+# detached_tables
+
+Contains information of each detached table.
+
+Columns:
+
+- `database` ([String](../../sql-reference/data-types/string.md)) — The name of the database the table is in.
+
+- `name` ([String](../../sql-reference/data-types/string.md)) — Table name.
+
+- `uuid` ([UUID](../../sql-reference/data-types/uuid.md)) — Table uuid (Atomic database).
+
+- `is_permanently` ([UInt8](../../sql-reference/data-types/int-uint.md)) - Flag indicates that the table was detached PERMANENTLY.
+
+- `metadata_path` ([String](../../sql-reference/data-types/string.md)) - Path to the table metadata in the file system.
+
+
+**Example**
+
+```sql
+SELECT * FROM system.detached_tables FORMAT Vertical;
+```

set to "_table_function" when checking access which is not the database
where the actual dict is.

-A trivial stateless slack bot that notifies about new broken tests in ClickHouse CI.
-It checks what happened to our CI during the last check_period hours (1 hour) and
-  notifies us in slack if necessary.
-This script should be executed once each check_period hours (1 hour).
-It will post duplicate messages if you run it more often; it will lose some messages
-  if you run it less often.
-
-You can run it locally with no arguments, it will work in a dry-run mode.
-  Or you can set your own SLACK_URL_DEFAULT.
