Working on a script to pull some customer order data from various databases and combine them into one output. Most of the stuff works fine, but can't seem to be able to get the sku's for the products of an order.
Noticed there was a meta_key called "_sku" so tried with something like
$sqlMetaSku = "SELECT * FROM wp_postmeta WHERE meta_key='_sku' AND post_id='$post_id'";
$resultMetaSku = $conn->query($sqlMetaSku);
if ($resultMetaSku->num_rows > 0) {
while($rowMetaSku = $resultMetaSku->fetch_assoc()) {echo($sqlMetaSku);
$clientSku = $rowMetaSku["meta_value"];
echo (between ('s:8:', ';s:12', $clientSku));
}
}
but no luck here.
Noticed there was a key called "_order_key" so maybe that's the way to go? I am not sure how to proceed.

I have two tables:
cache and main
In cache there are a lot of fields; in main a little less. A UNION is not going to work because of the unequal number of columns.
cache
client - file - target - many other columns
main
client - file - target - few other columns
From cache I would like all columns for which main.target LIKE '%string%', cache.client = main.client, cache.file = main.file
For these particular records, target, client and file are always the same in main and cache.
I just can't get my head around this, but then again MySQL never was my strongest point.
Thank you very much in advance!
In the end combining the two SELECT statements with a UNION made things very complicated, for the simple reason there were countless other queries, some without UNION, that in the end all had to be processed by the same end routine presenting the results. As this was only a one-time query and time wasn't really an issue, in the end I just used SELECT on the two different tables and then combined the results by checking if a certain field was present. If not, the remaining results had to be fetched from the cache table; if so, the remaining results had to be fetched from the main table.
I actually wonder whether this solution is faster, slower or just as fast.
if (!isset($row['current']))
{
$field = $row['field'];
$sqlcache = "SELECT * FROM " . $dbtable . " WHERE (client = '$sqlclient' AND file = '$sqlfile' AND field = '$field')";
$resultcache = $conn->query($sqlcache);
if (!$resultcache)
{
die($conn->error);
}
$rowcache = $resultcache->fetch_assoc();
$currenttarget = $rowcache['current'];
$context = $rowcache['context'];
$dirtysource = $rowcache['dirtysource'];
$stringid = $rowcache['stringid'];
$limit = $rowcache['maxlength'];
$locked = $rowcache['locked'];
$filei = $rowcache['filei'];
}
else
{
$currenttarget = $row['current'];
$context = $row['context'];
$dirtysource = $row['dirtysource'];
$stringid = $row['stringid'];
$limit = $row['maxlength'];
$locked = $row['locked'];
$filei = $row['filei'];
}
I'm trying to pull a full list of products from the database with the SKU, manufacturer and a custom attribute called 'GTIN'.
I'm really struggling with the custom attribute part.
This statement works to pull the manufacturer and SKU
SELECT cpe.sku, m1.manufacturer,
FROM catalog_product_entity AS cpe
INNER JOIN exportview_manufacturer AS m1 ON cpe.entity_id = m1.entity_id
My MySQL is very poor and I can't seem to get this custom attribute. I've found the following statement online which I KNOW has all the details I need to make this work but thus far I've been getting my head in a mess trying to implement it
SELECT e.entity_id AS product_id, var.value AS product_name
FROM catalog_product_entity e, eav_attribute eav, catalog_product_entity_varchar var
WHERE
e.entity_type_id = eav.entity_type_id
AND eav.attribute_code = 'gtin'
AND eav.attribute_id = var.attribute_id
AND var.entity_id = e.entity_id
I simply need the first statement to also include the 'gtin' column, but joining is where I'm falling short. Can someone please assist?
You need to create one PHP script to get all product and it's attribute. So first create all_product.php file on your Magento root and add below code.
error_reporting(E_ALL);
ini_set("display_errors", 1);
require_once '../app/Mage.php';
Mage::app();
$collection = Mage::getModel('catalog/product')->getCollection()
->addAttributeToSelect('*') // select all attributes
->setPageSize(5000) // limit number of results returned
->setCurPage(1); // set the offset (useful for pagination)
foreach ($collection as $product) {
echo $product->getName(); //get name
/*you can get any attribue you want like name above. Even you can get all custom attribule for product for that you need to use print_r($collection->getData()) above foreach*/
}
Hope it will work.
I have written a SQL query, which extracts the lowest weekly price for a property stored in my database:
var rPropertyId = Request.QueryString["PropertyID"];
var cheapestrate = "SELECT TOP 1 * FROM RateInfo WHERE PropertyID=#0 ORDER BY RateWeekly ASC";
var qcheapestrate = db.QuerySingle (cheapestrate, rPropertyId);
I'm pretty confident that this statement is correct. The problem i have, is that not ALL propertys have pricing, so i only want to show this price if they do. I have created the below if statement, but it's telling me i'm missing an ; somewhere?
#if(qcheapestrate=!null){
Rates From qcheapestrate.rateweekly per week
}
So i'm trying to check if the query returns an entry. if it does, i want to show the lowest "rateweekly" value. Hopefully this all makes sense!
Try this...
#if(qcheapestrate!=null){
<text>Rates From</text>
#qcheapestrate.rateweekly
<text>per week</text>
}
I have found many calculations here and some php examples and most are just over my head.
