How can I create Insert...Select statements in Laravel efficiently?

Creating Insert...Select Statements in Laravel

In the realm of database manipulation, the Insert...Select statement performs a dual function of inserting data into a table while simultaneously referencing data from another table. Laravel's robust Eloquent ORM and Query Builder offer efficient ways to construct such queries.

Query Conversion using Laravel

To convert the provided SQL query to Laravel, we cannot use a single unified query due to limitations in the current version of Laravel. However, we can achieve the desired functionality by splitting the query into two parts:

Part 1: Creating a Laravel Select Query

Begin by creating a Laravel Select query using the Eloquent ORM or Query Builder. This query should resemble the select portion of your original SQL query:

<code class="php">$select = User::where(...)
->where(...)
->whereIn(...)
->select(['email', 'moneyOwing']);</code>

Part 2: Inserting Data using Laravel Query Builder

Now, you need to use Laravel's Query Builder to construct the insert portion of your query.

<code class="php">$insertQuery = 'INSERT into user_debt_collection (email, dinero) ' . $select->toSql();
\DB::insert($insertQuery, $select->getBindings());</code>

In the above code, we manually construct the insert query using $insertQuery and then utilize DB::insert() to execute the query, providing it with both the query string and the query bindings.

Update for Laravel 5.7

Laravel 5.7.17 introduced the ->insertUsing() method, which combines the functionality of the select and insert queries into a single method.

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

This simplified method streamlines the process of creating Insert...Select statements in Laravel.
