# Get by ID

> Retrieve a single record from a collection based on its unique identifier using API Maker's g.sys.db.getById method.

Source: https://docs.apimaker.dev/v4/examples/sys/db/getById.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.getById` calls the [get by id schema API](https://docs.apimaker.dev/v4/docs/apis-all/schema-apis/auto-generated-schema-based-get-by-id-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**

**Get the customer 1 of the tenant acme**

```typescript
let getById = await g.sys.db.getById({
    instance: "crm::acme", database: "crm", collection: "customers",
    id: 1
});
```

**Python**

**Get the customer 1 of the tenant acme**

```python
get_by_id = await g.sys.db.get_by_id(
    'crm::acme', 'crm', 'customers',
    1,
)
```

**PHP**

**Get the customer 1 of the tenant acme**

```php
$getById = $g->sys->db->getById(
    'crm::acme', 'crm', 'customers',
    1,
);
```

**C#**

**Get the customer 1 of the tenant acme**

```csharp
var getById = await g.Sys.Db.GetById(new GetById("crm::acme", "crm", "customers", 1));
```

**Go**

**Get the customer 1 of the tenant acme**

```go
getById, err := g.Sys.Db.GetById(am.GetById{
	Instance: "crm::acme", Database: "crm", Collection: "customers",
	Id: 1,
})
if err != nil {
	return nil, err
}
```

**Rust**

**Get the customer 1 of the tenant acme**

```rust
let get_by_id = g.sys.db.get_by_id(GetById::new("crm::acme", "crm", "customers", json!(1)))?;
```

**Java**

**Get the customer 1 of the tenant acme**

```java
var getById = g.sys.db.getById(new GetById("crm::acme", "crm", "customers", 1));
```

**Kotlin**

**Get the customer 1 of the tenant acme**

```kotlin
val getById = g.sys.db.getById(GetById("crm::acme", "crm", "customers", 1))
```

## Without a schema

`g.sys.db.gen.getByIdGen` takes the same arguments and calls the [get by id generated API](https://docs.apimaker.dev/v4/docs/apis-all/schema-apis/auto-generated-schema-based-get-by-id-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.getByIdGen(…)` |
| Python | `g.sys.db.gen.get_by_id_gen(…)` |
| PHP | `$g->sys->db->gen->getByIdGen(…)` |
| C#, Go | `g.Sys.Db.Gen.GetByIdGen(…)` |
| Rust | `g.sys.db.get_by_id_gen(GetById::new(…))` |
| Java, Kotlin | `g.sys.db.gen.getByIdGen(…)` |
