catalog.create_environment_variable (SSISDB Database)

Create an environment variable in the Integration Services catalog.

create_environment_variable [ @folder_name = ] folder_name
    , [ @environment_name = ] environment_name
    , [ @variable_name = ] variable_name
    , [ @data_type = ] data_type
    , [ @sensitive = ] sensitive
    , [ @value = ] value
    , [ @description = ] description

[ @folder_name = ] folder_name

The name of the folder that contains the environment. The folder_name is nvarchar(128).

[ @environment_name = ] environment_name

The name of the environment. The environment_name is nvarchar(128).

[ @variable_name = ] variable_name

The name of the environment variable. The variable_name is nvarchar(128).

[ @data_type = ] data_type

The data type of the variable. Supported environment variable data types include Boolean, Byte, DateTime, Double, Int16, Int32, Int64, Single, String, UInt32, and UInt64. Unsupported environment variable data types include Char, DBNull, Object, and Sbyte. The data type of the data_type parameter is nvarchar(128).

[ @sensitive = ] sensitive

Indicates whether the variable contains a sensitive value or not. Use a value of 1 to indicate that the value of the environment variable is sensitive or a value of 0 to indicate that it is not. A sensitive value is encrypted when it is stored. A value that is not sensitive is stored in plaintext.Sensitive is bit.

[ @value = ] value

The value of the environment variable. The value is sql_variant.

[ @description = ] description

The description of the environment variable. The value is nvarchar(1024).

This stored procedure requires one of the following permissions:

  • READ and MODIFY permissions on the environment

  • Membership to the ssis_admin database role

  • Membership to the sysadmin server role

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

  • The folder name, environment name, or environment variable name is not valid

  • The variable name already exists in the environment

  • The user does not have the appropriate permissions

An environment variable can be used to efficiently assign a value to a project parameter or package parameter for use in the execution of a package. Environment variables enable the organization of parameter values. Variable names must be unique within an environment.

The stored procedure validates the data type of the variable to make sure it is supported by the Integration Services catalog.

Tip Tip

Consider using the Int16 data type in Integration Services instead of the unsupported Sbyte data type.

The value passed to this stored procedure with the value parameter will be converted from an Integration Services data type to a SQL Server data type according to the following table:

Integration Services Data Type

SQL Server Data Type

Boolean

bit

Byte

binary, varbinary

DateTime

datetime, datetime2, datetimeoffset, smalldatetime

Double

Exact numeric: decimal, numeric; Approximate numeric: float, real

Int16

smallint

Int32

int

Int64

bigint

Single

Exact numeric: decimal, numeric; Approximate numeric: float, real

String

varchar , nvarchar, char

UInt32

int (This is the closest available mapping to Uint32.)

UInt64

bigint (This is the closest available mapping to Uint64.)
