var schema = `Create table person2(

var schema2 = `Create table place(

type Person struct {

type Place struct {

func main() {

    db, err := sqlx.Connect("mysql", dsn)
    if err != nil {
        panic(err)
    }

    result, err := db.Exec(schema2)
    if err != nil {
        panic(err)
    }
    _, err = result.RowsAffected()
    if err != nil {
        panic(err)
