删除scott模式中的test1表；

要删除SCOTT模式中的test1表，您可以使用以下SQL语句：

DROP TABLE scott.test1;

这将从数据库中永久删除test1表及其相关的数据和对象。

请确保您已连接到SCOTT模式的Oracle数据库，并具有足够的权限来执行此DROP TABLE语句。如果您没有足够的权限，可能需要与数据库管理员联系以获取相应的权限。请谨慎操作，因为删除表将不可逆转并且会导致数据丢失。在执行此操作之前，请确保已经备份了重要的数据。

Scott-Knott test

The Scott-Knott test is a statistical test used to compare the performance of different treatments or interventions in an experimental study. It is a post-hoc test that allows for the identification of homogeneous groups of treatments based on their performance, and it is especially useful when dealing with a large number of treatments.

The Scott-Knott test involves sorting the treatments based on their performance and then using a hierarchical clustering algorithm to group the treatments into subsets that are statistically different from each other. The algorithm takes into account both the magnitude of the differences between treatments and their statistical significance.

The Scott-Knott test has been widely used in various fields, including agriculture, engineering, and medicine, to compare the effectiveness of different treatments and to identify the best-performing treatments for further study or implementation. It is considered a robust and reliable method for analyzing complex experimental data and has been shown to outperform other commonly used post-hoc tests, such as Tukey's HSD and Scheffe's test, in terms of power and accuracy.

利用SQL*Plus，将“stu +学号”用户授予scott模式中对dept表的查看、修改、删除对象权限；对scott模式下emp表的全部权限。

您可以按照以下步骤在SQL*Plus中完成该操作：

1. 使用sysdba用户登录数据库：

sqlplus / as sysdba

2. 创建一个用户“stu + 学号”，并设置密码：

create user stu001 identified by password;

3. 授予“stu + 学号”用户对dept表的查看、修改、删除权限：

grant select, insert, update, delete on scott.dept to stu001;

4. 授予“stu + 学号”用户对emp表的所有权限：

grant all on scott.emp to stu001;

完成以上步骤后，您就成功将“stu + 学号”用户授予了scott模式中对dept表的查看、修改、删除权限，以及对scott模式下emp表的所有权限。
