# EXPORT SCHEMA command

The EXPORT SCHEMA command returns the resource objects and the statements used to create those resource objects across all schemas within the current service group.

The EXPORT SCHEMA  command returns the resource objects in a specific schema and the statements used to create these resource objects.

The following table describes the returned information of these commands:

 | Column | Description
 | `entity` | The resource object that constitutes the schema, which can be a graph, graph type or index.
 | `statement` | The statement that defines the resource object.

## Prerequisites

To run `EXPORT SCHEMA`, you must be the user with the role `ADMIN`. For more information, see [Roles and privileges](https://dev-docs.nebula-graph.io/v5.3.2/server-admin/authorization/).

## Syntax

 export_schemas_command export_schema_command  

````
export_schemas_command ::=
    'EXPORT' 'SCHEMA'
export_schema_command ::=
    'EXPORT' 'SCHEMA' schema_reference

## Parameters

### `schema_reference`

The reference to the path of the schema. It specifies the path of the schema to be exported.

The path is case-sensitive and must match the path of an existing schema. Both absolute and relative schema paths can be used in the command.

## Examples
