⟩ How To Create an Array in PL/SQL?
If you want create an array data structure, you can use the collection type VARRAY. VARRAY stands for Variable Array. Here is a sample script on how to use VARRAY:
SQL> set serveroutput on;
SQL> DECLARE
2 TYPE list IS VARRAY(3) OF VARCHAR(16);
3 domain_list list;
4 BEGIN
5 domain_list := list('google','globalguideline','myspace');
6 DBMS_OUTPUT.PUT_LINE('Second domain: '
7 || domain_list(2));
8 END;
9 /
Second domain: globalguideline
As you can see, to define an array variable, you need to create your own array type, and use that type to define array variables.
