示例代码:
import SQLite let db = Database("path/to/db.sqlite3") db.execute( "CREATE TABLE users (" + "id INTEGER PRIMARY KEY, " + "email TEXT NOT NULL UNIQUE, " + "manager_id INTEGER, " + "FOREIGN KEY(manager_id) REFERENCES users(id)" + ")" ) let stmt = db.prepare("INSERT INTO users (email) VALUES (?)") for email in ["alice@example.com", "betsy@example.com"] { stmt.run(email) } db.totalChanges // 2 db.lastChanges // {Some 1} db.lastID // {Some 2} for row in db.prepare("SELECT id, email FROM users") { println(row) // [Optional(1), Optional("betsy@example.com")] // [Optional(2), Optional("alice@example.com")] } db.scalar("SELECT count(*) FROM users") // {Some 2} let jr = db.prepare("INSERT INTO users (email, manager_id) VALUES (? ?)") db.transaction( stmt.run("dolly@example.com"), jr.run("emery@example.com", db.lastID) )
