The package provides an interface to [SQLite].
Open a connection, create a table, and insert some 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();
The same query 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() .bind(1, 50) .unwrap();
while let Ok(State::Row) = statement.next() {
println!("name = {}", statement.read::
The same query 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 mut cursor = connection .prepare("SELECT * FROM users WHERE age > ?") .unwrap() .into_cursor() .bind(&[Value::Integer(50)]).unwrap();
while let Some(Ok(row)) = cursor.next() {
println!("name = {}", row.get::
