I want to execute a SQL query inside PL/SQL and populate the results into an associative array, where one of the columns in the SQL becomes the key in the associative array. For example, say I have a table Person with columns

PERSON_ID   INTEGER      PRIMARY KEY
PERSON_NAME VARCHAR2(50)

...and values like:

 PERSON_ID  |  PERSON_NAME
 ------------------------
 6          |  Alice
 15         |  Bob
 1234       |  Carol

I want to bulk collect this table into a TABLE OF VARCHAR2(50) INDEX BY INTEGER such that the key 6 in this associative array has the value Alice and so on. Can this be done in PL/SQL? If so, how?
