How do I use the SELECT statement in Go?

To use the SELECT statement in Go, you typically use the database/sql package. First, you need to import it and establish a connection to your database.

Can you show me a code example?

Sure! Here's a simple example:

package main

import (
    "database/sql"
    _ "github.com/lib/pq"
    "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 filter the results?

You can add a WHERE clause to your SELECT statement. For example:

rows, err := db.Query("SELECT id, name FROM users WHERE age > $1", 18)
