How can I use Go with different database systems?

What are the best database systems to use with Go?

Some popular database systems to use with Go include PostgreSQL, MySQL, MongoDB, and SQLite.

How do I connect to a PostgreSQL database using Go?

You can use the "github.com/lib/pq" driver to connect to PostgreSQL. Here's a simple example:

import (
    "database/sql"
    _ "github.com/lib/pq"
)

func main() {
    connStr := "user=username dbname=mydb sslmode=disable"
    db, err := sql.Open("postgres", connStr)
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()
}

What about using MongoDB with Go?

For MongoDB, you can use the "go.mongodb.org/mongo-driver/mongo" package. Here's a quick example:

import (
    "context"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

func main() {
    clientOptions := options.Client().ApplyURI("mongodb://localhost:27017")
    client, err := mongo.Connect(context.TODO(), clientOptions)
    if err != nil {
        log.Fatal(err)
    }
    defer client.Disconnect(context.TODO())
}
