My poor use of golang's defer woke me up(blog.daemonl.com)

    err = db.QueryRow(`...`, ...).Scan(&...)
    if err == sql.ErrNoRows {
    	// Handle no rows
    } else if err != nil {
    	// Handle actual error
    }
    // All fine

    rows, err := db.Query(`...`, ...)
    if err != nil {
    	// Handle connection or statement error
    }
    defer rows.Close()
    
    things := []rowStruct{}
    for rows.Next() {
    	thing := rowStruct{}
    	err = rows.Scan(
    		&thing.id,
    		&thing.value,
    	)
    	if err != nil {
    		// Handle row parsing error
    	}
    
    	things = append(things, thing)
    }
    err = rows.Err()
    if err != nil {
    	// Handle any errors within rows
    }
    rows.Close()

    rows, err := db.Query(`...`,...)
    if err != nil {
    	// Handle connection or statement error
    }
    defer func() {
    	log.Println(`Closing rows`)
    	rows.Close()
    }()
