I am using Oracle SQL Developer

Answer 1

Use a collection:

CREATE TYPE Varchar2TableType AS TABLE OF VARCHAR2(200);

Or use a built-in type like SYS.ODCIVARCHAR2LIST or SYS.ODCINUMBERLIST:

VARIABLE cursor REFCURSOR;

DECLARE
  your_collection SYS.ODCIVARCHAR2LIST := SYS.ODCIVARCHAR2LIST();
BEGIN
  your_collection.EXTEND( 100 );

  your_collection(  1) := 'Some value';
  your_collection(  2) := 'Some other value';
  -- ...
  your_collection(100) := DBMS_RANDOM.STRING( 'x', 20 );

  OPEN :cursor FOR
  SELECT t.*
  FROM   your_table t
         INNER JOIN
         TABLE( your_collection ) c
         ON t.id = c.COLUMN_VALUE;
END;
/

PRINT cursor;
