# Get Rows from Result

## ![](/files/9nv6RufdUkAIHwc974jr) Get Rows from Result

### Description <a href="#description" id="description"></a>

The Get Rows from Result transform returns rows that were previously generated by another pipeline in a workflow. You do not need to define any fields in the Get rows from result transform to retrieve all data row fields.

| Hop Engine | <sup>✓</sup> |
| ---------- | ------------ |
| Spark      | X            |
| Flink      | X            |
| Dataflow   | X            |

The rows were passed on to this transform using either the Copy rows to result transform or the Pipeline Executor transform.

You can enter the metadata of the fields you are expecting from the previous pipeline in a workflow.

Tip: The Get Rows From Result is mainly available for historical reasons to build loops through workflows. Check the [Best Practices](/data-shaper-1.21/knowing-the-data-shaper-designer/index-3.md) for better ways of looping in Hop.
