Define parameter value

The Define Parameter Value task allows you to manually assign a new value to an existing parameter within your data flow in Gaio DataOS. It’s a key feature for controlling flow execution, dynamically updating context, or overriding default values at runtime.

How to Use

1. Open the Task

Navigate to: Tasks > ETL > Define Parameter Value

---

2. Configure the Task Fields

• Label: (Optional) A custom label to identify this task in your flow.

• Param: Select the parameter you want to update. It must already exist in the environment.

• Default: The parameter’s original default value (read-only).

• Current: The current value in use before the update (read-only).

• Value: The new value that will be assigned to the parameter during flow execution.

The value defined here will temporarily override the current parameter value during the flow run, and can be reused by other tasks in the sequence.

---

3. Save and Apply

• After entering the new value in the Value field, click Save.

• When the flow is executed, the parameter will be updated in real time with the new assigned value.

Use Cases

• Dynamically update filters or variables before executing queries

• Apply conditional logic based on runtime-defined values

• Customize executions using user input or contextual values

• Override previously inherited parameters from other flows or default settings
