How to Create a Database in MySQL

How to Create a Database in MySQL Data is a small unit of information. That information can be anything like text, image, name, age, class etc. β€˜Data’ word is taken from the word β€˜datum’ that means β€˜single piece of information.’ We can store data in the paper, hard disk, server and much more. Data is not in a structured form.

Example: Name, is, my, Arun.
Above Example, all information is a single piece of data. That is called Data.

Nowadays almost everything comes on the internet. It’s very difficult to handle too much data with accuration. For handling too much data with accurate, Database content came in the Market.

What is Database

The DataBase is a Collection of Raw Data. We can store data in the form of Tables, index, columns and much more. The database helps to store the data in a structured form (Tables). So it will easy to do major operations like modification, insertion, retrieving and much more.

Before Database, File System is used for storing and manipulate the data. File System has many advantages and disadvantages.

In MySql Database, we store our data in the tables. Tables will create under particular Database. In Our case, we have created Database with the name β€œtest_db”. Now we will create a new table under β€œtest_db” Database.

MySQL Create Table

MySQL Create Table Command is used to create Table inside Database. The table contains Rows and Columns. Table Creation command required the following fields.

1.) Name of the Table

CREATE TABLE Table_Name (column_name1 column_type,column_name2 column_type..);  

Now we are going to create table “MyFirst_Table” in the Database “test_db”.Follwoing commands is used of create Table in Database.

CREATE TABLE MyFirst_Table (  
   MyFirst_Table_firstname VARCHAR(200) NOT NULL,  
   MyFirst_Table_surname VARCHAR(200) NOT NULL,
   MyFirst_Table_fname VARCHAR(200) NOT NULL,  
   PRIMARY KEY ( MyFirst_Table_id )  
  • In the above command “MyFirst_Table” is the table name.
  • INT indicates Datatype of field (Column) MyFirst_Table_id.
  • NOT NULL indicates , we cannot leave this field as blank. We have to insert value in it.
  • VARCHAR (200) indicates Datatype , we can insert any type of value like Integer, string etc.
  • AUTO_INCREMENT indicates , Every time while inserting row it’s value increment by 1.

First syntax used when we want to insert in some fields.


INSERT INTO MyFirst_Table( MyFirst_Table_firstname,MyFirst_Table_surname,MyFirst_Table_fname ) VALUES ('Desy', 'kumar', 'Johny');  

Second Syntax is used , when we want to insert in all fields.

INSERT INTO MyFirst_Table VALUES ( 1,'Desy', 'kumar', 'Johny');
