我无法使用Autotrace Traceonly Oracle打印统计信息

Question

我想打印sql查询的执行统计信息。为此，我想使用autotrace。当我在解释时使用autotrace时，我没有问题，它正确打印所有内容。但是，当我想使用autotrace traceonly时，程序会说“不支持”。我的用户拥有所有权限......那么问题是什么？

set autotrace traceonly;
set timing on;

-- Here i have my 4 Querys

set timing off;

结果：

  

目前不支持Traceonly选项。

我也想打印这样的东西：

打印组合的命令是什么，就像在我的图像中一样？

有什么想法吗？

我正在使用SQL Developer和Oracle 11-G
