How do I use the Go SQL driver for database queries?

To use the Go SQL driver, you first need to import the database/sql package and the specific driver for your database.

Can you show me a simple example of querying a database?

Sure! Here's a basic example:

package main

import (
    "database/sql"
    _ "github.com/go-sql-driver/mysql"
    "log"
)

func main() {
    db, err := sql.Open("mysql", "user:password@/dbname")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    rows, err := db.Query("SELECT id, name FROM users")
    if err != nil {
        log.Fatal(err)
    }
    defer rows.Close()

    for rows.Next() {
        var id int
        var name string
        if err := rows.Scan(&id, &name); err != nil {
            log.Fatal(err)
        }
        log.Println(id, name)
    }
} 

What if I want to insert data into the database?

You can use the Exec method for inserting data. Here's an example:

stmt, err := db.Prepare("INSERT INTO users(name) VALUES(?)")
if err != nil {
    log.Fatal(err)
}
res, err := stmt.Exec("John Doe")
if err != nil {
    log.Fatal(err)
}
