How to Pluck Multiple Columns In Laravel?

To pluck multiple columns in Laravel, you can use the pluck method on the database query builder object. Simply pass an array of column names to the pluck method and it will return a collection of the specified columns. For example:

1

$data = DB::table('users')->pluck(['name', 'email']);

This will retrieve only the 'name' and 'email' columns from the 'users' table and store them in the $data variable. You can then use this collection of columns as needed in your application.

How to pluck columns from a query builder instance in Laravel?

In Laravel, you can pluck specific columns from a query builder instance using the pluck method. Here's an example:

1

$users = DB::table('users')->pluck('name');

In the above example, we are selecting the name column from the users table and storing the results in the $users variable. You can also pluck multiple columns by passing an array of column names to the pluck method:

1

$users = DB::table('users')->pluck(['name', 'email']);

This will return a collection of arrays with the name and email columns of each user.

What is the role of Soft Deleted records while plucking columns in Laravel?

Soft deleted records are records that have been marked as deleted in the database but are not physically removed from the database. In Laravel, when plucking columns from a model, soft deleted records are not included by default unless explicitly specified.

When plucking columns from a model in Laravel, the soft deleted records can be included by adding the withTrashed() method to the query. This method will include the soft deleted records in the results.

Alternatively, you can exclude the soft deleted records by using the withoutTrashed() method, which will only return non-deleted records.

Overall, the role of soft deleted records while plucking columns in Laravel is to allow developers to easily work with deleted records without permanently deleting them from the database.

How to select specific columns in Laravel query?

To select specific columns in a Laravel query, you can use the select method.

Here's an example:

1
2
3

$users = DB::table('users')
            ->select('id', 'name', 'email')
            ->get();

In this example, we are selecting the columns 'id', 'name', and 'email' from the 'users' table.

You can also use the DB facade in Eloquent queries to select specific columns.

1

$users = User::select('id', 'name', 'email')->get();

This query will select the columns 'id', 'name', and 'email' from the 'users' table using Eloquent ORM.

By selecting specific columns in your query, you can optimize the performance of your application by reducing the amount of data fetched from the database.

What is the alternative method for plucking columns in Laravel?

An alternative method for plucking columns in Laravel is to use the select method along with the pluck helper function.

For example:

1

$users = User::select('id', 'name')->get()->pluck('name', 'id');

This syntax allows you to select specific columns from the database table and then use the pluck function to retrieve the values of a specific column as an associative array where the specified column is the key and another specified column is the value.
