Create SQL dumps in Go without external dependencies

Go MYSQL Dump

Create MYSQL dumps in Go without the mysqldump CLI as a dependancy.

Simple Example

package main

import (
	"database/sql"
	"fmt"

	"github.com/go-sql-driver/mysql"
	"github.com/writeas/go-mysqldump"
)

func main() {
	// Open connection to database
	config := mysql.NewConfig()
	config.User = "your-user"
	config.Passwd = "your-pw"
	config.DBName = "your-db"
	config.Net = "tcp"
	config.Addr = "your-hostname:your-port"

	// Directory to create database dumps in
	dumpDir := "dumps"
	// This accepts time layout string and will add .sql at the end of filename
	dumpFilenameFormat := fmt.Sprintf("%s-20060102T150405", config.DBName)

	db, err := sql.Open("mysql", config.FormatDSN())
	if err != nil {
		fmt.Println("Error opening database: ", err)
		return
	}

	// Register database with mysqldump
	dumper, err := mysqldump.Register(db, dumpDir, dumpFilenameFormat)
	if err != nil {
		fmt.Println("Error registering databse:", err)
		return
	}

	// Dump database to file
	err := dumper.Dump()
	if err != nil {
		fmt.Println("Error dumping:", err)
		return
	}
	fmt.Printf("File is saved to %s", dumpFilenameFormat)

	// Close dumper, connected database and file stream.
	dumper.Close()
}
