How can you remove duplicate rows from a result set in SQL?

To remove duplicate rows from a result set in SQL, you can use the DISTINCT keyword. Here are the steps:

1. Identify the table and columns from which you want to select data. For example, let's say we have a table named Employees and we want to select data from the Name column.

2. Write a basic SQL SELECT statement. Without removing duplicates, it would look like this:

   SELECT Name
   FROM Employees;
   

   This statement selects all entries in the Name column from the Employees table, including duplicates.

3. To remove duplicates, add the DISTINCT keyword to your SELECT statement:

   SELECT DISTINCT Name
   FROM Employees;
   

   This statement selects only the unique entries in the Name column from the Employees table.

Remember, DISTINCT removes duplicates based on all selected columns. If you select multiple columns and use DISTINCT, a row will only be considered a duplicate if all selected columns are identical to another row.
