SQL CREATE Database
The SQL CREATE DATABASE statement is used by a developer to create a database.
CREATE DATABASE DatabaseName;
If you want to add tables in that database, you can use CREATE TABLE statement. In MySQL, you need to create database first then table. But, you don't need to create database in Oracle. In Oracle database, you can create table directly.
SQL DROP Database
SQL DROP statement is used to delete or remove indexes from a table in the database. If you want to delete or drop an existing database in a SQL schema, you can use SQL DROP DATABASE
DROP DATABASE DatabaseName;
If you delete or drop the database, all the tables and views will also be deleted. So be careful while using this command
SQL RENAME Database
Sometimes you need to change the name of your database because of the original name was not more relevant to the data. Or, you just want to give a temporary name to that data. SQL RENAME DATABASE statement is used to change the name of a database.
RENAME DATABASE old_db_name TO new_db_name;
SQL SELECT Database

SELECT column_list FROM table_name
[GROUP BY Clause]
[ORDER BY Clause];
