WHERE OBJECT_TYPE = 'ACTIVE_RELATIONSHIP'įor schema rowsets that have restrictions, the query must include the SYSTEMRESTRICTSCHEMA function. The following example for DISCOVER_CALC_DEPENDENCY illustrates the use of the WHERE clause for supplying a parameter to the query: SELECT * FROM $System.DISCOVER_CALC_DEPENDENCY

Although DMV query syntax is based on a SQL SELECT statement, it does not support the full syntax of a SELECT statement. The DMV query syntax is based on the SELECT (DMX) statement. The query engine for DMVs is the Data Mining parser. To learn more about real-time monitoring using traces, see Use SQL Server Profiler to Monitor Analysis Services. To monitor operations in real-time, use tracing instead. Most DMV queries use a SELECT statement and the $System schema with an XML/A schema rowset, for example: SELECT * FROM $System.ĭMV queries return information about server and object state at the time the query is run. In addition, the result is returned in a table format that is easier to read and copy. For most administrators, writing a DMV query is simpler because the syntax is based on SQL. Some DMVs are not supported because they require Analysis Services server admin permissions.ĭMV queries are an alternative to running XML/A Discover commands. Schema rowsets are predescribed tables that contain information about Analysis Services objects and server state, including database schema, active sessions, connections, commands, and jobs that are executing on the server.įor Power BI Premium datasets, DMVs for querying through the XMLA endpoint are limited to those that require database admin permissions. The query, based on SQL, is an interface to schema rowsets. Analysis Services Dynamic Management Views (DMVs) are queries that return information about model objects, server operations, and server health.
