found a way to determine $numrows without performing a second SELECT
in this format:
$numrows = mysql_num_rows (db_query("SELECT * FROM products WHERE
$product_query"));
if ( $numrows $depth ) { $depth = $numrows; }
$qid = db_query("SELECT * FROM products WHERE $product_query LIMIT $top,
$depth");
So, this takes about twice as long as it would without figuring the $numrows.
Does anyone have any suggestions as far as what can be done to speed this up?
Assume that the table in question is optimized with indexing and UNIQUE values.
Thanks.
