Delete duplicates in a SQL table

Is there SQL I can write to examine a column in a table and delete all duplicates.

For example column name "code", there are 2 entries with code = 8011, delete 1 (either).

if all duplicate records are identical (all fields having same values), then you have to delete all duplicate records and then re-insert the single record back to your table.
