DB Transactions In Laravel

Hi readers, If you are new to Laravel or just starting with web development, you might have heard about the term “transactions”. We use transactions in Laravel as an essential concept that is widely used to maintain data consistency.

What are Transactions in Laravel?

In Laravel, we use Transactions to ensure that the database remains in a consistent state by executing a set of database operations as a single unit of queries. This guarantees that all operations are either committed or rolled back in case of an error. For example, if you are running a group of queries and any one query failed then not even one query will execute.

Why are Transactions Important?

Executing multiple queries simultaneously can potentially cause inconsistencies in the database. But transactions ensure that the database remains in a consistent state. Thus, transactions play an important role in maintaining the integrity of the database. Transactions allow us to avoid the risk of data corruption. This Ensures that your application is always in a predictable state.

For example, suppose we are creating a new user in your database, and at the same time, we are also updating the user’s profile. To avoid inconsistencies, we would execute these operations together as a transaction in that case.

Using Transactions in Laravel

Using transactions in Laravel is simple, and you can use the DB facade to start a transaction, commit it or roll it back. Here is an example of how you can use transactions in Laravel:

DB::beginTransaction();

try {
    // Your database queries
    DB::table('users')->insert(['name' => 'John Doe', 'email' => 'johndoe@example.com']);
    DB::table('profiles')->where('user_id', 1)->update(['phone' => '1234567890']);

    DB::commit();
} catch (\Exception $e) {
    DB::rollback();
}
