# SQLite [![Package][package-img]][package-url] [![Documentation][documentation-img]][documentation-url] [![Build][build-img]][build-url]
The package provides an interface to [SQLite].
## Example
Open a connection, create a table, and insert a few rows:
```rust
let connection = sqlite::open(":memory:").unwrap();
connection
.execute(
"
CREATE TABLE users (name TEXT, age INTEGER);
INSERT INTO users VALUES ('Alice', 42);
INSERT INTO users VALUES ('Bob', 69);
",
)
.unwrap();
```
Select some rows and process them one by one as plain text:
```rust
connection
.iterate("SELECT * FROM users WHERE age > 50", |pairs| {
for &(column, value) in pairs.iter() {
println!("{} = {}", column, value.unwrap());
}
true
})
.unwrap();
```
Run the same query but using a prepared statement, which is much more efficient
than the previous technique:
```rust
use sqlite::State;
let mut statement = connection.prepare("SELECT * FROM users WHERE age > ?").unwrap();
statement.bind(1, 50).unwrap();
while let Ok(State::Row) = statement.next() {
println!("name = {}", statement.read::<String>(0).unwrap());
println!("age = {}", statement.read::<i64>(1).unwrap());
}
```
Run the same query but using a cursor, which is a wrapper around a prepared
statement providing the notion of row and featuring all-at-once binding:
```rust
use sqlite::Value;
let cursor = connection
.prepare("SELECT * FROM users WHERE age > ?")
.unwrap()
.into_cursor()
.bind(&[50.into()])
.unwrap();
println!("age = {}", row.get::<i64, _>("age"));
}
```
