如何在kitura应用程序中调用mysql存储过程

import Kitura
import MySQL

// 创建MySQL连接实例
let mysql = MySQL()

// 连接到MySQL数据库
guard mysql.connect(host: "localhost", user: "username", password: "password", database: "database") else {
    print("连接到MySQL数据库失败：\(mysql.errorMessage())")
    return
}

// 创建MySQL连接对象
let connection = mysql.connection!

// 打开MySQL连接
guard connection.open() else {
    print("打开MySQL连接失败：\(mysql.errorMessage())")
    return
}

// 构建调用存储过程的SQL语句
let procedureName = "your_procedure_name"
let sql = "CALL \(procedureName)();"

// 执行SQL语句
guard connection.query(statement: sql) else {
    print("执行SQL语句失败：\(mysql.errorMessage())")
    return
}

// 处理结果
let results = connection.storeResults()
while let row = results?.next() {
    // 处理每一行结果
    let column1 = row[0] ?? ""
    let column2 = row[1] ?? ""
    // ...
}

// 关闭连接
connection.close()
