✒️ Database and Table info

  • Database Name: my_test_db
  • Table Name: users
  • users table columns: users table has three columns name, age, and email.

Note: one database can have multiple tables, which means you can create multiple tables in a single database.

So first, open your MySQL and create a Database called my_test_db.

After creating the my_test_db database, we will create a table called users inside this database.

Syntax of creating a table in a MySQL database.

CREATE TABLE table_name(

    column_name1 DATA_TYPE(SIZE)
  • DATA_TYPE – Which type of data you want to store in a Column such as – Number, String, Date.
