如何利用MySQL和Go語言發展一個簡單的日程提醒系統
#隨著現代生活的快節奏和工作的繁忙,我們常常忽略了重要的事情和約會。為了幫助人們更好地管理時間,我們可以利用MySQL和Go語言來發展一個簡單的日程提醒系統。本文將介紹如何透過MySQL資料庫儲存日程信息,並使用Go語言編寫相關程式碼。
首先,我們需要設計一個資料庫來儲存行程資訊。我們可以建立一個名為"events"的表,包含以下欄位:
CREATE TABLE events ( id INT AUTO_INCREMENT PRIMARY KEY, title VARCHAR(255) NOT NULL, date DATE NOT NULL, time TIME NOT NULL, description TEXT );
package main import ( "database/sql" "fmt" "log" _ "github.com/go-sql-driver/mysql" )
type Event struct { ID int Title string Date string Time string Description string }
func getEvents(db *sql.DB) ([]Event, error) { rows, err := db.Query("SELECT * FROM events") if err != nil { return nil, err } defer rows.Close() var events []Event for rows.Next() { var event Event err := rows.Scan(&event.ID, &event.Title, &event.Date, &event.Time, &event.Description) if err != nil { return nil, err } events = append(events, event) } if err = rows.Err(); err != nil { return nil, err } return events, nil }
func createEvent(db *sql.DB, event Event) (int64, error) { stmt, err := db.Prepare("INSERT INTO events (title, date, time, description) VALUES (?, ?, ?, ?)") if err != nil { return -1, err } defer stmt.Close() result, err := stmt.Exec(event.Title, event.Date, event.Time, event.Description) if err != nil { return -1, err } id, err := result.LastInsertId() if err != nil { return -1, err } return id, nil }
func main() { db, err := sql.Open("mysql", "user:password@tcp(localhost:3306)/database") if err != nil { log.Fatal(err) } defer db.Close() events, err := getEvents(db) if err != nil { log.Fatal(err) } for _, event := range events { fmt.Println(event.Title, event.Date, event.Time, event.Description) } event := Event{ Title: "Meeting", Date: "2021-01-01", Time: "10:00:00", Description: "Important meeting with clients", } id, err := createEvent(db, event) if err != nil { log.Fatal(err) } fmt.Println("Created event with ID:", id) }
