Yes. Oracle calls them collections and there's a variety of collections you can use.
是的。Oracle 将它们称为集合，您可以使用多种集合。
A simple array example using a VARRAY.
使用 VARRAY 的简单数组示例。
DECLARE
TYPE Str_Array IS VARRAY(4) OF VARCHAR2(50);
v_array Str_Array;
PROCEDURE PROCESS_ARRAY(v_str_array Str_Array)
AS
BEGIN
FOR i IN v_str_array.first .. v_str_array.last LOOP
DBMS_OUTPUT.PUT_LINE('Hello '||v_str_array(i));
END LOOP;
END;
BEGIN
v_array := Str_Array('John','Paul','Ringo','George');
PROCESS_ARRAY(v_array);
-- can also pass unbound Str_Array
PROCESS_ARRAY(Str_Array('John','Paul','Ringo','George'));
END;

If I'm not wrong, there's a native type called TABLE that basically is an array. But last time I used it was 2001 so maybe there are most powerful types nowadays.
如果我没记错的话，有一个叫做 TABLE 的原生类型，它基本上是一个数组。但是我上次使用它是在 2001 年，所以也许现在有最强大的类型。
