# Count

> Get the total number of records in a collection or matching a specific query using API Maker's g.sys.db.count method.

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

**Count the customers of the tenant acme**

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

**Python**

**Count the customers of the tenant acme**

```python
count = await g.sys.db.count(
    'crm::acme', 'crm', 'customers',
    find={
        'first_name': 'Bob',
    },
)
```

**PHP**

**Count the customers of the tenant acme**

```php
$count = $g->sys->db->count(
    'crm::acme', 'crm', 'customers',
    find: [
        'first_name' => 'Bob',
    ],
);
```

**C#**

**Count the customers of the tenant acme**

```csharp
var count = await g.Sys.Db.Count(new Count("crm::acme", "crm", "customers")
{
    Find = new JsonObject
    {
        ["first_name"] = "Bob",
    },
});
```

**Go**

**Count the customers of the tenant acme**

```go
count, err := g.Sys.Db.Count(am.Count{
	Instance: "crm::acme", Database: "crm", Collection: "customers",
	Find: am.M{
		"first_name": "Bob",
	},
})
if err != nil {
	return nil, err
}
```

**Rust**

**Count the customers of the tenant acme**

```rust
let count = g.sys.db.count(
    Count::new("crm::acme", "crm", "customers")
        .find(json!({
            "first_name": "Bob",
        })),
)?;
```

**Java**

**Count the customers of the tenant acme**

```java
var count = g.sys.db.count(new Count("crm::acme", "crm", "customers")
    .find(Map.of(
        "first_name", "Bob"
    )));
```

**Kotlin**

**Count the customers of the tenant acme**

```kotlin
val count = g.sys.db.count(
    Count("crm::acme", "crm", "customers")
        .find(mapOf(
            "first_name" to "Bob",
        )),
)
```

## Without a schema

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