That makes it a user-friendly option for learning database application development.Īnother advantage of using SQLite is that the library comes shipped with Python and also with PyQt, so you don’t need to install anything else to start working with it. SQLite allows you to read and write directly to databases in your local disk without the need for a separate server process. In this tutorial, you’ll use SQLite 3, which is a well-tested database system with support on all platforms and minimal configuration requirements. To perform this step successfully, you need some general information about how your database is set up.įor example, you need to know what database management system your database is built on, and you might also need to have a username, a password, a hostname, and so on. Remove ads Creating a Database ConnectionĬonnecting your applications to a physical SQL database is an important step in the process of developing database applications with PyQt. You can connect Python to any of these database systems using a dedicated Python SQL library. You’ll find several different database management systems, such as SQLite, PostgreSQL, MySQL, MariaDB, and many others. Relational database systems and SQL are widely used nowadays. SQL is a declarative and domain-specific programming language specially designed for communicating with databases. Most relational database systems use SQL (structured query language) for querying, manipulating, and maintaining the data held in the database. For example, in a database that stores data about the employees in a company, a specific row represents an individual employee.
Each row represents a set of closely related data, and every row has the same general structure. On the other hand, the term field name is used to identify the name of a column.Įach column stores a specific kind of information, such as a names, dates, or numbers. Where is the problem? I'm not sure if this is relevant but my table view is on qwidget which is on tab widget.Note: The term field is commonly used to identify a single piece of data stored in a cell of a given record in a table. The method insertData inside my custom model TableModel gets called but data does not get changed (new rows are added). I want to update table view data with setData method when the push button is pressed. I went through previous questions on stackoverflow regarding updating table view and Qt tutorial but I still cannot get my code to work.
