# Ayarlardaki kısıtlamalar {#constraints-on-settings}
Ayarlardaki kısıtlamalar, `profiles` bu bölüm `user.xml` yapılandırma dosyası ve kullanıcıların bazı ayarları değiştirmelerini yasakla `SET` sorgu.
Kısıtlamalar aşağıdaki gibi tanımlanır:
``` xml
<profiles>
<user_name>
<constraints>
<setting_name_1>
<min>lower_boundary</min>
</setting_name_1>
<setting_name_2>
<max>upper_boundary</max>
</setting_name_2>
<setting_name_3>
<min>lower_boundary</min>
<max>upper_boundary</max>
</setting_name_3>
<setting_name_4>
<readonly/>
</setting_name_4>
</constraints>
</user_name>
</profiles>
```
Kullanıcı kısıtlamaları ihlal etmeye çalışırsa, bir istisna atılır ve ayar değiştirilmez.
Desteklenen üç tür kısıtlama vardır: `min`, `max`, `readonly`. Bu `min` ve `max` kısıtlamalar, sayısal bir ayar için üst ve alt sınırları belirtir ve birlikte kullanılabilir. Bu `readonly` kısıtlama, kullanıcının karşılık gelen ayarı hiç değiştiremeyeceğini belirtir.
**Örnek:** İzin vermek `users.xml` hatları içerir:
``` xml
<profiles>
<default>
<max_memory_usage>10000000000</max_memory_usage>
<force_index_by_date>0</force_index_by_date>
...
<constraints>
<max_memory_usage>
<min>5000000000</min>
<max>20000000000</max>
</max_memory_usage>
<force_index_by_date>
<readonly/>
</force_index_by_date>
</constraints>
</default>
</profiles>
```
Aşağıdaki sorgular tüm atma istisnaları:
``` sql
SET max_memory_usage=20000000001;
SET max_memory_usage=4999999999;
SET force_index_by_date=1;
```
``` text
Code: 452, e.displayText() = DB::Exception: Setting max_memory_usage should not be greater than 20000000000.
Code: 452, e.displayText() = DB::Exception: Setting max_memory_usage should not be less than 5000000000.
Code: 452, e.displayText() = DB::Exception: Setting force_index_by_date should not be changed.
```
**Not:** bu `default` profil özel işleme sahiptir: tüm kısıtlamalar için tanımlanan `default` profil varsayılan kısıtlamalar haline gelir, bu nedenle bu kullanıcılar için açıkça geçersiz kılınana kadar tüm kullanıcıları kısıtlarlar.
