# Transformation
Transformation jobs copy your source data to your target and are written using familiar SQL code. These Quickstart guides will provide you with the essential skills to write a transformation job, however, Upsolver includes an extensive list of functions and operators that you can use to build advanced solutions for your requirements.

## 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://upsolver.gitbook.io/content/quickstarts-1/jobs/transformation.md?ask=&goal=
```
`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.
