How to share mysql connection using sqlx?

I'd like to share sqlx connection to be used in other functions. Here is what I came up with:

 var dbmap = initDb()
    
 func initDb() *sqlx.DB {         
    	db, err := sqlx.Connect("mysql", "myuser:mypasswd@tcp(127.0.0.1:3306)/mydb")        
    	if err != nil {
    		log.Fatalln(err)
    	}        
    	// defer db.Close()        
    	return db
    }

And then in functions I'd like to make queries like:

var users []User
err := dbmap.Get(&users, "SELECT * FROM user")

However I get panic:

scannable dest type slice with >1 columns (3) in result

What's wrong here? How can I fix it?

Error message says pretty much everything :). Get() method is not intended to scan into slice, use Select() instead
