How to find better SQL log in OBI Answers?

Question

While I have an error in making an OBI request in Answers page, the error message in the result tab is usually not very helpful, like:
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27005] Unresolved column: "Sales Facts Current Month"."Amount Sold (000) Current Month". (HY000)
SQL Issued: {call NQSGetQueryColumnInfo('SELECT "Sales Facts Current Month"."Amount Sold (000) Current Month", "Sales Facts"."Amount Sold", Calendar."Calendar Month Desc", Calendar."Calendar Month Name", Products."Prod Category" FROM SH')}
SQL Issued: SELECT "Sales Facts Current Month"."Amount Sold (000) Current Month", "Sales Facts"."Amount Sold", Calendar."Calendar Month Desc", Calendar."Calendar Month Name", Products."Prod Category" FROM SHI then go to Session Monitor, and click the View Log link. By doing so, sometimes, I got the full sql statement. That is good and I can figure out the problems. Sometimes, I have things like:
-------------------- SQL Request:
SET VARIABLE QUERY_SRC_CD='Report',SAW_SRC_PATH='/shared/sh/Learn';SELECT Times."Calendar Month Name" saw_0, Times."Calendar Month Desc" saw_1, Products."Prod Category" saw_2, Salesfacts."Amount Sold" saw_3, REPORT_SUM(saw_3 BY saw_0, saw_1), REPORT_SUM(saw_3 BY ) FROM SH WHERE (TOPN(Times."Calendar Month Id",40) <= 40) AND (Channels."Channel Desc" = 'Direct Sales') ORDER BY saw_1, saw_0, saw_2
+++Administrator:13290000:1329000f:----2009/09/29 09:18:33
-------------------- General Query Info:
Repository: Star, Subject Area: SH, Presentation: SH
+++Administrator:13290000:1329000f:----2009/09/29 09:18:33
-------------------- Cache Hit on query:
Matching Query:     SET VARIABLE QUERY_SRC_CD='Report';SELECT Times."Calendar Month Name" saw_0, Times."Calendar Month Desc" saw_1, Products."Prod Category" saw_2, Salesfacts."Amount Sold" saw_3 FROM SH WHERE (TOPN(Times."Calendar Month Id",40) <= 40) AND (Channels."Channel Desc" = 'Direct Sales') ORDER BY saw_0, saw_1, saw_2
Created by:     AdministratorThis does not help as the selected tables are not fully spell out. It appear like that OBI find the sql in cache and did process the request fully.
Is there a way I can force OBI resend the request? Is there a way to get OBI log the full sql statement? That way I can copy the sql to SQL*Plus and find exactly the problem
Thanks.

Physical SQL is not visible as it hits the cache.
you can :
1) clear the physical cache from rpd and re-run the request.
or
2) copy the logical SQL, go to web Admin - issue SQL--paste the logical SQL there, then just change one parameter or two, so it does not hit the cache. E.g. change a filter to Feb from Jan...or just add a dummy column at the beginning as select 1 or select 'a' ....rest of the sql same.
this way you can avoid hitting the cache and see the sql (at the bottom of the results - view log)
make sure you have checked the presentation server cache option and set the log level to 4 or more to see details.
