Where is the DISTINCT qualifier placed in a SELECT statement?

Explanation:
Distinct is a modifier of the SELECT clause that tells the database to remove duplicate rows from the result. The correct placement is right after SELECT, before listing the columns you want to return, as in SELECT DISTINCT column1, column2 FROM your_table. This positioning applies the deduplication to the entire select list. It isn’t placed after FROM or after WHERE, because those clauses specify the data source and filtering, while DISTINCT applies to what you’re selecting. If you want all unique rows, you can use SELECT DISTINCT * FROM your_table; for unique values in specific columns, list those columns after DISTINCT.
