How to Efficiently Insert Data Using `Insert... Select` in Laravel?

Efficient Insertion of Data Using Insert... Select in Laravel

Query Conversion for Laravel

To convert the provided SQL query into a Laravel expression, it's crucial to understand that Laravel 5.6 and earlier versions lack direct support for Insert... Select operations. This means a direct conversion is not possible.

Alternative Approach in Laravel

However, there is a workaround that allows you to achieve the desired result. Instead of attempting a single query, you can split it into two steps:

1. Utilize Laravel's QueryBuilder to construct a Select query that retrieves the necessary data. Use the getBindings() method to extract the binding parameters.
2. Employ a raw SQL query to perform the insert using the data retrieved in Step 1. Bind the binding parameters obtained from getBindings().

Example Code:

<code class="php">// Step 1: Generate the Select query
$select = User::where(...)
                  ->where(...)
                  ->whereIn(...)
                  ->select(array('email','moneyOwing'));

// Step 2: Get binding parameters
$bindings = $select->getBindings();

// Step 3: Construct raw SQL insert query
$insertQuery = 'INSERT into user_debt_collection (email,dinero) '
                . $select->toSql();

// Step 4: Execute the insert
\DB::insert($insertQuery, $bindings);</code>

Laravel 5.7 Update

Laravel 5.7 introduced the ->insertUsing() method, providing direct support for Insert... Select. The previous example would be simplified to:

<code class="php">DB::table('user_debt_collection')->insertUsing(['email','dinero'], $select);</code>
