Laravel - how to get the query with bind parameters?

Question

I can get the not-bind query on with this way :

\DB::enableQueryLog();
$items = OrderItem::where('name', '=', 'test')->get();
$log = \DB::getQueryLog();
print_r($log);

Output is :

(
    [0] => Array
        (
            [query] => select * from "order_items" where "order_items"."name" = ? and "order_items"."deleted_at" is null
            [bindings] => Array
                (
                    [0] => test
                )
            [time] => 0.07
        )
)

But what I really need is bind query like this :

select * from "order_items" where "order_items"."name" = 'test' and "order_items"."deleted_at" is null

I know I can do this with raw PHP but is there any solution in laravel core?

Actually I've created one function within helpers.php for same. You can also use same function within your helpers.php file

if (! function_exists('ql'))
{
    /**
     * Get Query Log
     *
     * @return array of queries
     */
    function ql()
    {
        $log = \DB::getQueryLog();

        $pdo = \DB::connection()->getPdo();

        foreach ($log as &$l)
        {
            $bindings = $l['bindings'];

            if (!empty($bindings))
            {
                foreach ($bindings as $key => $binding)
                {
                    // This regex matches placeholders only, not the question marks,
                    // nested in quotes, while we iterate through the bindings
                    // and substitute placeholders by suitable values.
                    $regex = is_numeric($key)
                        ? "/\?(?=(?:[^'\\\']*'[^'\\\']*')*[^'\\\']*$)/"
                        : "/:{$key}(?=(?:[^'\\\']*'[^'\\\']*')*[^'\\\']*$)/";

                    $l['query'] = preg_replace($regex, $pdo->quote($binding), $l['query'], 1);
                }
            }
        }

        return $log;
    }
}

if (! function_exists('qldd'))
{
    /**
     * Get Query Log then Dump and Die
     *
     * @return array of queries
     */
    function qldd()
    {
        dd(ql());
    }
}

if (! function_exists('qld'))
{
    /**
     * Get Query Log then Dump
     *
     * @return array of queries
     */
    function qld()
    {
        dump(ql());
    }
}

Simply place these three functions within your helpers.php file and you can use same as follows:

$items = OrderItem::where('name', '=', 'test')->get();
qldd(); //for dump and die

or you can use

qld(); // for dump only

I've replaced the return of ql() for return $log[0]['query']; and this does not works if you don't set \DB::enableQueryLog(); before the query.

Here I extended the answer of @blaz

In app\Providers\AppServiceProvider.php

Add this on boot() method

    if (env('APP_DEBUG')) {
        DB::listen(function($query) {
            File::append(
                storage_path('/logs/query.log'),
                self::queryLog($query->sql, $query->bindings) . "\n\n"
            );
        });
    }

and also added a private method

private function queryLog($sql, $binds)
{
    $result = "";
    $sql_chunks = explode('?', $sql);

    foreach ($sql_chunks as $key => $sql_chunk) {
        if (isset($binds[$key])) {
            $result .= $sql_chunk . '"' . $binds[$key] . '"';
        }
    }

    $result .= $sql_chunks[count($sql_chunks) -1];

    return $result;
}

Yeah, you're right :/ This is a highly requested feature, and i have no idea why its not a part of the framework yet...

This is not the most elegant solution, but you can do something like this:



    function getPureSql($sql, $binds) {
        $result = "";

        $sql_chunks = explode('?', $sql);
        foreach ($sql_chunks as $key => $sql_chunk) {
            if (isset($binds[$key])) {
                $result .= $sql_chunk . '"' . $binds[$key] . '"';
            }
        }

        return $result;
    }

    $query = OrderItem::where('name', '=', 'test');
    $pure_sql_query = getPureSql($query->toSql(), $query->getBindings()); 

    // Or like this:
    $data = OrderItem::where('name', '=', 'test')->get();

    $log = DB::getQueryLog();
    $log = end($log);
    $pure_sql_query = getPureSql($log['query'], $log['bindings']);

-2

You can do that with:

    OrderItem::where('name', '=', 'test')->toSql();

no no with your code output is not bind query -> select * from "order_items" where "order_items"."name" = ? and "order_items"."deleted_at" is null
