如何将模式名和表名作为输入，然后在plsql中获得内存大小和row_count作为输出

CREATE OR REPLACE PROCEDURE get_memory_size_and_row_count(p_schema_name VARCHAR2, p_table_name VARCHAR2, p_memory_size OUT NUMBER, p_row_count OUT NUMBER) AS
  v_sql VARCHAR2(1000);
BEGIN
  -- 构建动态SQL语句
  v_sql := 'SELECT BYTES, NUM_ROWS FROM ALL_TABLES WHERE OWNER = ''' || p_schema_name || ''' AND TABLE_NAME = ''' || p_table_name || '''';

  -- 执行动态SQL语句并获取结果
  EXECUTE IMMEDIATE v_sql INTO p_memory_size, p_row_count;
END;
/

DECLARE
  v_memory_size NUMBER;
  v_row_count NUMBER;
BEGIN
  -- 调用存储过程并传入模式名和表名
  get_memory_size_and_row_count('SCHEMA_NAME', 'TABLE_NAME', v_memory_size, v_row_count);

  -- 输出结果
  DBMS_OUTPUT.PUT_LINE('Memory Size: ' || v_memory_size || ' bytes');
  DBMS_OUTPUT.PUT_LINE('Row Count: ' || v_row_count);
END;
