—   AX_LONG_RUNNING_QUERY_TRACE
—
— ————————————————————–
— Find long running queries from Dynamics AX with source code
— requires client tracing being enabled on the AOS configuration
—
— The AX Long running trace functionality must be enabled for
— ths table to populated.  Either run the DYNPERF_Set_AX_User_Trace_on
— SQL Job or run the script in DynamicsAX Client Tracing.sql
—
–NOTE: Versions prior to AX2012 must enable AX client tracing on the AOS servers

—  HIDDEN_SCANS_QUERIES

— ————————————————————–
— Find Dynamics AX queries that only seek on DataAreaId

—  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
