# Generate rows

The Generate rows step outputs a specified number of rows. By default, the rows are empty; however, they can contain a number of static fields. You can use this step to generate a fixed number of rows for testing purposes, for example, if you want to produce exactly 12 rows for 12 months. You can also use the step to generate one row as an initiating point for your transformation. For example, you could generate one row that contains two or three field values that can be used to parametrize your SQL and then generate usable rows.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/generate-rows.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
