C++ Database CRUD

Building a CRUD App

C++ database CRUD with SQLite handles data operations.

Introduction to SQLite with C++

SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. In this guide, we will learn how to perform CRUD (Create, Read, Update, Delete) operations using C++ with SQLite.

Setting Up SQLite in a C++ Project

Before you can use SQLite in your C++ project, you need to set up the SQLite library. You can download the SQLite amalgamation source from the official SQLite website and include it in your project. For simplicity, we will assume that you have already integrated SQLite in your development environment.

Creating a Table

To create a table in SQLite using C++, you will use SQL commands executed through the SQLite API. Below is an example of creating a simple table named users.

Inserting Data into Table

Once the table is created, you can insert data into it. This involves executing an SQL INSERT statement using the SQLite API.

Reading Data from Table

Reading data from a table involves executing a SELECT query. The result of the query is processed using callback functions.

Updating Data in Table

Updating existing records in the table is done using the UPDATE SQL statement.

Deleting Data from Table

To delete records from a table, you will use the SQL DELETE statement. Below is an example of deleting a record based on a condition.

Conclusion

In this tutorial, we covered the basics of performing CRUD operations using C++ with SQLite. These fundamentals provide a solid foundation for building more complex database applications.
