# DROP PROPERTY GRAPH — remove an SQL-property graph

## Synopsis

```
DROP PROPERTY GRAPH [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
```

<a id="id-1.9.3.127.5"></a>

## Description

`DROP PROPERTY GRAPH` drops an existing property graph. To execute this command you must be the owner of the property graph. 

<a id="id-1.9.3.127.6"></a>

## Parameters

**`IF EXISTS`**

 Do not throw an error if the property graph does not exist. A notice is issued in this case. **`name`**

 The name (optionally schema-qualified) of the property graph to remove. **`CASCADE`**

 Automatically drop objects that depend on the property graph, and in turn all objects that depend on those objects (see [Section 5.17](ddl-depend.md)). **`RESTRICT`**

 Refuse to drop the property graph if any objects depend on it. This is the default. <a id="id-1.9.3.127.7"></a>

## Examples


DROP PROPERTY GRAPH g1;


<a id="id-1.9.3.127.8"></a>

## Compatibility

`DROP PROPERTY GRAPH` conforms to ISO/IEC 9075-16 (SQL/PGQ), except that the standard only allows one property graph to be dropped per command, and apart from the `IF EXISTS` option, which is a PostgreSQL extension.
