# querify
Query your data from and to any json compatible source.
The query language used is similar to SQL with Postgres dialect.
```go
hobbiesTable := []map[string]interface{}{
{"id": 1, "name": "Football"},
{"id": 2, "name": "Basketball"},
{"id": 3, "name": "Hockey"},
}
usersTable := []map[string]interface{}{
{"id": 1, "name": "Max"},
{"id": 2, "name": "Tom"},
{"id": 3, "name": "Alex"},
}
userHobbiesTable := []map[string]interface{}{
{"user_id": 1, "hobby_id": 1},
{"user_id": 1, "hobby_id": 2},
{"user_id": 2, "hobby_id": 3},
{"user_id": 3, "hobby_id": 1},
}
type User struct {
Name string
Hobbies []string
}
var users []User
err := querify.From(usersTable).As("users").
Join(
querify.LeftJoin{
Right: querify.From(userHobbiesTable).As("user_hobbies"),
On: querify.Equals{querify.Ident("users.id"), querify.Ident("user_hobbies.user_id")},
},
querify.LeftJoin{
Right: querify.From(hobbiesTable).As("hobbies"),
On: querify.Equals{querify.Ident("hobbies.id"), querify.Ident("user_hobbies.hobby_id")},
},
).
GroupBy(querify.Ident("users.name")).
Select(
querify.As{
Name: "name",
Expression: querify.Ident("users.name"),
},
querify.As{
Name: "hobbies",
Expression: querify.ArrayAgg{
Expression: querify.Ident("hobbies.name"),
},
},
).Scan(&users)
if err != nil {
panic(err)
}
fmt.Println(users)
// [{Max [Football Basketball]} {Tom [Hockey]} {Alex [Football]}]
