Oracle was first learned from the dept and emp tables under scott, and is still used to testing under scott. Sometimes to facilitate testing, scott users need to be rebuilt to provide a completely new test environment, where the record of the process of rebuilding scott users is recorded.

1. scott user profile
SCOTT is the name of an example user in the Oracle database. Its function is to provide some simple application examples for beginners, but it is locked by default. SCOTT's default password is tiger. The following table is emp and dept. The relationship between these tables demonstrates some basic principles of relational databases. Oracle generally uses this user as an example, this user is generally used in Oracle books and textbooks. It is not necessary for Oracle itself. If you do not want to use it, you can delete it (if you do not create other objects under it ).

2. Prepare the environment
We tested Oracle 10 Gb to delete scott users.

3. Rebuilding scott users
Oracle provides the scott user's reconstruction script, which is located in the ORACLE_HOME \ RDBMS \ ADMIN directory and named utlsampl. SQL. Run the script in sys as follows:

SQL>

SQL> show user

The USER is \ "SYS \"

SQL>

SQL> @ C: \ oracle \ product \ 10.2.0 \ db_1 \ RDBMS \ ADMIN \ utlsampl. SQL

After the script is executed, the system automatically releases SQL * plus. Next, we connect to the scott user and check whether the script is successfully executed.

The script is mainly divided into several parts,
The first part is the remarks Section, with the Rem keyword at the beginning of the line, describing the evolution process of utlsampl. SQL script;
The second part is the drop object. Let's take a look at the yellow-marked statement. That is to say, the drop user statement prepared in the environment is purely superfluous, and Oracle has already thought of it for us;
The third part is to create a table and insert data.

5. Who is scott?

From the first commercial version of Oracle to the present, oracle's default database has all the users whose names are scott and whose passwords are tiger. What exactly does scott come from? How can we keep it rare in our oracle version.
