Create an environment variable in the Integration Services catalog.

Syntax

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

Arguments

[ @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).

Return Code Value

0 (success)

Result Sets

None

Permissions

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

Errors and Warnings

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

Remarks

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

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.)
