我想打印 sql 查询的执行统计信息。为此，我想使用自动跟踪。当我在解释上使用自动跟踪时，我没有问题，它可以正确打印所有内容。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……那有什么问题？
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：
打印组合获取的命令是什么，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
