Answer 1

In SQL-Server it would be easy using ROW_NUMBER, but alas MySQL doesn't have a function like that :-(

Best way to solve it would be as follows:

• Create a new table identical in structure to the first, but with no data.
• Use the query: INSERT INTO name_of_new_table SELECT DISTINCT * FROM name_of_old_table
• Drop the old table
• Rename the new table to whatever the old table was called.
