In this section, we provide guides and references to use the MSSQL connector.

Configure and schedule MSSQL metadata and profiler workflows from the OpenMetadata UI:

- [Requirements](#requirements)
- [Metadata Ingestion](#metadata-ingestion)
- [Query Usage](#query-usage)
- [Data Profiler](#data-profiler)
- [Lineage](#lineage)
- [dbt Integration](#dbt-integration)

## Requirements

{%inlineCallout icon="description" bold="OpenMetadata 0.12 or later" href="/deployment"%}
To deploy OpenMetadata, check the Deployment guides.
{%/inlineCallout%}



MSSQL User must grant `SELECT` privilege to fetch the metadata of tables and views.

```sql
-- Create a new user
-- More details https://learn.microsoft.com/en-us/sql/t-sql/statements/create-user-transact-sql?view=sql-server-ver16
CREATE USER Mary WITH PASSWORD = '********';
-- Grant SELECT on table
GRANT SELECT TO Mary;
```
### Python Requirements

To run the MSSQL ingestion, you will need to install:

```bash
pip3 install "openmetadata-ingestion[mssql]"
```

If you want to run the Usage Connector, you'll also need to install:

```bash
pip3 install "openmetadata-ingestion[mssql-usage]"
```

## Metadata Ingestion

All connectors are defined as JSON Schemas.
[Here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/entity/services/connections/database/mssqlConnection.json)
you can find the structure to create a connection to MSSQL.

In order to create and run a Metadata Ingestion workflow, we will follow
the steps to create a YAML configuration able to connect to the source,
process the Entities if needed, and reach the OpenMetadata server.

The workflow is modeled around the following
[JSON Schema](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/workflow.json)

### 1. Define the YAML Config

This is a sample config for MSSQL:


{% codePreview %}

{% codeInfoContainer %}

#### Source Configuration - Service Connection

{% codeInfo srNumber=1 %}

**scheme**: Defines how to connect to MSSQL. We support `mssql+pytds`, `mssql+pyodbc`, and `mssql+pymssql`.

{% /codeInfo %}

{% codeInfo srNumber=2 %}

**username**: Specify the User to connect to MSSQL. It should have enough privileges to read all the metadata.

{% /codeInfo %}

{% codeInfo srNumber=3 %}

**password**: Password to connect to MSSQL.

{% /codeInfo %}

{% codeInfo srNumber=4 %}

**hostPort**: Enter the fully qualified hostname and port number for your MSSQL deployment in the Host and Port field.

{% /codeInfo %}

{% codeInfo srNumber=5 %}

**Database**: The database of the data source is an optional parameter, if you would like to restrict the metadata reading to a single database. If left blank, OpenMetadata ingestion attempts to scan all the databases.

{% /codeInfo %}

{% codeInfo srNumber=6 %}

**uriString**: In case of a `pyodbc` connection.

{% /codeInfo %}

{% partial file="/v1.3/connectors/yaml/ingestion-sink-def.md" /%}

{% partial file="/v1.3/connectors/yaml/workflow-config-def.md" /%}

#### Advanced Configuration

{% codeInfo srNumber=7 %}

**Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

{% /codeInfo %}

{% codeInfo srNumber=8 %}

**Connection Arguments (Optional)**: Enter the details for any additional connection arguments such as security or protocol configs that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

- In case you are using Single-Sign-On (SSO) for authentication, add the `authenticator` details in the Connection Arguments as a Key-Value pair as follows: `"authenticator" : "sso_login_url"`
