Data is sent to and received from the MySQL server in its native data type without converting to and from strings. +A Swift wrapper for MySQL. + +- [x] Thread-Safe +- [x] Prepared Statements +- [x] Tested + +This wrapper uses the latest MySQL fetch API to enable performant prepared statements and output bindings. Data is sent to and received from the MySQL server in its native data type without converting to and from strings. The Swift wrappers around the MySQL's C structs and pointers automatically manage closing connections and deallocating memeory. Additionally, the MySQL library API is used to perform thread safe, performant queries to the database. ~40 assertions tested on Ubuntu 14.04 and macOS 10.11 on every push. +## 📖 Examples + +### Connecting to the Database + +```swift +import MySQL + +let mysql = try MySQL.Database( + host: "127.0.0.1", + user: "root", + password: "", + database: "test" +) +``` + +### Select + +```swift +let version = try mysql.execute("SELECT @@version") +``` + +### Prepared Statement + +The second parameter to `execute()` is an array of `MySQL.Value`s. + +```swift +let results = try mysql.execute("SELECT * FROM users WHERE age >= ?", [.int(21)]) +``` + +```swift +public enum Value { + case string(String) + case int(Int) + case uint(UInt) + case double(Double) + case null +} +``` + +### Connection + +Each call to `execute()` creates a new connection to the MySQL database. This ensures thread safety since a single connection cannot be used on more than one thread. + +If you would like to re-use a connection between calls to execute, create a reusable connection and pass it as the third parameter to `execute()`. + +```swift +let connection = msyql.makeConnection() +let result = try mysql.execute("SELECT LAST_INSERTED_ID() as id", [], connection) +``` + +No need to worry about closing the connection. + +## 🚀 Building + +### macOS + +Install MySQL + +```shell +brew install mysql +brew link mysql +mysql.server start +``` + +Use `vapor build` or manually link MySQL during `swift build` with + +```swift +swift build -Xswiftc -I/usr/local/include/mysql -Xlinker -L/usr/local/lib +``` + +`-I` tells the compiler where to find the MySQL header files, and `-L` tells the linker where to find the library. This is required to compile and run on macOS. + +### Linux + +Install MySQL + +```shell +sudo apt-get update +sudo apt-get install -y mysql-server libmysqlclient-dev +sudo mysql_install_db +sudo service mysql start +``` + +Use `vapor build`. `swift build` should also work normally. + ## 📖 Documentation Visit the Vapor web framework's [documentation](http://docs.vapor.codes) for instructions on how to use this package.
