";" Cannot be added at the end of the logon to the database using the command line sqlplus. Otherwise, an error is reported.

For example, you need to write sqlplus username/password @ database instead of sqlplus username/password @ database;

1. Create a user

Generally, use sqlplus system/manager @ database to log on to the database first. Do not add ";". The manager here is the default. If the last modification is made during database creation

In this case, you should change it to your own password.

Then use

Create username identified by password; note that ";" is required here. ";" Is required for each command after logon.

2. Grant Permissions

The simplest method is grant DBA to username;

It can also be complicated: grant create table, create view to username; that is, grant specific permissions to users.

3. exit;

In this way, you can use the newly created user to log on: sqlplus username/password @ database. Do not add ";".

OK.
