Information about [Refreshable Materialized Views](../../sql-reference/statements/create/view.md#refreshable-materialized-view). Contains all refreshable materialized views, regardless of whether there's a refresh in progress or not.
Columns:
-`database` ([String](../../sql-reference/data-types/string.md)) — The name of the database the table is in.
-`last_refresh_time` ([DateTime](../../sql-reference/data-types/datetime.md)) — Time of the last refresh attempt. `NULL` if no refresh attempts happened since server startup or table creation.
-`last_success_time` ([DateTime](../../sql-reference/data-types/datetime.md)) — Time of the last successful refresh. `NULL` if no successful refreshes happened since server startup or table creation.
-`duration_ms` ([UInt64](../../sql-reference/data-types/int-uint.md)) — How long the last refresh attempt took.
-`next_refresh_time` ([DateTime](../../sql-reference/data-types/datetime.md)) — Time at which the next refresh is scheduled to start.
-`remaining_dependencies` ([Array(String)](../../sql-reference/data-types/array.md)) — If the view has [refresh dependencies](../../sql-reference/statements/create/view.md#refresh-dependencies), this array contains the subset of those dependencies that are not satisfied for the current refresh yet. If `status = 'WaitingForDependencies'`, a refresh is ready to start as soon as these dependencies are fulfilled.
-`exception` ([String](../../sql-reference/data-types/string.md)) — if `last_refresh_result = 'Exception'`, i.e. the last refresh attempt failed, this column contains the corresponding error message and stack trace.
