See the section 'Querying Data Into Collections of Records' in the PL/SQL doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/collections.htm#i36282
Querying Data Into Collections of Records
You can use the BULK COLLECT clause with a SELECT INTO or FETCH statement to retrieve a set of rows into a collection of records.
That doc section shows you how to use BULK COLLECT when querying MULTIPLE values.
You use INTO for single values. You use BULK COLLECT INTO for multiple values.
