# point

This sample module shows how to create a type that implements the required interfaces to be used as a custom type with [github.com/jmoiron/sqlx](github.com/jmoiron/sqlx) package.

Sample db table:

```
CREATE TABLE places (id SERIAL, name varchar(512), loc point);
```

and then use as such (err omitted for brevity):


```
type Location struct {
	Id          int
	Name        string
	Description string
	Loc         Point // custom type
}

func main() {
	db, _ := sqlx.Connect(
		"postgres",
		"<your config here>",
	)

	loc := Location{}
	rows, _ := db.Queryx(
		`SELECT * FROM places`,
	)
	for rows.Next() {
		rows.StructScan(&loc)
		fmt.Printf("%+v", loc)
	}

	db.Exec(
		"INSERT INTO places(name, loc) VALUES ($1, $3):,
		"some name"
		Point{3.14, 6.28},
	)
}
```
