Rebuild SCOTT users and SCOTT stories

Rebuild SCOTT users and SCOTT stories

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

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.

This is about to be traced back to Oracle's entrepreneurial stage. In June 1977, Accenture, Bob Miner, and Ed Oates jointly established a computer company named Software Development Lab (SDL) in Silicon Valley, the three-person Company was the predecessor of ORACLE, which later became the dominant database provider. At that time, herison was 32 years old. He was just as old as me. Because of his contract relationship, he was not able to come out in his original company. He was just a programmer. He can't survive. He always needs someone who writes code. The first programmer in the company appeared. His name is scott, and his cat name is trigger, it may be for the sake of the first programmer, so we have the user scott and have never forgotten it.

In March 1983, RSI released the third edition of ORACLE. Miner and Scott used the C language to develop the third edition under the high pressure of herison, using it to write ORACLE software is also risky, but there is no other way. It soon proved how correct it was: C compiler is cheap and effective, and has good portability.

However, this third edition is not over yet. Scott left Oracle, and perhaps the endless changes in c development and initial stages left scott unable to bear. The Bull chose to leave the company and sell his 4% million shares, but after scott leaves Oracle, he is still confused in the database development market. He founded PointBase, which is a good embedded database, but it seems to be written in java, I have also used development projects. The Daniel did not think that Oracle, which was written by him in the future, is the database giant in the future, and the 4% is equivalent to several hundred million US dollars.
