  • General keys typically found in assoc are:
  • "ConnectionName" "AzureTables"
    "Location" query given as a string
    "Redownload" whether to redownload cache files
  • Keys required in assoc for Azure tables connections are:
  • "Account" Azure storage account name
    "Container" container the table is located in
  • Possible forms of "Location" when connecting to Azure tables include:
  • "query" Azure ODATA filter specification
  • Use Import to retrieve data from the linked resource.
  • Account Setting & Authentication

  • Possible values for Authentication are:
  • Automatic attempt to use saved credentials or give a dialog
    "Dialog" give authentication parameters via a dialog
    SystemCredential ["key"] retrieve authentication information from secure storage

    Basic Examples  (2)

    Create a DataConnectionObject to data located in an Azure table:

    Wolfram Language code: DataConnectionObject[ <|"ConnectionName" -> "AzureTables", "Account" -> "wolframdataconnection", "Container" -> "samples", "Location" -> "PartitionKey eq 'a'" |>]

    Retrieve data from an Azure table using Import :

    Wolfram Language code: Import@DataConnectionObject[ <|"ConnectionName" -> "AzureTables", "Account" -> "wolframdataconnection", "Container" -> "samples", "Location" -> "PartitionKey eq 'a'" |>]

    Authentication  (1)

    Give credentials to AzureTables:

    Wolfram Language code: Import@DataConnectionObject[ <|"ConnectionName" -> "AzureTables", "Account" -> "wolframdataconnection", "Container" -> "samples", "Location" -> "PartitionKey eq 'a'"|>, Authentication -> <|"SASToken" -> "token"|>]
