In MySQL, you can use the DISTINCT keyword to remove duplicates, which can be applied to columns or expressions in the SELECT statement.<\/p>\n

Here is an example of using the DISTINCT keyword to remove duplicates:<\/p>\n

    \n
  1. Remove all columns from the duplicate table.<\/li>\n
  2. Select all unique rows from the table.<\/li>\n
  3. Remove specified columns_duplicates.<\/li>\n
  4. Get unique values from specified columns in the table.<\/li>\n
  5. De-duplication expression:<\/li>\n
  6. Choose unique combinations of column1 and column2 and store it as new_column in the table called table_name.<\/li>\n<\/ol>\n

    Please note that the DISTINCT keyword is used for removing duplicates from entire rows, meaning it will only return unique rows. If you want to remove duplicates from specific columns or expressions, you need to specify those columns or expressions in the SELECT statement.<\/p>\n","protected":false},"excerpt":{"rendered":"
