How do I execute SQL queries using the Go SQL package?

To execute SQL queries in Go, you can use the database/sql package along with a driver for your database.

Can you show me a simple example of executing a SELECT query?

Sure! Here's a basic example:

package main

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

func main() {
    db, err := sql.Open("postgres", "user=username dbname=mydb sslmode=disable")
    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 execute an INSERT query?

For an INSERT query, you can use the Exec method. Here's an example:

_, err := db.Exec("INSERT INTO users(name) VALUES($1)", "John Doe")
if err != nil {
    log.Fatal(err)
}
