|

DETACH TABLE|VIEW [IF EXISTS] [db.]name [PERMANENTLY] [ON CLUSTER cluster]
|
||||
```
|

|
||||
This does not delete the table’s data or metadata. On the next server launch, the server will read the metadata and find out about the table again.
|
||||
Detaching does not delete the data or metadata for the table or view. If the table or view was not detached `PERMANENTLY`, on the next server launch the server will read the metadata and recall the table/view again. If the table or view was detached `PERMANENTLY`, there will be no automatic recall.
|
||||
|
||||
Whether the table was detached permanently or not, in both cases you can reattach it using the [ATTACH](../../sql-reference/statements/attach.md) query (with the exception of system tables, which do not have metadata stored for them).
|
||||
|
||||
`ATTACH MATERIALIZED VIEW` doesn't work with short syntax (without `SELECT`), but you can attach it using the `ATTACH TABLE` query.
|
||||
|
||||
Note that you can not detach permanently the table which is already detached (temporary). But you can attach it back and then detach permanently again.
|
||||
|
||||
Also you can not [DROP](../../sql-reference/statements/drop.md#drop-table) the detached table, or [CREATE TABLE](../../sql-reference/statements/create/table.md) with the same name as detached permanently, or replace it with the other table with [RENAME TABLE](../../sql-reference/statements/rename.md) query.
|
||||
|
||||
Similarly, a “detached” table can be re-attached using the [ATTACH](../../sql-reference/statements/attach.md) query (with the exception of system tables, which do not have metadata stored for them).
