# Distinct with Query

> Fetch distinct values for a field based on a query filter using API Maker's g.sys.db.distinctWithQuery method.

Source: https://docs.apimaker.dev/v4/examples/sys/db/distinctQuery.html

> **The code in every language**
>
> Each example is the inside of `main`, written in every [language](https://docs.apimaker.dev/v4/docs/languages/index.html) API Maker runs : pick yours in the tabs, and every page shows it from then on. The types a call takes (`GetAll`, `DeepItem`…) are those of `am` : `from am import GetAll` in Python, `use am::GetAll;` in Rust, `import am.GetAll;` in Java and Kotlin ; PHP and C# have them without an import, Go names them `am.GetAll`.

`g.sys.db.distinctQuery` calls the [distinct with query schema API](https://docs.apimaker.dev/v4/docs/apis-all/schema-apis/auto-generated-schema-based-distinct-with-query-api.html) of any table from your code, with the same headers and query parameters as over HTTP. It returns the data. The whole envelope (`success`, `statusCode`, `data`, `totalCount`, `errors`…) comes back when `true` is passed as the second argument in TypeScript, and through `full` in the other languages : `g.sys.db.full` (`g.Sys.Db.Full` in C# and Go, `$g->sys->db->full` in PHP).

## Multi-tenant
- `instance: "crm::acme"` works on the database of the tenant `acme` of the [multi-tenant](https://docs.apimaker.dev/v4/docs/features/multi-tenant.html) instance `crm`.
- With `instance: "crm"`, the call works on the database of the tenant of the request: a custom API called with the [x-am-tenant-username](https://docs.apimaker.dev/v4/docs/apis-all/header/requestHeader.html#x-am-tenant-username) header passes it on to the APIs it calls. A request without a tenant works on the structure database.

**TypeScript**

**Distinct first names of some customers of the tenant acme**

```typescript
let distinctQuery = await g.sys.db.distinctQuery({
    instance: "crm::acme", database: "crm", collection: "customers",
    distinctField: "first_name",
    find: {
        "last_name": "Lin"
    }
});

    'first_name',
    find={
        'last_name': 'Lin',
    },
)
```

**PHP**

        .find(json!({
            "last_name": "Lin",

```

**Java**

**Distinct first names of some customers of the tenant acme**

```java

    .find(Map.of(
        "last_name", "Lin"

**Kotlin**

**Distinct first names of some customers of the tenant acme**

```kotlin

            "last_name" to "Lin",

## Without a schema

`g.sys.db.gen.distinctQueryGen` takes the same arguments and calls the [distinct with query generated API](https://docs.apimaker.dev/v4/docs/apis-all/schema-apis/auto-generated-schema-based-distinct-with-query-api.html#without-a-schema) : no schema, so the data is read and written as it is in the table, without the conversions, validations and defaults of the schema.

| Language | The call |
|---|---|
| TypeScript | `g.sys.db.gen.distinctQueryGen(…)` |
| Python | `g.sys.db.gen.distinct_query_gen(…)` |
| PHP | `$g->sys->db->gen->distinctQueryGen(…)` |
| C#, Go | `g.Sys.Db.Gen.DistinctQueryGen(…)` |
| Rust | `g.sys.db.distinct_query_gen(Distinct::new(…))` |
| Java, Kotlin | `g.sys.db.gen.distinctQueryGen(…)` |
