This article outlines how to use the Copy Activity in Azure Data Factory and Synapse Analytics pipelines to copy data from a Microsoft Access data store. It builds on the copy activity overview article that presents a general overview of copy activity.

Supported capabilities

This Microsoft Access connector is supported for the following capabilities:

Supported capabilities IR
Copy activity (source/sink) ②
Lookup activity ②

① Azure integration runtime ② Self-hosted integration runtime

For a list of data stores that are supported as sources/sinks by the copy activity, see the Supported data stores table.

Prerequisites

To use this Microsoft Access connector, you need to:

  • Set up a Self-hosted Integration Runtime. See Self-hosted Integration Runtime article for details.
  • Install the Microsoft Access ODBC driver for the data store on the Integration Runtime machine.

Note

This connector works with Microsoft Access 2016 version of ODBC driver. The recommended driver version is 16.00.5378.1000 or above.

Getting started

To perform the Copy activity with a pipeline, you can use one of the following tools or SDKs:

Create a linked service to Microsoft Access using UI

Use the following steps to create a linked service to Microsoft Access in the Azure portal UI.

  1. Browse to the Manage tab in your Azure Data Factory or Synapse workspace and select Linked Services, then click New:

  2. Search for Access and select the Microsoft Access connector.

    Select the Microsoft Access connector.

  3. Configure the service details, test the connection, and create the new linked service.

    Configure a linked service to Microsoft Access.

Connector configuration details

The following sections provide details about properties that are used to define Data Factory entities specific to Microsoft Access connector.

Linked service properties

The following properties are supported for Microsoft Access linked service:

Property Description Required
type The type property must be set to: MicrosoftAccess Yes
connectionString The ODBC connection string excluding the credential portion. You can specify the connection string or use the system DSN (Data Source Name) you set up on the Integration Runtime machine (you need still specify the credential portion in linked service accordingly).
You can also put a password in Azure Key Vault and pull the password configuration out of the connection string. Refer to Store credentials in Azure Key Vault with more details.		 Yes
authenticationType Type of authentication used to connect to the Microsoft Access data store.
Allowed values are: Basic and Anonymous.		 Yes
userName Specify user name if you are using Basic authentication. No
password Specify password for the user account you specified for the userName. Mark this field as a SecureString to store it securely, or reference a secret stored in Azure Key Vault. No
credential The access credential portion of the connection string specified in driver-specific property-value format. Mark this field as a SecureString. No
connectVia The Integration Runtime to be used to connect to the data store. A Self-hosted Integration Runtime is required as mentioned in Prerequisites. Yes

Example:

{
    "name": "MicrosoftAccessLinkedService",
    "properties": {
        "type": "MicrosoftAccess",
        "typeProperties": {
            "connectionString": "Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=<path to your DB file e.g. C:\\mydatabase.accdb>;",

                "value": "<password>"
            }
        },
        "connectVia": {
            "referenceName": "<name of Integration Runtime>",
            "type": "IntegrationRuntimeReference"
        }
    }
}

Dataset properties

For a full list of sections and properties available for defining datasets, see the datasets article. This section provides a list of properties supported by Microsoft Access dataset.

To copy data from Microsoft Access, the following properties are supported:

Property Description Required
type The type property of the dataset must be set to: MicrosoftAccessTable Yes
tableName Name of the table in the Microsoft Access. No for source (if "query" in activity source is specified);
Yes for sink

Example

{
    "name": "MicrosoftAccessDataset",
    "properties": {

}

Copy activity properties

For a full list of sections and properties available for defining activities, see the Pipelines article. This section provides a list of properties supported by Microsoft Access source.

Microsoft Access as source
