Create Table in MySQL 5.5
We will first create a database name office which will house all of our tables.
Create Office Database
[root@localhost ~]# mysql -u root Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 4 Server version: 5.5.64-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> create database office; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | office | | performance_schema | | test | +--------------------+ 5 rows in set (0.01 sec) MariaDB [(none)]>
We need to use office database to create our tables.

We will create an Employee table with column Name ID, Phone and Address.
MariaDB [office]> create table Employee -> (Name varchar(20), -> ID int not null, -> Phone int, -> Address varchar(120) -> ); Query OK, 0 rows affected (0.01 sec)
Here we will create an Account table with column name ID, Name, Salary and Salary_date.
MariaDB [office]> create table Account -> (ID int not null, -> Name varchar(20), -> Salary int, -> Salary_date date -> ); Query OK, 0 rows affected (0.00 sec)
We will create a Department Table with Column ID, Dept_Name, Dept_Manager and Dept_Strength.
MariaDB [office]> create table Department -> (ID int not null, -> Dept_Name varchar(20), -> Dept_Manager varchar(20), -> Dept_Strength int -> ); Query OK, 0 rows affected (0.01 sec)
Show all the tables in Office Database
