The package provides an interface to SQLite.

Documentation

Example

Open a connection, create a table, and insert a couple of rows:

```rust let connection = sqlite::open(":memory:").unwrap();

connection.execute(" CREATE TABLE users (name TEXT, age INTEGER); INSERT INTO users (name, age) VALUES ('Alice', 42); INSERT INTO users (name, age) VALUES ('Bob', 69); ").unwrap(); ```

Select a row from the table:

rust connection.iterate("SELECT * FROM users WHERE age > 50", |pairs| { for &(column, value) in pairs.iter() { println!("{} = {}", column, value.unwrap()); } true }).unwrap();

The same query using a prepared statement:

```rust use sqlite::State;

let mut statement = connection.prepare(" SELECT * FROM users WHERE age > ? ").unwrap();

statement.bind(1, 50).unwrap();

while let State::Row = statement.next().unwrap() { println!("name = {}", statement.read::(0).unwrap()); println!("age = {}", statement.read::(1).unwrap()); } ```

The same query using a cursor, which is a wrapper around a prepared statement:

```rust use sqlite::Value;

let mut cursor = connection.prepare(" SELECT * FROM users WHERE age > ? ").unwrap().cursor();

cursor.bind(&[Value::Integer(50)]).unwrap();

while let Some(row) = cursor.next().unwrap() { println!("name = {}", row[0].asstring().unwrap()); println!("age = {}", row[1].asinteger().unwrap()); } ```
