Swift-Kuery-SQLite

SQLite plugin for the Swift-Kuery framework. It enables you to use Swift-Kuery to manipulate data in an SQLite database.

SQLite installation

To use Swift-Kuery-SQLite you must install SQLite.

macOS

You can install SQLite with Homebrew:

$ brew install sqlite

Or, if you prefer MacPorts, you can use that too, though note that you need to symlink a file into the place that Homebrew installs it:

$ port install sqlite3
$ mkdir -p /usr/local/opt/sqlite/include
$ ln -s /opt/local/include/sqlite3.h /usr/local/opt/sqlite/include/

Linux

$ sudo apt-get install sqlite3 libsqlite3-dev

Usage

Add dependencies

Add the Swift-Kuery-SQLite package to the dependencies within your application’s Package.swift file. Substitute "x.x.x" with the latest Swift-Kuery-SQLite release.

.package(url: "https://github.com/IBM-Swift/Swift-Kuery-SQLite.git", from: "x.x.x")

Add SwiftKuerySQLite to your target’s dependencies:

.target(name: "example", dependencies: ["SwiftKuerySQLite"]),

Import package

  import SwiftKuerySQLite

Using Swift-Kuery-SQLite

First create an instance of Swift-Kuery-SQLite by calling:

let connection = SQLiteConnection(filename: "myDB.db")

You don’t have to pass a filename, if you choose not to pass in a filename then your database will be in-memory.

To establish a connection call:

connection.connect(onCompletion: (QueryError?) -> ())

If you want to have multiple connections to your database you can create a ConnectionPool as follows:

let pool = SQLiteConnection.createPool(filename: "myDB.db", poolOptions: ConnectionPoolOptions(initialCapacity: 10, maxCapacity: 30, timeout: 10000))

let connection = pool.getConnection()

Note, you don’t have to pass a filename to the createPool method, if you choose not to pass in a filename then your pool will be shared in-memory.

You now have a connection that can be used to execute SQL queries created using Swift-Kuery. View the Kuery documentation for more information, or see the Database Connectivity with Kuery chapter of the Kitura Until Dawn guidebook/tutorial.
