How to create a new table in Oracle?

 To create a new table in Oracle, you can use the CREATE TABLE statement. Here's the basic syntax:

CREATE TABLE table_name (
    column1 datatype [optional_parameters] [column_constraint],
    column2 datatype [optional_parameters] [column_constraint],
    column3 datatype [optional_parameters] [column_constraint],
    ...
    [table_constraint]
);

Here's an example that creates a new table named employees:

CREATE TABLE employees (
    id NUMBER(10) PRIMARY KEY,
    first_name VARCHAR2(50),
    last_name VARCHAR2(50),
    email VARCHAR2(100),
    hire_date DATE
);

This statement creates a new table named employees with five columns: id, first_name, last_name, email, and hire_date. The id column is defined as a number data type with a maximum length of 10 digits and is set as the primary key using the PRIMARY KEY constraint. The first_name, last_name, and email columns are defined as variable-length character strings with maximum lengths of 50, 50, and 100 characters, respectively. The hire_date column is defined as a date data type.

Once the table is created, you can insert data into it using the INSERT INTO statement and query the data using the SELECT statement.
