Overview

Package array provides the array table-valued SQL function.

Example

db, err := driver.Open(":memory:", func(c *sqlite3.Conn) error {
	array.Register(c)
	return nil
})
if err != nil {
	log.Fatal(err)
}
defer db.Close()

rows, err := db.Query(`
		SELECT name
		FROM pragma_function_list
		WHERE name like 'geopoly%' AND narg IN array(?)`,
	sqlite3.Pointer([]int{2, 3, 4}))
if err != nil {
	log.Fatal(err)
}
defer rows.Close()

for rows.Next() {
	var name string
	err := rows.Scan(&name)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("%s\n", name)
}
if err := rows.Err(); err != nil {
	log.Fatal(err)
}

Output:

geopoly_regular
geopoly_overlap
geopoly_contains_point
geopoly_within
