You can use namespace and data queries with most connectors. You use namespace queries to provide a list of names and realize a connector's functionality and the data values available from a specific server. You use data queries to return data from the connector.

Features

You can combine a namespace query with advanced HTML and JavaScript to create an interactive form with the results of the query. A mode that ends in "List" is a namespace query and returns a list box. Namespace queries are used in the SAP MII templates and with the ad-hoc data browsing dialogs in the SAP MII applets. Examples of namespace query modes include the following:

  • ServerList

  • GroupList

  • TagList

  • TableList

  • ColumnList

  • ModeList

  • TimePeriodList

  • KPIList

Some connectors provide a legend describing the data items returned by the data query. Examples of data query modes include the following:

  • History

  • HistoryEvent

  • Current

  • Statistics

  • Query

  • FixedQuery

  • Command

  • AlarmHistory

  • AlarmSummary

  • AlarmStatistics
