如何在PL/SQL游标中输入参数？

CURSOR cursor_name (param1 datatype, param2 datatype) IS
SELECT column1, column2
FROM table_name
WHERE condition;

CURSOR cursor_name (param1 datatype, param2 datatype) IS
SELECT column1, column2
FROM table_name
WHERE column1 = param1 AND column2 = param2;

DECLARE
  param1_value datatype;
  param2_value datatype;
BEGIN
  param1_value := 'value1';
  param2_value := 'value2';
  
  FOR cursor_row IN cursor_name(param1_value, param2_value) LOOP
    -- 处理游标返回的数据
  END LOOP;
END;
