## RECOVER

### Name

RECOVER

### Description

This statement is used to restore a previously deleted database, table or partition

grammar:

1. restore database

   ```sql
   RECOVER DATABASE db_name;
   ```

2. restore table

   ```sql
   RECOVER TABLE [db_name.]table_name;
   ```

 3. restore partition

    ```sql
    RECOVER PARTITION partition_name FROM [db_name.]table_name;
    ```

illustrate:

- This operation can only restore meta information that was deleted in the previous period. Default is 1 day. (Configurable through the `catalog_trash_expire_second` parameter in fe.conf)
- If a new meta information with the same name and type is created after the meta information is deleted, the previously deleted meta information cannot be recovered

### Example

1. Restore the database named example_db

```sql
RECOVER DATABASE example_db;
```

2. Restore the table named example_tbl

```sql
RECOVER TABLE example_db.example_tbl;
```

3. Restore the partition named p1 in table example_tbl

```sql
RECOVER PARTITION p1 FROM example_tbl;
```
