Source table for view QRYSTAT in Netezza - sql

Question

I'm currently working in a Netezza environment on Aginity Workbench and I was planning on using some of the columns from the Management View _V_QRYSTAT to populate a graph in MicroStrategy.
Unfortunately, I cannot get MicroStrategy to recognize any of the columns in _V_QRYSTAT. I don't think that it can read columns from views, and I figured that the best way around this would be to find out which table the _V_QRYSTAT view is getting its data from, but I can't figure out a way to find the source table of a view in Netezza. Does anyone know a method that can be used in Netezza on Aginity Workbench for locating the source table of a view (specifically _V_QRYSTAT)?
I'm very new to SQL, Netezza and MicroStrategy, so I apologize if I am being unclear. Let me know if further elaboration is needed.

Answer 1

I'm pretty sure that MicroStrategy will recognize and work with views, but to answer your question directly, you can see the view definition by querying the _V_VIEW system view.
select definition from _v_view where viewname = '_V_QRYSTAT';
DEFINITION
---------
SELECT
QS.QS_SESSIONID,
QS.QS_PLANID ,
QS.QS_CLIENTID ,
CASE
WHEN ((VU.OBJID NOTNULL
)
OR ("CURRENT_USEROID"() = 4900
)
)
THEN QS.QS_CLIIPADDR
ELSE "NAME"(NULL::"VARCHAR")
END AS QS_CLIIPADDR,
CASE
WHEN ((VU.OBJID NOTNULL
)
OR ("CURRENT_USEROID"() = 4900
)
)
THEN QS.QS_SQL
ELSE TEXT(NULL::"VARCHAR")
END AS QS_SQL ,
QS.QS_STATE ,
QS.QS_TSUBMIT ,
QS.QS_TSTART ,
QS.QS_PRIORITY,
QS.QS_PRITXT ,
QS.QS_ESTCOST ,
QS.QS_ESTDISK ,
QS.QS_ESTMEM ,
QS.QS_SNIPPETS,
QS.QS_CURSNIPT,
QS.QS_RESROWS ,
QS.QS_RESBYTES
FROM
((DEFINITION_SCHEMA."_T_QRYSTAT" QS
LEFT JOIN DEFINITION_SCHEMA."_T_SESSCTX" SS ON (
(QS.QS_SESSIONID = SS.SESSION_ID
)
))
LEFT JOIN DEFINITION_SCHEMA."_V_USER" VU ON (
(SS.SESSION_USERNAME = VU.USERNAME
)
));
(1 row)
This will almost certainly take you a couple of recursions down, as the view you are interested in is based on either views as well as tables.
