—   AX_LONG_RUNNING_QUERY_TRACE

— ————————————————————–
— Find long running queries from Dynamics AX with source code
— requires client tracing being enabled on the AOS configuration
—————————————————————-

SELECT TOP 100 [CREATED_DATETIME],[DATABASE_NAME],[ROW_NUM], [AX_USER_ID], [SQL_DURATION], [SQL_TEXT], [CALL_STACK], [TRACE_CATEGORY], [TRACE_EVENT_CODE], [TRACE_EVENT_DESC], [TRACE_EVENT_DETAILS], [CONNECTION_TYPE], [SQL_SESSION_ID], [AX_CONNECTION_ID], [IS_LOBS_INCLUDED], [IS_MORE_DATA_PENDING], [ROWS_AFFECTED], [ROW_SIZE], [ROWS_PER_FETCH], [IS_SELECTED_FOR_UPDATE], [IS_STARTED_WITHIN_TRANSACTION], [SQL_TYPE], [STATEMENT_ID], [STATEMENT_REUSE_COUNT], [DETAIL_TYPE], [STATS_TIME], [COMMENT]
FROM   [AX_SQLTRACE]
ORDER  BY [CREATED_DATETIME] DESC


—  HIDDEN_SCANS_QUERIES

— ————————————————————–
— Find Dynamics AX queries that only seek on DataAreaId
— NOT USEFUL for other products
—————————————————————–

SELECT TOP 100 *
FROM   HIDDEN_SCANS_CURR_VW
ORDER  BY TOTAL_ELAPSED_TIME DESC


—  OPTION_FAST_QUERIES

————————————————————————-
— Find queries option(fast) set that have sort operations
—  Dynamics AX only query

— Either we don’t have an index to match the order by clause
—  or the query is potentially to complex for SQL to pick that index
————————————————————————–

SELECT TOP 100 *
FROM   QUERY_STATS_CURR_VW
WHERE  SQL_TEXT LIKE ‘%OPTION(FAST%’
       AND QUERY_PLAN_TEXT LIKE ‘%PhysicalOp=”Sort”%’
ORDER  BY TOTAL_ELAPSED_TIME DESC


—  USER_SCANS_QUERY

— ————————————————————–
— Find Dynamics queries that are scanning
—————————————————————–

SELECT TOP 100 *
FROM   USER_SCANS_CURR_VW
ORDER  BY TOTAL_ELAPSED_TIME DESC
