How to connect MySQL with SharePoint

This "how-to-connect" documentation will explain the initial configuration of an example connection from MySQL to a SharePoint Online List in Office 365. We will be synchronizing data stored in MySQL.

 

This guide presupposes that you have installed the Layer2 Cloud Connector and that you are familiar with its basic functionality. The Layer2 Cloud Connector User Documentation will provide you with all necessary information.

1. Configuring MySQL

Here the steps for the source... please check text-align:left in the HTML CODE after you saved it.

You are going to need the database name, table name, user name with rights to connect to the database and his password.

2. Configuring the Layer2 Cloud Connector

2.1. Creating a new connection

Create a new connection by using the Create New Connection option in the Actions pane (right-hand side). The new connection will appear at the bottom of the Connection Manager List (left-hand side). Click on your newly created connection to open the connection configuration settings.

 

Choose a meaningful name for your connection and replace the current "New Connection" Connection Title with it.

 

Connections to MySQL can be bi-directional. An initial connection should always be uni-directional to assure that both data entities are identical before switching to bi-directional. Therefore, choose Left to Right as Direction. You can change this setting after your initial synchronisation finished successfully.

2.2. Configuring the Data Entity 1

We will now set up our Data Entities. Go to the data entity “Data Entity 1” to open the configuration settings.

 

Choose a Data Entity Title. It is recommended to give your entities meaningful names to maintain an overview when you decide to set up multiple connections.

 

Select the Data Provider for MySQL from the data provider list. You can search for MySQL by typing into the selection box.

For the Connection String, we need the in step 1 mentioned information. You can copy the below connection string and adjust it to match your gathered information. Use the Verify Connection String option to evaluate if the provided connection string is valid.

 

 

data source=localhost;database=world;user id=mysqluser;

 

 

  • "data source=localhost;" this property points to the server that will be used.
  • "database=name;" this property defines which database will be connected to.
  • "user id=username;" this property sets the user with the rights to connect to the database. 

 

Enter the user account's password into the Password field. The field masks the value for better security.

 

The Select Statement text box is used to define specific data queries. We will be gathering all results from table country. You can copy the below select statement and adjust it to match your needs. Save your changes by using the right-hand pane option Save Changes.

 

SELECT * FROM country

 

Step 2.5 MySQL integration connection string setup.png

 

To check if all necessary columns are received, you can use the Preview Data option on the right-hand pane which will provide you with a pop-up window showing your sample data from your MySQL entity.

2.3. Configuring the Data Entity 2

We are going to send the data to a custom SharePoint Online list. It's required that you set up this list prior to the next steps. Your list should contain matching columns according to your source entity.

 

Use the left-hand pane to switch to the data entity "Data Entity 2". We will be using the Layer2 SharePoint Provider for this setup. 

 

For more information about the SharePoint provider visit:

https://www.layer2solutions.com/support/cloud-connector-faqs/layer2-csom-sharepoint-ado-net-provider.

 

You can copy the below Connection String which contains the minimum of required properties to connect to your custom SharePoint Online list.

 

URL=https://your_custom_sharepoint_list_url/AllItems.aspx;Authentication=Office365;User=User@domain.com;

 

  • "URL=https://your_custom_sharepoint_url/AllItems.aspx;" this property defines the URL of your custom list that will be addressed.
  • "Authentication=Office365;" this property will determine the authentication method used. Office365 is the default authentication method to access Microsoft Office 365 / SharePoint Online. This method will not work in case of federation, e.g. ADFS. For further authentication method you can consult the provider specifications linked above.
  • "User=User@domain.com;" this property should describe the user you wish to connect to SharePoint to. 

 

Enter the password that belongs to the user account used in the connection string into the Password field. Save your changes by using the right-hand pane option Save Changes.

 

Step 3 MySQL integration target setup.png

 

In the next step, we will configure our mapping settings. Click on the Mappings option on the left-hand pane. If your fields from SharePoint are named identical to the fields from your source system, the Enable Auto Mapping option will match those columns. Disabling this option allows you to match your columns as needed. We enabled auto-mapping in our setup. Save your changes by using the right-hand pane option Save Changes.

2.4. Running your connection

To run your connection switch back to the main connection configuration node and use the Run Now Button located on the bottom of the setup page. The Run Synchronization Toolbox will also display the synchronization process. 

 

Step 5 MySQL data integration start.png

 

Below is a data preview of the information we have accessed in our source entity:

This will be the result in our SharePoint Online list after our initial successful synchronization:

If you want to use a bi-directional syncronization, you can now switch your connection directon after our first initial synchronization run finished successfully. See section 3.1 for further information.

3. Hints and known issues

 

3.1. Connection direction

As far as tested, this connection supports uni-directional as well as bi-directional synchronizations. 

 

After adjusting the direction to bi-directional, you should check your Mappings settings again because some systems might include read-only columns that cannot be mapped directly.

 

We also recommend to choose a Conflict Resolution that matches your environments needs. You can find out more about the different conflict resolutions in our Layer2 Cloud Connector User Documentation.

3.2 Bug ADO.NET version 6.10.4

 

There is a known bug in MySQL ADO.NET Connector version 6.10.4 which was actually exposed by a Windows Update on 12nd of April 2018 that includes .NET Framework changes.

 

You will receive the following error message:"The implementation of ADO.NET Provider MySql.Data.MySqlClient.MySqlClientFactory' does not seem adequate for synchronization, since its CreateDataAdapter()-Method returned . Please contact the provider´s manufacturer about this issue or try to use another provider!"

 

To work around the issue please roll-back to a prior version of the MySQL ADO.NET Data Provider until the bug is resolved by MySQL.
