# Writeback transformed data from InfoBridge

Infobridge in plan not only transforms and integrates data from multiple sources but also enables direct writeback to a Microsoft Fabric SQL database. This process allows the transformed dataset produced in a bridge to become a governed dataset stored in the enterprise data platform.

This section explains how to write back the output of a bridge to a Fabric SQL database destination.

### Writeback overview

In the following example, a sample bridge is created using **Infobridge** that merges two data sources:

* **Query 1**: A planning sheet containing actual revenue from 2026
* **Query 2**: An external Excel file containing forecast and projected revenue

Through the **Merge Query** operation, measures from both queries are combined to produce a unified dataset that integrates actual and forecasted values.

Once the transformation is complete, the merged dataset can be written back to a **Fabric SQL database**. This writeback allows the combined data to be used by downstream applications such as analytics, planning models, and operational reporting systems.

Here's an example of transformed data:

### Add new destination

1. Select **Add new destination** to add a writeback destination.
2. Enter the Fabric SQL connection information, including the connection name, database name for writeback, schema, writeback table name, decimal precision, and text length.<br>

3. The writeback destination is configured.<br>

### Write back data

1. Select **Writeback** from the **Writeback** tab. This instruction writes back the merged query to the chosen destination.<br>

## 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.fabricplan.com/planning-sheets/how-tos/infobridge/writeback-transformed-data-from-infobridge.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.
