Create User

The keyword is used to create a new user in the Oracle database.

Identified By clause:

• In the above syntax Identify By Clause followed by password is used to set the login password for the user to access the database.
• Identified By Clause followed by externally states that, the access of the user is handled by any third party. However, when followed by Globally keyword states that it has global access.

Tablespace:

• Default Tablespace name1 in the above syntax is a space that is generated for storing the object that will be created by the user.
• Temporary Tablespace name2 in the above syntax is the space that is meant to store the temporary object that will be created. 
• Note: By default, the default tablespace name is set as users ie. name1=users.

Quota:

• QUOTA SIZE on name1 keyword in the above syntax is used to allocate the maximum amount of space that can be used by the user. Quota is followed by size in M(megabyte) or you can simply write unlimited.
• Make sure to always use the name1 that is the name of the default tablespace with Quota.

Password Expires:

• This statement helps the user to change the password just before login into the database.

Account LOCK|UNLOCK:

• This statement summarises the status of the Account that is created. ACCOUNT UNLOCK is used to unlock the account if it is locked.
