Single-Player Database Development Tutorial Video312

Developing single-player database applications is a great way to learn about database design and development. In this tutorial, we'll walk you through the process of creating a simple database application from scratch, using the SQLite database engine. We'll cover everything from creating a database and tables to inserting, updating, and deleting data.

Prerequisites

To complete this tutorial, you will need the following:
A text editor
The SQLite database engine
A basic understanding of SQL

Creating a Database

The first step in developing a database application is to create a database. In SQLite, you can create a database by simply opening a new file with a .db extension. For example, to create a database called "", you would open a new file named "" in your text editor.

Creating Tables

Once you have created a database, you need to create tables to store your data. A table is a collection of rows and columns, and each row represents a single record in your database. To create a table, you use the CREATE TABLE statement. For example, to create a table called "users" with three columns ("id", "name", and "email"), you would use the following statement:```sql
CREATE TABLE users (
id INTEGER PRIMARY KEY,
name TEXT,
email TEXT
);
```

Inserting Data

Once you have created a table, you can insert data into it using the INSERT INTO statement. For example, to insert a new row into the "users" table, you would use the following statement:```sql
INSERT INTO users (name, email) VALUES ('John Doe', '@');
```

Updating Data

You can update data in a table using the UPDATE statement. For example, to update the email address of the user with the ID of 1, you would use the following statement:```sql
UPDATE users SET email = '@' WHERE id = 1;
```

Deleting Data

You can delete data from a table using the DELETE statement. For example, to delete the user with the ID of 1, you would use the following statement:```sql
DELETE FROM users WHERE id = 1;
```

Conclusion

This tutorial has provided a basic overview of how to develop single-player database applications using the SQLite database engine. We've covered everything from creating a database and tables to inserting, updating, and deleting data. For more information, please consult the SQLite documentation.
