# SQLite [![Version][version-img]][version-url] [![Status][status-img]][status-url]
|
|
|
|
The package provides an interface to [SQLite][1].
|
|
|
|
## [Documentation][doc]
|
|
|
|
## Example
|
|
|
|
```rust
|
|
let connection = sqlite::open(":memory:").unwrap();
|
|
|
|
connection.execute("
|
|
CREATE TABLE `users` (id INTEGER, name VARCHAR(255));
|
|
INSERT INTO `users` (id, name) VALUES (42, 'Alice');
|
|
").unwrap();
|
|
|
|
connection.process("SELECT * FROM `users`", |pairs| {
|
|
for &(column, value) in pairs.iter() {
|
|
println!("{} = {}", column, value.unwrap());
|
|
}
|
|
true
|
|
}).unwrap();
|
|
```
|
|
|
|
The same example using prepared statements:
|
|
|
|
```rust
|
|
use sqlite::State;
|
|
|
|
let connection = sqlite::open(":memory:").unwrap();
|
|
|
|
connection.execute("
|
|
CREATE TABLE `users` (id INTEGER, name VARCHAR(255))
|
|
");
|
|
|
|
let mut statement = connection.prepare("
|
|
INSERT INTO `users` (id, name) VALUES (?, ?)
|
|
").unwrap();
|
|
statement.bind(1, 42).unwrap();
|
|
statement.bind(2, "Alice").unwrap();
|
|
assert_eq!(statement.step().unwrap(), State::Done);
|
|
|
|
let mut statement = connection.prepare("SELECT * FROM `users`").unwrap();
|
|
while let State::Row = statement.step().unwrap() {
|
|
println!("id = {}", statement.read::<i64>(0).unwrap());
|
|
println!("name = {}", statement.read::<String>(1).unwrap());
|
|
}
|
|
```
