# DETACH Statement {#detach}
Deletes information about the name table from the server. The server stops knowing about the tables existence.
``` sql
DETACH TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster]
```
This does not delete the tables data or metadata. On the next server launch, the server will read the metadata and find out about the table again.
Similarly, a “detached” table can be re-attached using the `ATTACH` query (with the exception of system tables, which do not have metadata stored for them).
There is no `DETACH DATABASE` query.
