![]() ![]() In this section, we will add the data structure to our newly created people.db database by creating a student table. How to use SQLite's CREATE TABLE command. SQLite works well with Python because the Python standard library provides the sqlite3 module, which you can use to interact with any SQLite database without having to install anything. With your databases created and connections verified, you can begin introducing data structure to your database(s). SQLite is a simple and fast open source SQL engine that can be used with Python to store and manipulate application data. In this way, the Python file writes to and the SQLite shell reads from. Creating tables within a database in SQLite. Table of Contents sqlite3 DB-API 2. If you work in Windows, I think it might be useful to move this sqlite.exe file to same folder with the other Python files. To list the tables in an SQLite database file, you can use the following command in the SQLite command-line shell: This command lists the names of all tables. It is great for learning and tutorials, but not good for real-life applications. To see all tables in the database you have previously chosen, type the command. In other words use "c:/work/ex1.db", not "c:\work\ex1.db". sqlquery '''SELECT name FROM sqlitemaster WHERE type'table' ''' 3. Created one SQLite query with which we will search a list of all tables which are present inside the sqlite3 database. Use forward-slashes as the directory separator character. Creating a connection object using connect () method, sqliteConnection nnect ('SQLiteRetrievingdata.db') 2. DB4S uses a familiar spreadsheet-like interface, and complicated SQL commands do not have to be learned. DB4S is for users and developers who want to create, search, and edit databases. You might want to use a full pathname to ensure that the file is in the directory that you think it is in. What it is DB Browser for SQLite (DB4S) is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite. The example above causes the database file named "ex1.db" to be opened and used, and created if it does not previously exist. The schema for a database is a description of all of the other tables, indexes, triggers, and views that are contained within the database. To use a persistent disk file as the database, enter the ".open ex1.db" command immediately after the terminal window starts up. Every SQLite database contains a single 'schema table' that stores the schema for that database. When it is initialized, by default this SQLite session is using an in-memory database, not a file on disk, and so all changes will be lost when the session exits. ![]() Besides, if you are using Windows OS and do not know where the command shell is, that is in the SQLite's site:Īfter downloading it, click sqlite3.exe file to initialize the SQLite command shell. You can manipulate your database using the commands described in this link. Since nobody has mentioned about the official reference of SQLite, I think it may be useful to refer to it under this heading:
