How to Join Only Last Record Of the Table In Laravel?

2 minutes read

To join only the last record of a table in Laravel, you can use the latest() method to get the most recent record and then use the join() method to perform the join operation.


Here is an example code snippet to achieve this:

1
2

$lastRecord = YourModel::latest()->first();
$joinedRecord = $lastRecord->join('other_table', 'other_table.id', '=', 'your_table.foreign_key')->get();


In this code snippet, YourModel represents the model associated with the table you want to query. Replace 'other_table', 'your_table', and 'foreign_key' with the appropriate table names and foreign key you need to join with.


By using latest()->first(), you are retrieving the most recent record from the table, and then you can perform the join operation using the retrieved record.


What is the significance of eager loading when fetching the last record in Laravel relationships?

Eager loading is significant when fetching the last record in Laravel relationships because it allows you to retrieve related records within the same query. This can improve performance by reducing the number of queries executed and optimizing the database calls. By eager loading related records, you can ensure that all necessary data is retrieved in one go, rather than making additional queries for each related record. This can be particularly useful when fetching the last record in a relationship, as it ensures that all related records are loaded efficiently and effectively.


How to include soft deleted records in the query while fetching the last record in Laravel?

You can include soft deleted records in your query by using the withTrashed() method. To fetch the last record in Laravel along with soft deleted records, you can do the following:

1
2

// Fetch the last record along with soft deleted records
$record = YourModel::withTrashed()->orderBy('created_at', 'desc')->first();


This query will fetch the last record of YourModel including any soft deleted records. The withTrashed() method includes soft deleted records in the query, and the orderBy('created_at', 'desc') sorts the records in descending order based on the created_at column before fetching the first record.


How to prevent fetching multiple records when trying to get only the last one in Laravel?

To prevent fetching multiple records when trying to get only the last one in Laravel, you can use the latest() method on the query builder to order the records by a timestamp column in descending order and then use the first() method to retrieve only the last record.


Here's an example:

1

$latestRecord = YourModel::latest()->first();


This query will order the records by the timestamp column in descending order and then retrieve only the first (i.e., the last) record from the result set.


Using the latest()->first() method chain ensures that only one record is fetched, even if there are multiple records in the database that meet the criteria. This can help optimize performance and reduce unnecessary database queries.
