# system.detached_parts {#system_tables-detached_parts}
|
|
|
|
Contains information about detached parts of [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) tables. The `reason` column specifies why the part was detached.
|
|
|
|
For user-detached parts, the reason is empty. Such parts can be attached with [ALTER TABLE ATTACH PARTITION\|PART](../../sql-reference/statements/alter/partition.md#alter_attach-partition) command.
|
|
|
|
For the description of other columns, see [system.parts](../../operations/system-tables/parts.md#system_tables-parts).
|
|
|
|
If part name is invalid, values of some columns may be `NULL`. Such parts can be deleted with [ALTER TABLE DROP DETACHED PART](../../sql-reference/statements/alter/partition.md#alter_drop-detached).
