To remove duplicate rows in Laravel, you can use the distinct() method or the groupBy() method together with the select() method. Here's how you can do it:


Method 1: Using distinct()

  1. Import the DB facade at the top of your file:
1
use IlluminateSupportFacadesDB;


  1. Write the query to select distinct rows:
1
$distinctRows = DB::table('your_table')->distinct()->get();


Method 2: Using groupBy() and select()

  1. Import the DB facade at the top of your file:
1
use IlluminateSupportFacadesDB;


  1. Write the query to select distinct rows:
1
$distinctRows = DB::table('your_table')->select('*')->groupBy('column_name')->get();


In both methods, replace 'your_table' with the name of your table and 'column_name' with the column that you want to use for removing duplicates. If you want to select all columns, use '*' as shown above.
