A common method involves using the UNIQUE keyword in conjunction with grouping functions. This approach can be employed to generate a non-duplicated dataset by selecting distinct values from specific columns. Another strategy utilizes the DENSE_RANK() function, which assigns a unique identifier to each row within a result set based on specified criteria. By filtering rows with duplicate identifiers, you can effectively eliminate duplicates. In some cases, utilizing UNION operations in combination with WHERE clauses can also prove effective in identifying and removing duplicate data. Remember to always back up your database before implementing any data manipulation queries to prevent unintended consequences.
