Sample request​

The example here shows how to make a request with the curl tool:

  • The requested data are subgroup's name (NAME), the connector type (CONNECTOR_TYPE), and extra JDBC flags (EXTRA_JDBC_FLAGS).
  • The request is for the connection subgroups in the Sales Insights catalog.
  • The token is obtained in advance.
  • The query is for the default organization.
  • The address of the AtScale system is: http://example.com:10502/xmla/default

The XML part of the request is as follows:

<?xml version="1.0"?>
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
  <Body>
    <Execute xmlns="urn:schemas-microsoft-com:xml-analysis">
      <Command>
        <Statement>SELECT CONNECTOR_TYPE, EXTRA_JDBC_FLAGS, NAME FROM $system.DBSCHEMA_CONNECTION_SUBGROUPS</Statement>
      </Command>
      <Properties>
        <PropertyList>
          <Catalog>Sales Insights</Catalog>
        </PropertyList>
      </Properties>
    </Execute>
  </Body>
</Envelope>

Here is the full form of the curl request:

curl -X POST \
-H "Authorization:Bearer $token" -H 'Content-Type: application/xml' \
-d '<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">\
<Body><Execute xmlns="urn:schemas-microsoft-com:xml-analysis">\
