Initializing the project with CargoĬargo makes it easier to start a Rust project of any kind. As lightweight and “pruned” as it sounds, it has most of the important query language features in the SQL2 standards. SQLite transactions are ACID-compliant (atomic, consistent, isolated, and durable), providing safe access to multi-threading operations. Because SQLite is literally a database residing in a single cross-platform file, it requires no administration. It is serverless and requires zero configurations. SQLite is a relational database management system with a lightweight feel in terms of setup complexity and resource usage. Ability to start a development project in your preferred environment.Basic understanding of database connections.Familiarity with the Rust programming language and Cargo build system and package manager.To follow along with this tutorial, you’ll need the following: Getting familiar with the Diesel framework.Getting familiar with the Rocket framework.Connecting to the SQLite database with Rust.We’ll create a SQLite database, set up and install the Rocket framework for writing the server logic, and then use the Diesel framework to handle connections to the SQLite database. This tutorial will demonstrate how to use SQLite as the database context system for Rust APIs. SQLite and Rust will provide you with speed and efficiency. When the above program is executed, it will create the given records in the COMPANY table and will display the following two lines.Whether you’re using SQLite because it is the most popular database engine in the world, or you’re working with Rust because it is the most loved language, you can never go wrong with these two technologies. When the above program is executed, it will create the COMPANY table in your test.db and it will display the following messages −įollowing PHP program shows how to create records in the COMPANY table created in the above example. If the database is successfully created, then it will display the following message −įollowing PHP program will be used to create a table in the previously created database. You can change your path as per your requirement. Now, let's run the above program to create our database test.db in the current directory. If database does not exist, then it will be created and finally a database object will be returned. Connect to Databaseįollowing PHP code shows how to connect to an existing database. This routine returns a string that has been properly escaped for safe inclusion in an SQL statement. Public string SQLite3::escapeString ( string $value ) This routine closes a database connection previously opened by a call to SQLite3::open(). This routine returns the number of database rows that were updated, inserted, or deleted by the most recent SQL statement. This routine returns English text describing the most recent failed SQLite request. Public string SQLite3::lastErrorMsg ( void ) This routine returns the numeric result code of the most recent failed SQLite request. Public int SQLite3::lastErrorCode ( void ) This routine executes an SQL query, returning an SQLite3Result object if the query returns results. Public SQLite3Result SQLite3::query ( string $query ) This routine is used to execute a result-less query against a given database. This routine provides a quick, easy way to execute SQL commands provided by sql argument, which can consist of more than one SQL command. Public bool SQLite3::exec ( string $query ) By default, open uses SQLITE3_OPEN_READWRITE | SQLITE3_OPEN_CREATE. Optional flags used to determine how to open the SQLite database. If no file by that name exists, then a new database file by that name gets created. If the filename is actual device file name, SQLite3::open() attempts to open the database file by using its value. If the filename is given as ':memory:', SQLite3::open() will create an in-memory database in RAM that lasts only for the duration of the session. If the build includes encryption, then it will attempt to use the key. Public void SQLite3::open ( filename, flags, encryption_key )
