MySQL Connector Setup


The MySQL connector allows you to integrate MySQL into your data flow by pushing or pulling data from MySQL. Follow the steps below to connect CData Arc to MySQL.

Establish a Connection

To allow Arc to use data from MySQL, you must first establish a connection to MySQL. There are two ways to establish this connection:

  • Add a MySQL connector to your flow. Then, in the settings pane, click Create next to the Connection drop-down list.
  • Open the Arc Settings page, then open the Connections tab. Click Add, select MySQL, and click Next.

Note:

  • The login process is only required the first time the connection is created.
  • Connections to MySQL can be re-used across multiple MySQL connectors.

Enter Connection Settings

After opening a new connection dialogue, follow these steps:

  1. Provide the requested information:

    • Name — The static name of the connection. Set this as desired.
    • Type — This is always set to MySQL.
    • Server — The address of the MySQL server you want to connect to.
    • Port — The port to use when connecting to the server.
    • Database — The name of the database you want to target.
    • User — The username to use for logging in.
    • Password — The password for the user entered above.
  2. If needed, click Advanced to open the drop-down menu of advanced connection settings. These should not be needed in most cases.

  3. Click Test Connection to ensure that Arc can connect to MySQL with the provided information. If an error occurs, check all fields and try again.

  4. Click Add Connection to finalize the connection.

  5. In the Connection drop-down list of the connector configuration pane, select the newly-created connection.

  6. Click Save Changes.

Select an Action

After establishing a connection to MySQL, you must choose the action that the MySQL connector will perform. The table below outlines each action and where it belongs in an Arc flow.

Action Description Position in Flow
Upsert Inserts or updates MySQL data. By default, if a record already exists in MySQL, an update is performed on the existing data in MySQL using the values provided from the input. End
Lookup Retrieves a value from MySQL and inserts that value into an already-existing Arc message in the flow.
The Lookup Query determines what value the connector will retrieve from MySQL. It should be formatted as a SQL query against the MySQL tables.
Middle
Select Retrieves data from MySQL and brings it into Arc.
You can use the Filter panel to add filters to the Select. These filters function similarly to WHERE clauses in SQL.
Beginning
Execute Stored Procedures Treats data coming into the connector as input for a stored procedure, and then passes the result down the flow.
You can click the Show Sample Data button to provide sample inputs to the selected Stored Procedure and preview the results.
