# catalog.set_environment_reference_type (SSISDB Database)

SQL Server 2014

Sets the reference type and environment name associated with an existing environment reference for a project in the Integration Services catalog.

## Syntax

```set_environment_reference_location [ @reference_id = reference_id
, [ @reference_type = ] reference_type
[  , [ @environment_folder_name = ] environment_folder_name ]
```

## Arguments

[ @reference_id = ] reference_id

The unique identifier of the environment reference that is to be updated. The reference_id is bigint.

[ @reference_type = ] reference_type

Indicates whether the environment can be located in the same folder as the project (relative reference) or in a different folder (absolute reference). Use the value R to indicate a relative reference. Use the value A to indicate an absolute reference. The reference_type is char(1).

[ @environment_folder_name = ] environment_folder_name

The folder in which the environment is located. This value is required for absolute references. The environment_folder_name is nvarchar(128).

0 (success)

None

## Permissions

This stored procedure requires one of the following permissions:

• READ and MODIFY permissions on the project, and READ permission on the environment

• Membership to the ssis_admin database role

• Membership to the sysadmin server role

## Errors and Warnings

The following list describes some conditions that may raise an error or warning:

• The folder name, environment name, or reference ID is not valid

• The user does not appropriate permissions

• An absolute reference is specified by using the A character in the reference_location parameter, but the name of the folder was not specified with the environment_folder_name parameter.

## Remarks

A project can have relative or absolute environment references. Relative references refer to the environment by name and require that it resides in the same folder as the project. Absolute references refer to the environment by name and folder, and may refer to environments that reside in a different folder than the project. A project can reference multiple environments.

Important

If a relative reference is specified, the environment_folder_name parameter value is not used, and the environment folder name is automatically set to NULL. If an absolute reference is specified, the environment folder name must be provided in the environment_folder_name parameter.
