Create a Insert… Select statement in Laravel

Question

I\'m needing to convert this query for Laravel and I\'m having issues trying to create an Insert... Select statement using Laravel\'s Eloquont ORM, or Queries. I\'m not sure

Answer 1

Try this

DB::table(table2)
    ->insert(
        (array) DB::table(table1)
            ->where('column', '=', $variable)
            ->select('column1','column2')
            ->first()
    );

Answer 2

I used DB::statement(...);

BD::statement(INSERT INTO table (SELECT));

Answer 3

First, you'll need to create a model for Demand, so then you can use:

$demand = new Demand;
$demand->Login = $login;
$demand->Name = $name;
[...]
$demand->save(); // <~ this is your "insert" statement
$id = $demand->id;

Then for your select statement you can do something similar to these options:

$demand = Demand::find($id); // will be similar to: SELECT * FROM Demand WHERE `id` = '$id';
$demand = Demand::where('id', $id)->get(); //same as above
$demand = Demand::where('id', $id)->get(array('Login', 'Name')); // will be similar to: SELECT `Login`, `Name` FROM Demand WHERE `id` = '$id';

There is a lot more information in the manual here and here

There is no way of doing this in one query (unless you are on Laravel 5.7), however I came across the same issue and wanted to make sure I can keep using a certain select I build with the QueryBuilder.

So what you could do, to keep things half what clean and to reuse functionality which has built a select statement before, is this:

/**
 * Wherever your Select may come from
 **/
$select = User::where(...)
                  ->where(...)
                  ->whereIn(...)
                  ->select(array('email','moneyOwing'));
/**
 * get the binding parameters
 **/ 
$bindings = $select->getBindings();
/**
 * now go down to the "Network Layer"
 * and do a hard coded select, Laravel is a little
 * stupid here
 */
 $insertQuery = 'INSERT into user_debt_collection (email,dinero) '
                . $select->toSql();

 \DB::insert($insertQuery, $bindings);

UPDATE Laravel 5.7

As of Laravel 5.7.17 you can use ->insertUsing(). See here for details. Thank you @Soulriser for pointing this out.

So above query would look like this:

DB::table('user_debt_collection')->insertUsing(['email','dinero'], $select);

In Laravel 5.5, I created a helper function for executing easier:

class QueryHelper
{

    /**
     * @param string $model
     * @param array $columns
     * @param Builder $select
     * @return bool
     */
    public static function insertFromSelectStatement($model, $columns, $select)
    {
        /** @var \Illuminate\Database\Query\Builder $query */
        $query = (new $model)->getQuery();
        $sql = "insert into {$query->from} (". implode(', ', $columns) .") {$select->toSql()}";
        return $query->getConnection()->insert($sql, $select->getBindings());
    }
}

For example:

$notification = Notification::create([
    'title' => 'this is title',
    'message' => 'this is message',
]);
$now = DB::raw("'". Carbon::now()->toDateTimeString() ."'");
$selectActivatedUsers = User::select('id', $notification->id, $now, $now)->where('status', '=', 'activated');
// insert notifications to activated users
QueryHelper::insertFromSelectStatement(UserNotification::class, ['user_id', 'notification_id', 'created_at', 'updated_at'], $selectActivatedUser);

Answer 6

You can use:

DB::insert("insert into contacts(contact_id,contact_type,account_id,created_at,updated_at) select f.id,'App\\Friend',f.account_id,f.created_at,f.updated_at from friends as f where f.id=?",[16]);
