# UNDROP TABLE

Cancels the dropping of the table.

Beginning with ClickHouse version 23.3 it is possible to UNDROP a table 
within 8 minutes of issuing the DROP TABLE statement.  Dropped tables are listed in 
a system table called `system.dropped_tables`.

:::note
UNDROP TABLE is experimental.  To use it add this setting: 
```sql
set allow_experimental_undrop_table_query = 1;
```
:::

:::tip
Also see [DROP TABLE](/docs/en/sql-reference/statements/drop.md)
:::

Syntax:

``` sql
UNDROP [TEMPORARY] TABLE [IF EXISTS] [db.]name [ON CLUSTER cluster] [SYNC]
```

**Example**

``` sql
set allow_experimental_undrop_table_query = 1;
```

```sql
CREATE TABLE undropMe
(
    `id` UInt8
)
ENGINE = MergeTree
ORDER BY id
```

```sql
DROP TABLE undropMe
```
```sql
SELECT *
FROM system.dropped_tables
FORMAT Vertical
```
```response
