If we would have a single table to store everything, we would quickly have a big chaotic mess. This keeps our data structured, fast and organized. We can structure our data across multiple tables. This will output all data in the Users table from the database: $ python get.py We can use those queries in a Python program: #!/usr/bin/python You can try the commands below from the command line or from the GUI: sqlite3 user.db SQL has many commands to interact with the database. Related course: Master SQL Databases with Python This GUI can be used to modify the records (data) in the table and to add new tables. The full table including all records will be showing now. On the left is a small tree view, press Tables > users. It appears like not much has changed, do not worry, this is just the user interface. We install using: sudo apt-get install sqliteman Personally I picked sqllite-man but there are many others. sqlite> SELECT * FROM Users įrom GUI: If you want to use a GUI instead, there is a lot of choice. This will output the data in the table Users. We can explore the database using two methods: the command line and a graphical interface.įrom console: To explore using the command line type these commands: sqlite3 user.db Once we run the script the data gets inserted into the database table Users: We add records into the table with these commands: The table gets created using the command: A database can hold many different tables. The table defines the structure of the data and can hold the data. These tables can have relations with other tables: it’s called relational database management system or RDBMS. SQLite is a database management system that uses tables. The script below will store data into a new database called user.dbĬur.execute( "CREATE TABLE Users(Id INT, Name TEXT)")Ĭur.execute( "INSERT INTO Users VALUES(1,'Michelle')")Ĭur.execute( "INSERT INTO Users VALUES(2,'Sonya')")Ĭur.execute( "INSERT INTO Users VALUES(3,'Greg')") Which in turn returned its version number. It then queries the database management system with the command The script connected to a new database called test.db with this line: Copy this program and save it as test1.py Install SQLite:Use this command to install SQLite: The SQLite project is sponsored by Bloomberg and Mozilla. It is a self-contained, serverless, zero-configuration, transactional SQL database engine. The source code for SQLite is in the public domain. SQLite is the most widely deployed SQL database engine in the world. SQLite, a relational database management system. The language has been around since 1986 and is worth learning. SQL is a special-purpose programming language designed for managing data held in a databases. SQLite was created in the year 2000 and is one of the many management systems in the database zoo. One of these database management systems (DBMS) is called SQLite. Python has bindings for many database systems including MySQL, Postregsql, Oracle, Microsoft SQL Server and Maria DB. Data is either in memory, files or databases. Data is everywhere and software applications use that. Data is retrieved from a database system using the SQL language. You will learn how to use SQLite, SQL queries, RDBMS and more of this cool stuff!
