Use MySQL's DISTINCT keyword to remove duplicate rows

You can use MySQL's DISTINCT keyword to remove duplicate rows. Here is an example:

SELECT DISTINCT column_name
FROM table_name;

The above statement will return all unique values ​​in the specified columncolumn_name. You need to replace column_name with the column name you want to duplicate, and table_name with your table name.

If you want to remove duplicate records from an entire row, you can use MySQL's DISTINCT keyword with multiple column names. For example:

SELECT DISTINCT column_name1, column_name2, ...
FROM table_name;

The above statement will return all unique combinations in the specified multiple columns. You need to replace column_name1, column_name2, ... with the column name you want to duplicate, and table_name with your table name.
