When working on Laravel, we do query like this:
$user = DB::table('users')->where('name', 'John')->first();
How can I view the generated sql query? This is something very important for debugging during the development.
Thank you.
According to this answer, you should be able to use this to get the last executed query :
$queries = DB::getQueryLog(); // gets a log of all executed queries
$last_query = end($queries); // gets the last one
You can also add this snippet:
Event::listen('illuminate.query', function($sql)
{
var_dump($sql);
});
It will output all queries being executed in your request.
Not a direct answer as other people have answered this but take a look at this composer package, it is very helpful and displays all of your queries and more.

I know that we can get sql query from magento model collection using this,
getSelect();
But I can get query from only the model collections, not worked in others or May be I dont know how to use it.
Here I want to know what query is running behind this,
$productModel = Mage::getModel('catalog/product')->getCollection();
$attr = $productModel->getResource()->getAttribute("color");
if ($attr->usesSource()) {
echo $color_label = $attr->getSource()->getOptionText("28");
}
If I use this,
echo $productModel->getSelect(); exit;
I'm just get the one part the query only, like,
SELECT `e`.* FROM `catalog_product_entity` AS `e`
Update:
This is my full code,
<?php
require_once('app/Mage.php'); //Path to Magento
umask(0);
Mage::app();
$productModel = Mage::getModel('catalog/product')->getCollection();
$attr = $productModel->getResource()->getAttribute("color");
if ($attr->usesSource()) {
$color_label = $attr->getSource()->getOptionText("28");
}
$productModel->printlogquery(true);exit;
Please help me guys,
Your order condition is not visible in the query. The reason your order isn't showing is because the orders are added to the query during the load() method.
See Varien_Data_Collection_Db::load()
Try calling load(true) to see the complete SQL containing the order by clause.
$productModel->load(true);
$productModel->printLogQuery(true);
Hope it helps.
If you want to see what is the exact query, then you can get this by using:
$productModel->printlogquery(true);exit;
Use this code after you have loaded your model's object and applied all conditions.
I hope this will help you.
Magento collecting data with lot of internal queries - models and lot of checks, and may be more than 1 table. So it is not possible to get the query like what I'm looking for.
You might read this question every day so i tried another Stackoverflow's answer before asking:
CakePHP table is missing even when it exists
Anyways. The table i try to select data from does exist (quadra-checked uppercase/lowercase!) and it gets also listed via $db->->listSources().
Here's a screenshot of the query, the message and the last result from listing all Datasource's tables:
http://i.stack.imgur.com/CdhcV.png
Note: If i run this query in PHPMyAdmin manually it works fine. I would say its impossible to get the pictures output at one time in a view - now its up to you to tell me the opposite. By the way: I am pretty sure to use the correct Datasource.
I should tell additionally that the mysql-server is hosted on another platform. Since i can use it for my localhost-phpmyadmin if i modify the config.inc.php i can promise it is no Firewall-Problem.
Written in behalf of xcy7e:
The mistake was to execute the Query from the local Model. Here's the code:
$conn = ConnectionManager::getDataSource('myDB');
$conn->query($query);
// instead of $this->query($query);
Thinking about moving to use Laravel with Eloquent, but I know given our site eventually we'll need to ask, "So what raw SQL query is Eloquent actually generating?" so we can troubleshoot that query to see what went wrong... and I don't see that info in the docs.
So how would we pull up the query that Eloquent generated?
Fastest way is to add this to your route, controller action or even app/start/global.php:
DB::listen(function($sql, $bindings, $time) {
Log::info($sql);
});
It log it, so you can then
php artisan tail
To see your queries.
If you need to log just one query direct to the page it's almost the same, you just put it in the place the query is executed:
DB::listen(function($sql, $bindings, $time) {
var_dump($sql);
var_dump($bindings);
});
Posts::where('title', 'My First Post')->get();
die;
And it will echo it in the page.
You can also use the Clockwork Chrome extension (https://chrome.google.com/webstore/detail/clockwork/dmggabnehkmmfmdffgajcflpdjlnoemp?hl=en), this is the PHP package to be installed on Laravel: https://github.com/itsgoingd/clockwork.
Clockwork gives you a really nice profiling view of your application.
Using CI for the first time and i'm smashing my head with this seemingly simple issue. My query wont insert the record.
In an attempt to debug a possible problem, the insert code has been simplified but i'm still getting no joy.
Essentially, i'm using;
$data = array('post_post' => $this->input->post('ask_question'));
$this->db->insert('posts', $data);
I'm getting no errors (although that possibly due to disabling them in config/database.php due to another CI related trauma :-$ )
Ive used
echo print $this->db->last_query();
to get the generated query, shown as below:
INSERT INTO `posts` (`post_post`) VALUES ('some text')
I have pasted this query into phpMyAdmin, it inserts no problem. Ive even tried using $this->db->query() to run the outputted query above 'manually' but again, the record will not insert.
The scheme of the DB table 'posts' is simply two columns, post_id & post_post.
Please, any pointers on whats going on here would be greatly appreciated...thanks
OK..Solved, after much a messing with CI.
Got it to work by setting persistant connection to false.
$db['default']['pconnect'] = FALSE;
sigh
Things generally look ok, everything you have said suggests that it should work. My first instinct would be to check that what you're inserting is compatible with your SQL field.
Just a cool CI feature; I'd suggest you take a look at the CI Database Transaction class. Transactions allow you to wrap your query/queries inside a transaction, which can be rolled back on failure, and can also make error handling easier:
$this->db->trans_start();
$this->db->query('INSERT INTO posts ...etc ');
$this->db->trans_complete();
if ($this->db->trans_status() === FALSE)
{
// generate an error... or use the log_message() function to log your error
}
Alternatively, one thing you can do is put your Insert SQL statement into $this->db->query(your_query_here), instead of calling insert. There is a CI Query feature called Query Binding which will also auto-escape your passed data array.
Let me know how it goes, and hope this helps!
We use a similar query in our different code base modules and at times it gets difficult to check in General/Slow Query Log to find out the page where it got executed.
Is there anyway to pass some info to server while executing query?
You can put a comment in your queries:
$sql = "-- Called from myfile.php:
SELECT * from table;";
$res = mysql_query($sql);
The comment will be considered part of the statement and logged along with the query itself.
