Introduction
In SSIS, parameters and variables control dynamic behavior and allow packages to adapt to different environments.
This article gives you a quick overview of how they differ and when to use each with ZappySys SSIS PowerPack components.
Comparison
Parameters
Used to pass external values (API URLs, credentials, file paths).
They are read-only during execution and best for environment configuration.
Variables
Used to store values that can change while the package runs (flags, pagination, results).
They are read/write and ideal for runtime logic.
Summary
- Parameters = fixed input from outside.
- Variables = dynamic values modified at runtime.
- Combine both for flexible, maintainable packages.
