+## SHOW SETTINGS {#show-settings}
+
+Returns a list of system settings and their values. Selects data from the [system.settings](../../operations/system-tables/settings.md) table.
+
+**Syntax**
+
+```sql
+SHOW [CHANGED] SETTINGS LIKE|ILIKE <name>;
+```
+
+**Clauses**
+
+`LIKE` clause needs a setting name or part of the name without globs.
+
+`ILIKE` clause can contain globs such as `%` or `_`.
+
+When the `CHANGED` clause is used, the query returns only settings changed from their default values.
+
+**Examples**
+
+Query with the `LIKE` clause:
+
+```sql
+SHOW SETTINGS LIKE 'send_timeout';
+```
+Result:
+
+```text
+┌─name─────────┬─type────┬─value─┐
+│ send_timeout │ Seconds │ 300   │
+└──────────────┴─────────┴───────┘
+```
+
+Query with the `ILIKE` clause:
+
+```sql
+SHOW SETTINGS ILIKE '%CONNECT_timeout%'
+```
+
+Result:
+
+```text
+┌─name────────────────────────────────────┬─type─────────┬─value─┐
+│ connect_timeout                         │ Seconds      │ 10    │
+│ connect_timeout_with_failover_ms        │ Milliseconds │ 50    │
+│ connect_timeout_with_failover_secure_ms │ Milliseconds │ 100   │
+└─────────────────────────────────────────┴──────────────┴───────┘
+```
+
+Query with the `CHANGED` clause:
+
+```sql
+SHOW CHANGED SETTINGS ILIKE '%MEMORY%'
+```
+
+Result:
+
+```text
+┌─name─────────────┬─type───┬─value───────┐
+│ max_memory_usage │ UInt64 │ 10000000000 │
+└──────────────────┴────────┴─────────────┘

+## SHOW SETTINGS {#show-settings}
+
+Возвращает список системных настроек и их значений. Использует данные из таблицы [system.settings](../../operations/system-tables/settings.md).
+
+**Синтаксис**
+
+```sql
+SHOW [CHANGED] SETTINGS LIKE|ILIKE <name>;
+```
+
+**Секции**
+
+При использовании `LIKE` необходимо указывать имя или часть имени системной настройки без символов подстановки.
+
+При использовании `ILIKE` имя системной настройки может содержать символы подстановки, такие как `%` или `_`.
+
+Если используется `CHANGED`, запрос вернет только те настройки, значения которых были изменены, т.е. отличны от значений по умолчанию.
+
+**Примеры**
+
+Запрос с использованием `LIKE`:
+
+```sql
+SHOW SETTINGS LIKE 'send_timeout';
+```
+Результат:
+
+```text
+┌─name─────────┬─type────┬─value─┐
+│ send_timeout │ Seconds │ 300   │
+└──────────────┴─────────┴───────┘
+```
+
+Запрос с использованием `ILIKE`:
+
+```sql
+SHOW SETTINGS ILIKE '%CONNECT_timeout%'
+```
+
+Результат:
+
+```text
+┌─name────────────────────────────────────┬─type─────────┬─value─┐
+│ connect_timeout                         │ Seconds      │ 10    │

+│ connect_timeout_with_failover_secure_ms │ Milliseconds │ 100   │
+└─────────────────────────────────────────┴──────────────┴───────┘
+```
+
+Запрос с использованием `CHANGED`:
+
+```sql
