# Adds a new index to the table. +column_name+ can be a single Symbol, or

- # When creating an index on multiple columns, the first column is used as a name
- # for the index. For example, when you specify an index on two columns
- # [<tt>:first</tt>, <tt>:last</tt>], the DBMS creates an index for both columns as well as an
- # index for the first column <tt>:first</tt>. Using just the first name for this index
- # makes sense, because you will never have to create a singular index with this
- # name.
