How to get non-duplicate rows in Laravel?

In Laravel, you can get non-duplicate rows by using the distinct() method on your query builder.


Here's an example:

1
2
3
4
$nonDuplicateRows = DB::table('your_table_name')
            ->select('column1', 'column2', 'column3')
            ->distinct()
            ->get();


In this code snippet, replace 'your_table_name' with the name of your table and 'column1', 'column2', 'column3' with the columns you want to select from the table.


The distinct() method ensures that only unique rows are returned in the query result set. This will remove any duplicate entries based on the selected columns.


What is the code to display only unique rows in Laravel?

You can display only unique rows in Laravel using the distinct() method. Here is an example code to achieve this:

1
2
3
4
$uniqueRows = DB::table('your_table')
                   ->select('column1', 'column2')
                   ->distinct()
                   ->get();


Replace 'your_table' with the name of your table and 'column1', 'column2' with the columns you want to select. The distinct() method ensures that only unique rows are returned in the query result.


How to fetch distinct data in Laravel?

To fetch distinct data in Laravel, you can use the distinct() method along with your query builder. Here's an example of how you can fetch distinct data from a table:

1
2
3
4
$data = DB::table('table_name')
            ->select('column_name')
            ->distinct()
            ->get();


In this example, table_name is the name of the table from which you want to fetch distinct data, and column_name is the name of the column for which you want to fetch distinct values.


You can also use the groupBy() method along with select() and distinct() to fetch distinct data based on multiple columns:

1
2
3
4
$data = DB::table('table_name')
            ->select('column1', 'column2')
            ->groupBy('column1', 'column2')
            ->get();


This query will fetch distinct data based on the values of column1 and column2.


Alternatively, you can use the Eloquent ORM for fetching distinct data from a model. Here's an example using Eloquent:

1
2
3
$data = ModelName::select('column_name')
                 ->distinct()
                 ->get();


Replace ModelName with the name of your Eloquent model and column_name with the name of the column for which you want to fetch distinct values.


These are a few examples of how you can fetch distinct data in Laravel using either the query builder or Eloquent ORM.
