如何在MySQL的Golang GORM中从查询中提取数据?

I'm trying to read the data from a database with GoLang's GORM, and am new to Go in general. This is the snippet I'm trying to get work. It's to search a database using a number and check if it already exists. Just grasping at straws here, and not really understanding how GORM works, and can't find documentation that explains what to do after doing a Where Clause.

res := db.Where("Number = ?", inumber).First(&Profile{})
log.Print("Searched for profile")
if res.RecordNotFound() {
    log.Print("Record not found")
    return "", "", "", false
} else {

    ret := res.Scan(&Profile{})

    You need to retrieve data into some variable to be able to use it later:

    p := Profile{}
    res := db.Where("Number = ?", inumber).First(&p)
    // now use p
    log.Printf("%+v", p)
