# Microsoft SQL Server Writeback connector

## Intro

Microsoft SQL Server Writeback Connector is a relational database management system developed by Microsoft. Use this connector to export your data from a Domo DataSet to a Microsoft SQL Server database. For more information about the Microsoft SQL Server API, visit their website. ([https://technet.microsoft.com/en-us/library/aa174556(v=sql.80).aspx](https://technet.microsoft.com/en-us/library/aa174556\(v=sql.80\).aspx)).

You export data to a MS SQL database in the Data Center. This topic discusses the fields and menus that are specific to the MS SQL Database Writeback connector user interface. General information for adding DataSets, setting update schedules, and editing DataSet information is discussed in [Adding a DataSet Using a Data Connector](/s/article/360042926274 "Adding a DataSet Using a Data Connector").

<Note>
  **Note:** The owner of a writeback dataset must also be an owner or co-owner of the input dataset.
</Note>

## Prerequisites

<Warning>
  **Important:** If access to your MS SQL database or your MS SQL server is restricted by IP address, you may need to whitelist Domo’s IP addresses before you can successfully connect and a configure a dataset in Domo. Check with your MS SQL database system administrator to determine if this is the case. To get a list of Domo’s IP addresses to whitelist on your MS SQL database or server, see [Whitelisting IP Addresses for Connectors and Federated Adapters](/s/article/360043630093).
</Warning>

To configure this connector, you will need the following:

* A Domo Client ID and Client Secret. To obtain these credentials, do the following:
* Your MS SQL database or schema name.
* The hostname or IP address of your MS SQL database server, such as [db.mycompany.com](http://db.mycompany.com).
* Your MS SQL Database server port number.
* Your MS SQL username and password.
* The port number for your MS SQL server.

You can also include the URL for an MS SQL CA certificate, though this is optional.

## Configuring the Connection

This section enumerates the options in the **Credentials** and **Details** panes in the MS SQL Writeback Connector page. The components of the other panes in this page, **Scheduling** and **Name & Describe Your DataSet**, are universal across most connector types and are discussed in greater length in [Adding a DataSet Using a Data Connector](/s/article/360042926274 "Adding a DataSet Using a Data Connector").

### Credentials Pane

This pane contains fields for entering credentials to connect to your Domo developer account as well as the table in your MS SQL database where you want your data to be copied. The following table describes what is needed for each field:

<table border="1" cellpadding="1" cellspacing="1" data-aura-rendered-by="33:195;a"><thead><tr><th colspan="1" rowspan="1"><p><span class="s1"> Field </span></p></th><th colspan="1" rowspan="1"><p><span class="s1"> Description </span></p></th></tr></thead><tbody><tr><td colspan="1" rowspan="1"><p> Username </p></td><td colspan="1" rowspan="1"><p> Enter your MS SQL username. </p></td></tr><tr><td colspan="1" rowspan="1"><p> Password </p></td><td colspan="1" rowspan="1"><p> Enter your MS SQL password. </p></td></tr><tr><td colspan="1" rowspan="1"><p> Host </p></td><td colspan="1" rowspan="1"><p> Enter your MS SQL database hostname. </p></td></tr><tr><td colspan="1" rowspan="1"><p> Port </p></td><td colspan="1" rowspan="1"><p> Enter your MS SQL database port number. </p></td></tr><tr><td colspan="1" rowspan="1"><p> Database </p></td><td colspan="1" rowspan="1"><p> Enter the name of your MS SQL database. </p></td></tr><tr><td colspan="1" rowspan="1"><p> Certificate </p></td><td colspan="1" rowspan="1"><p> Paste the text for your MS SQL SSL CA certificate. </p></td></tr></tbody></table>

For more information about obtaining these credentials, see "Prerequisites," above.

Once you have entered valid credentials, you can use the same account any time you go to set up a new Domo-MS SQL connection. You can manage connector accounts in the **Accounts** tab in the Data Center. For more information about this tab, see [Managing User Accounts for Connectors](/s/article/360042926054 "Managing User Accounts for Connectors").

### Details Pane

This pane contains a number of fields for specifying your data and indicating where it's going.

<table border="1" cellpadding="1" cellspacing="1" data-aura-rendered-by="33:195;a"><thead><tr><th colspan="1" rowspan="1"><p> Menu </p></th><th colspan="1" rowspan="1"><p> Description </p></th></tr></thead><tbody><tr><td colspan="1" rowspan="1"><p> Input DataSet ID </p></td><td colspan="1" rowspan="1"><p> Enter the DataSet ID (GUID) for the DataSet you want to copy to MS SQL. You can find the ID by opening the details view for the DataSet in the Data Center and looking at the portion of the URL following <span class="mt-font-courier-new"> datasources/ </span>. For example, in the URL <span class="mt-font-courier-new"><span class="nowiki"><a href="https://mycompany.domo.com/datasources/845305d8-da3d-4107-a9d6-13ef3f86d4a4/details/overview" rel="noopener" target="_blank"> [https://mycompany.domo.com/datasources/845305d8-da3d-4107-a9d6-13ef3f86d4a4/details/overview](https://mycompany.domo.com/datasources/845305d8-da3d-4107-a9d6-13ef3f86d4a4/details/overview) </a></span></span>, the DataSet ID is <span class="mt-font-courier-new"> 845305d8-da3d-4107-a9d6-13ef3f86d4a4. </span></p></td></tr><tr><td colspan="1" rowspan="1"><p> Custom Table Name </p></td><td colspan="1" rowspan="1"><p> Enter the name of the table in your MS SQL database where you want your DataSet data to be copied. </p></td></tr><tr><td colspan="1" rowspan="1"><p> SQL Data type for String Values </p></td><td colspan="1" rowspan="1"><p><span> Select an SQL data type for the string values. <br /><b> Note </b>: The default data type is VARCHAR. Please select NVARCHAR if the source data contain Unicode characters. Also, the data type may only work if a new table is created, or an existing table is overwritten with new data. </span></p></td></tr><tr><td colspan="1" rowspan="1"><p> SQL Data type for Integer Values </p></td><td colspan="1" rowspan="1"><p><span> Select an SQL data type for the integer values. <br /><b> Note </b>: The data type may only work if a new table is created, or an existing table is overwritten with new data. </span></p></td></tr><tr><td colspan="1" rowspan="1"><p> String Size </p></td><td colspan="1" rowspan="1"><p><span> Select whether to use the <b> MAX </b> size for STRING types (VARCHAR/NVARCHAR) or provide a <b> Custom </b> size </span></p></td></tr></tbody></table>
