I am using SphinxQL build with zend db style queries sphinx, it works great.
https://github.com/FoolCode/SphinxQL-Query-Builder
I am trying to figure out how to get total_found number from the query.
I try SphinxQL::create($this->conn)->query('SHOW META'), but it seems the return array doesn't have total_found column.
Or I have to run another query to count the result.
thanks
Ok, I just try it and works, I missed the ->execute() part, so it works well now.

I'm trying to retrieve rows from a class called Consultations using a column called userPointer. It should be straight forward but I've been struggling with this for couple of days:
Let us for example say I would like to get the first object
where userPointer = ttnRYrdu0J
Note: I will replace ttnRYrdu0J with PFUser.current() later to be dynamic if this works.
I wrote the code like this:
Unfortunately it doesn't work, however when I use any other columns such as objectId or type it works fine.
Any help please!!
Thanks
I've got the answer I used PFUser.current() instead of hard coding it which is what I want at the end because I want to show the consultations of the current user and it worked! I'm still confused why it is not working when I hard code the value but I got what I want.
Can you help me.Actually i'm using restkit in my project,i have done all my works in this project except this.In here,have to shortlist several restkit objects with key param(class object) as activity_created.pls find my code in below screenshot and give me the better solution.
this code just reverse my list.
Thanks to answer me Guys.i found solution for my question,as follows
and this is working fine..
I have a problem which I have been trying to resolve since yesterday. I am trying to pass an SQL Query via $wpdb on wordpress but I keep getting an empty array when I try to echo the result.
I have tried print_r and var_dump and both are giving me empty values. I would appreciate if someone can help as I cannot seem to get this thing sorted.
I have also tried calling the table via the db prefix with still no success.
Below is the code I have been using
<?php
global $wpdb;
$results = $wpdb->get_results("SELECT CURRENT FROM upper_winds WHERE LVL=&level AND REGION=®ion AND VALID=&valid");
echo $results;
?>
P.S I have also tried get_var with the same problems.
Thanks
I noticed you weren't accounting for the wordpress database prefix, which could be why your results aren't showing up. You can prepend the prefix to your table name by using $wpdb->prefix.
I would suggest trying the following code:
global $wpdb;
$results = $wpdb->get_results("SELECT * FROM ".$wpdb->prefix."upper_winds WHERE LVL = 'level' AND REGION = 'region' AND VALID = 'valid'");
echo $results;
I also just wanted to point out that it's important to use $wpdb->prepare to protect against SQL Injection attacks. Any time you are writing your own SQL, you need to use $wpdb->prepare. However when you use methods like $wpdb->insert or $wpdb->update that don't require you to write any SQL, then you do not need to use $wpdb->prepare because those functions take care of SQL Escaping for you. I can't provide sample code without knowing which of your values are strings and which values are integers.
See: http://codex.wordpress.org/Class_Reference/wpdb#Protect_Queries_Against_SQL_Injection_Attacks
you need to prefix your table more than likely this is wp_ etc..
<?php
global $wpdb;
$results = $wpdb->get_results("SELECT * FROM `wp_upper_winds`
WHERE `LVL`='$level'
AND `REGION`='$region'
AND `VALID`='$valid'
");
var_dump ($results);
?>
you are looking for strings in your columns but using the &?
Thanks for your great advice and input. Eventually I got it to work.
The problem was not only in the code as I had been changing my code many times to try to find the solution. Eventually the main problem was nailed down to the table. Within one of the columns I had data which was something like this 'EU-VFR'. Apparently $wpdb did not pick up values with a '-'. Luckily with your help and some debugging I realised.
Here is what I got now http://howtoflyahelicopter.com/upper-winds-and-temp/
Thanks again :)
I've tried doing this with Umbraco 6.1.6. I've pretty much implemented what Drew did here: http://our.umbraco.org/forum/developers/extending-umbraco/23200-Lucene-with-spatialnet?p=0
I'm storing lat and long data in umbraco nodes. The nodes are being indexed as encided values with tiers. But, I am not returning any results when I add the DistanceFilter to the query.
I'm just wondering if anyone else has tried this and got it working. Perhaps you can post some code.
Thanks.
Josh,
Have you inspected the index using luke just to ensure that fields are there? Also have you tried running raw queries (get the generated query written out using code) on the index using luke?

Using a default index, one can do nodeIndex.get("message", "Hello") for exact matches, or nodeIndex.query("message", "Hel*") for approximate Lucene-based queries. This works correctly for me from Java.
But how do I do approximate queries through the webadmin Data Browser interface? Exact matches work fine, such as:
node:index:nodeIndex:message:"Hello"
but I can't see how to do the wildcard queries. The syntax is shown in the pop-up help panel as:
node:index:[index]:[query]
but I don't know what to put for the [query] part, and can't find any examples of this in the manual or the wiki. Have tried the following without success:
node:index:nodeIndex:"message:Hel*"
node:index:nodeIndex:message:"Hel*"
node:index:nodeIndex:"Hel*"
node:index:nodeIndex:Hel*
This should work:
node:index:nodeIndex:message:Hel*
The queryis message:Hel* so you just append it, more complex queries are also possible.
See the lucene syntax guide.
node:index:nodeIndex:message:Hel* OR message:Wor*
