catalog.set_object_parameter_value (SSISDB Database)
Sets the value of a parameter in the Integration Services catalog. Associates the value to an environment variable or assigns a literal value that will be used by default if no other values are assigned.
If no value_type is specified, a literal value for parameter_value is used by default. When a literal value is used, the value_set in the object_parameters view is set to 1. A NULL parameter value is not allowed.
If value_type contains the character R, which denotes a referenced value, parameter_value refers to the name of an environment variable.
The value 20 may be used for object_type to denote a project parameter. In this case, a value for object_name is not necessary, and any value specified for object_name is ignored. This value is used when the user wants to set a project parameter.
The value 30 may be used for object_type to denote a package parameter. In this case, a value for object_name is used to denote the corresponding package. If object_name is not specified, the stored procedure returns an error and terminates.