I found this example:
SELECT b.zip_code, b.state,
(3956 * (2 * ASIN(SQRT(
POWER(SIN(((a.lat-b.lat)*0.017453293)/2),2) +
COS(a.lat*0.017453293) *
COS(b.lat*0.017453293) *
POWER(SIN(((a.lng-b.lng)*0.017453293)/2),2))))) AS distance
FROM zips a, zips b
WHERE
a.zip_code = '90210' ## I would use the users submitted value
GROUP BY distance
having distance <= 5; ## I would use the users submitted value
But, I am having trouble understanding how to implement the query with my database.
It looks like that query has all I need.
However, I cannot even find/understand what b.zip_code actually is! (whats the b. and zips a, zips b?)
I also do not need the state in the query.
My mySQL db structure is like this:
ZIP | LAT | LONG
33416 | 26.6654 | -80.0929
I wrote this in attempt to return some kind of results (not based on above query) but, it only kicks out one zip code.
## Just for a test BUT, in reality I desire to SELECT a zip code WHERE ZIP = the users submitted zip code
## not by a submitted lat lon. I left off the $connect var, assume it's there.
my $set1 = (26.6654 - 0.20);
my $set2 = (26.6654 + 0.20);
my $set3 = (-80.0929 - 0.143);
my $set4 = (-80.0929 + 0.143);
my $test123 = $connect->prepare(qq{SELECT `ZIP` FROM `POSTAL`
WHERE `LAT` >= ? AND `LAT` <= ?
AND `LONG` >= ? AND `LONG` <= ?}) or die "$DBI::errstr";
$test123->execute("$set1","$set2","$set3","$set4") or die "$DBI::errstr";
my $cntr;
while(#zip = $test123->fetchrow_array()) {
print qq~$zip[$cntr]~;
push(#zips,$zip[$cntr]);
$cntr++;
}
As you can see, I am quite the novice so, I need some hand holding here with verbose explanation.
So, in Perl, how can I push zip codes into an array from a USER SUBMITTED ZIP CODE and user submitted DISTANCE in miles. Can be a square instead of a circle, not really that critical of a feature. Faster is better.
I'll tackle the small but crucial part of the question:
However, I cannot even find/understand what b.zip_code actually is! (whats the "b." and "zips a, zips b"?)
Basically, the query joins two tables. BUT, both tables being joined are in fact the same table - "zips" (in other words, it joins "zips" table to itself"). Of course, since the rest of the query needs to understand when you are referring to the first copy of the "zips" table and when to the second copy of the "zips" table, you are giving a table alias to each copy - to wit, "a" and "b"'.
So, "b.xxx" means "column xxx from table zips, from the SECOND instance of that table being joined".
I don't see what's wrong with your first query. You have latitude and longitude in your database (if I'm understanding, you're comparing a single entry to all others). You don't need to submit or return the state that's just part of the example. Make the first query work like this:
my $query = "SELECT b.zip_code,
(3956 * (2 * ASIN(SQRT(
POWER(SIN(((a.lat-b.lat)*0.017453293)/2),2) +
COS(a.lat*0.017453293) *
COS(b.lat*0.017453293) *
POWER(SIN(((a.lng-b.lng)*0.017453293)/2),2))))) AS distance
FROM zips a, zips b WHERE
a.zip_code = ?
GROUP BY distance having distance <= ?";
my $sth = $dbh->prepare($query);
$sth->execute( $user_submitted_zip, $user_submitted_distance );
while( my ($zip, $distance) = $sth->fetchrow() ) ) {
# do something
}
This won't be that fast, but if you have a small record set ( less than 30k rows ) it should be fine. If you really want to go faster you should look into a search engine such as Sphinx which will do this for you.
fetchrow_array returns a list of list references, essentially a two-dimensional array, where each row represents a different result from the database query and each column represents a field from the query (in your case, there is only one field, or column, per row).
Calling while ($test123->fetchrow_array()) will cause an infinite loop as your program executes the query over and over again. If the query returns results, then the while condition will be satisfied and the loop will repeat. The usual idiom would be to say something more like for my $row ($test123->fetchrow_array()) { ..., which will only execute the query once and then iterate over the results.
Each result is a list reference, and the zip code you are interested in is in the first (and only) column, so you could accumulate the results in an array like this:
my #zips = (); # for final results
for my $row ($test123->fetchrow_array()) {
push #zips, $row->[0];
}
or even more concisely with Perl's map statement:
my #zips = map { $_->[0] } $test123->fetchrow_array()
which does the same thing.
I need to amend (via CONCAT, presumably) something to every wordpress post if it belongs to a certain category (say, category ID 7), but I'm struggling to get it to work.
To test, I'm first trying to select all the relevant posts. So far, I have the following:
SELECT post_title
FROM cruise_wp_posts
LEFT JOIN cruise_wp_term_relationships
ON cruise_wp_term_relationships.object_id = cruise_wp_posts.ID
WHERE term_taxonomy_id = 87;
However, it only lists posts that are only in category 87 - I need all posts that are in category 87 (and possibly other categories too)
I'm a MySQL newbie, and this is really breaking my brain.
Any pointers would be passionately welcomed.
The best way to do it is to filter it in as needed. This way the addition is made everywhere the_content is used and not just in the templates you modify.
<?php
function my_content_concat($the_content) {
if (in_category(7)) {
$the_content .= '<br /><br />foo!';
}
return $the_content;
}
add_filter('the_content', 'my_content_concat', 9);
?>
in_category can take the id, name or slug of your target category.
I put the filter at 9 so that it runs before WordPress texturizes the content. If you don't need that run it at 11.
Why not just use get_the_category( $id ) and ammend the text when you output the post?
$cat = get_the_category( $postID );
if ($cat == 7) {
//Add text here
}
