# Add SQL worksheets to a Marketplace product

Use [Foundry DevOps](../../devops/overview/index.md) to include your [SQL worksheets](../worksheets/index.md) in [Marketplace products](../../devops/core-concepts/index.md#product) for other users to install and reuse. [Learn how to create your first product.](../../foundry-devops/create-products/index.md)

Packaging a worksheet also lets you package the [Ontology SQL functions](../sql-functions/index.md) published from it, since the function depends on the worksheet.

## Supported features

Worksheets that read from datasets and object types can be included in Marketplace products. When a product is installed, the worksheet is created in the installation project and its SQL is rewritten to reference the resources the installer selects.

* **Datasets:** Each dataset the worksheet references becomes a product input.
* **Object types:** Each object type the worksheet references becomes a product input, along with each of the object type's properties that the worksheet uses.

The following worksheets cannot be included in Marketplace products:

* Worksheets that write to outputs, such as worksheets that create or insert into tables.
* Worksheets that call procedures.
* [Private worksheets](../worksheets/index.md#save-a-worksheet). Save the worksheet into a project before adding it to a product.

## Add SQL worksheets to products

To add a worksheet to a product, first [create a product](../../foundry-devops/create-products/index.md), then [add outputs](../../foundry-devops/create-products/index.md#add-outputs). Choose the **Add files** option to navigate to the worksheet from within the [Compass](../../compass/overview/index.md) filesystem and add it to your product. The datasets and object types the worksheet references are added to the product as inputs.

## Install and upgrade

When installing the product, map each input to a dataset or object type in your environment. Object type property inputs are mapped to properties of the selected object type.

When a new product version is published, upgrading an installation updates the installed worksheet to the new version while keeping your input mappings.
