MSSQL setup requirements
To set up MSSQL in Stitch, you need:
Privileges in MSSQL that allow you to create/manage users. This is required to create the Stitch database user.
A server that:
- Uses case-insensitive collation. Refer to Microsoft’s documentation for more info.
- Allows connections over TCP/IP
- Allows mixed mode authentication
Make sure your server is set up properly before continuing. If you need some help figuring out your hosting details, we recommend looping in a member of your engineering team.
Step 1: Configure database connection settings
In this step, you’ll configure the database server to allow traffic from Stitch to access it. There are two ways to connect your database:
- A direct connection will work if your database is publicly accessible.
- An SSH tunnel is required if your database isn’t publicly accessible. This method uses a publicly accessible instance, or an SSH server, to act as an intermediary between Stitch and your database. The SSH server will forward traffic from Stitch through an encrypted tunnel to the private database.
Click the option you’re using below and follow the instructions.
For the connection to be successful, you’ll need to configure your firewall to allow access from our IP addresses. Whitelist the following IPs before continuing onto the next step:
- Follow the steps in the Setting up an SSH Tunnel for a database connection guide to set up an SSH tunnel for MSSQL.
- Complete the steps in this guide after the SSH setup is complete.
Step 2: Create a Stitch database user
Next, you’ll create a dedicated database user for Stitch. This will ensure Stitch is visible in any logs or audits, and allow you to maintain your privilege hierarchy.
Creating a user with
SELECT privileges can either be done via a query or the MSSQL UI. In this section, we’ll walk you through using the query method.
us_english. Issues with replication may arise if a different setting is used.
- Log into your database.
Create a SQL login for the Stitch database user:
CREATE LOGIN <stitch_username> WITH PASSWORD=’<password>’ go
Grant the Stitch user access to the database:
USE <database_name> go
Create the Stitch database user and map them to the database:
CREATE USER <stitch_username> FOR LOGIN go
Grant the Stitch user
SELECTprivileges. To grant
SELECTprivileges to all tables in the database, run this command:
GRANT SELECT to <stitch_username> go
If you want to limit the Stitch user to specific tables, run this command instead:
GRANT SELECT ON <schema_name>.<table_name> TO <stitch_username> go
See the Privileges list tab for an explanation of why these permissions are required by Stitch.
In the table below are the database user privileges Stitch requires to connect to and replicate data from a MSSQL database.

Required to select rows from tables in a database.
Step 3: Connect Stitch
In this step, you’ll complete the setup by entering the database’s connection details and defining replication settings in Stitch.
Step 3.1: Define the database connection details
- If you aren’t signed into your Stitch account, sign in now.
On the Stitch Dashboard page, click the Add Integration button.
- Locate and click the MSSQL icon.
Fill in the fields as follows:
Integration Name: Enter a name for the integration. This is the name that will display on the Stitch Dashboard for the integration; it’ll also be used to create the schema in your destination.
For example, the name “Stitch MSSQL” would create a schema called
stitch_mssqlin the destination. Note: The schema name cannot be changed after the integration is saved.
Host (Endpoint): Enter the host address (endpoint) used by the MSSQL instance. For example: This could be a network address such as
188.8.131.52, or a server endpoint like
Port: Enter the port used by the instance. The default is
Username: Enter the Stitch MSSQL database user’s username.
Password: Enter the password for the Stitch MSSQL database user.
Database: Optional: Enter the name of the default database Stitch will connect to. Stitch will ‘find’ all databases you give the Stitch user access to - a default database is only used to test and complete the connection.
Step 3.2: Define the SSH connection details
If you’re using an SSH tunnel to connect your MSSQL database to Stitch, you’ll also need to define the SSH settings. Refer to the Setting up an SSH Tunnel for a database connection guide for assistance with completing these fields.
- Click the Encryption Type menu.
Select SSH to display the SSH fields.
Fill in the fields as follows:
Remote Address: Enter the public IP address or hostname of the server Stitch will SSH into.
SSH Port: Enter the SSH port on your server. (
SSH User: Enter the Stitch Linux (SSH) user’s username.
Step 3.3: Define the SSL connection details
Click the Connect using SSL checkbox if you’re using an SSL connection. Note: The database must support and allow SSL connections for this setting to work correctly.
Step 3.4: Create a replication schedule
In the Replication Frequency section, you’ll create the integration’s replication schedule. An integration’s replication schedule determines how often Stitch runs a replication job, and the time that job begins.
Stitch offers two methods of creating a replication schedule:
- Replication Frequency: This method requires selecting the interval you want replication to run for the integration. Start times of replication jobs are based on the start time and duration of the previous job. Refer to the Replication Frequency documentation for more information and examples.
Anchor scheduling: Based on the Replication Frequency, or interval, you select, this method “anchors” the start times of this integration’s replication jobs to a time you select to create a predictable schedule. Anchor scheduling is a combination of the Anchor Time and Replication Frequency settings, which must both be defined to use this method. Additionally, note that:
- A Replication Frequency of at least one hour is required to use anchor scheduling.
An initial replication job may not begin immediately after saving the integration, depending on the selected Replication Frequency and Anchor Time. Refer to the Anchor Scheduling documentation for more information.
- You’ll need to contact support to request using an Anchor Time with this integration.
To keep your row usage low, consider setting the integration to replicate less frequently. See the Understanding and Reducing Your Row Usage guide for tips on reducing your usage.
Step 3.5: Save the integration
When finished, click Save Integration.
Stitch will perform a connection test to the MSSQL database; if successful, a Success! mesage will display at the top of the screen. Note: This test may take a few minutes to complete.
Step 4: Select data to replicate
The last step is to select select the tables and columns you want to replicate.
You can select tables and columns by:
- In the Integration Details page, click the Tables to Replicate tab.
- Locate a table you want to replicate.
- Click the checkbox next to the object’s name. A green checkmark means the object is set to replicate.
- If there are child objects, they’ll automatically display and you’ll be prompted to select some.
After you set a table to replicate, the Settings page will display. Note: When you track a table, by default all columns will also be tracked.
In the Settings page, define the table’s Replication Method and, if using Key-based Incremental Replication, its Replication Key.
- Repeat this process for every table you want to replicate.
Initial and historical replication jobs
After you finish setting up MSSQL, its Sync Status may show as Pending on either the Stitch Dashboard or in the Integration Details page.
For a new integration, a Pending status indicates that Stitch is in the process of scheduling the initial replication job for the integration. This may take some time to complete.
Initial replication jobs with Anchor Scheduling
If using Anchor Scheduling, an initial replication job may not kick off immediately. This depends on the selected Replication Frequency and Anchor Time. Refer to the Anchor Scheduling documentation for more information.
Free historical data loads
The first seven days of replication, beginning when data is first replicated, are free. Rows replicated from the new integration during this time won’t count towards your quota. Stitch offers this as a way of testing new integrations, measuring usage, and ensuring historical data volumes don’t quickly consume your quota.
Connection issues and collation
If you’re experiencing connection issues and have verified that the database user has the correct permissions, check your server’s collation setting.
Connecting MSSQL to Stitch successfully requires that your server use case-insensitive collation.
Data discrepancies and database user language settings
If you’re missing data, check that the database user’s language setting is set to
us_english. Using a different setting can cause problems with replication, including issues with properly identifying new and updated data.
