We’re using JCo 3.0 to connect to RFCs and read data from SAP R/3. We use one RFC RFC_READ_TABLE often and use a second custom RFC to read employee information. My questions revolve around a third RFC RSAQ_REMOTE_QUERY_CALL. I'm calling an ad-hoc query I built in SAP using this RFC but I’m not getting the expected results. The main problem is that it appears that SAP is ignoring one of my selection criteria and using what was saved in SAP when I originally built it. The date criterion stored in my ad-hoc is 6/23/2013. If I pass in 6/28/2013 from JCo, I get the same results as if I had passed 6/23/2013 from JCo.
We have built several ad-hoc queries whose only criteria is a personnel number and call them successfully using RFC RSAQ_REMOTE_QUERY_CALL.
Background on my ad-hoc query: reporting period of today, joining together four aspects of an employee’s information: their latest action (hire, rehire, etc.), organization (e.g. company), pay (e.g. pay scale level) and communication (e.g. email). The query will run every workday.
Here are my questions:
My ad-hoc has three selection criteria. The first two are simple strings. The third is a date. The date will vary each time the query runs. We are referencing the first criteria using SP$00001, the second with SP$00002 and the third with SP$00003. The order of the criteria changes from the ad-hoc to SQ01 (what was SP$00001 in the ad-hoc is now SP$00003). Shouldn’t we reference them in the order defined in the ad-hoc (e.g. SP$00001)?
The two simple string selections are using OPTION “EQ”. The date criteria is using OPTION GT (greater than). Is “GT” correct?
We have some limited accessibility to SAP. Is there a way to see which SP$ parameters are mapped to which criteria?
If my ad-hoc was saved with five criteria but four of them never change when I call the ad-hoc from JCo, do I just need to set the value of the one or do I need to set the other four as well?
Do I have to call this ad-hoc using a variant (function.getImportParameterList().setValue(“VARIANT”, “VARIANT_NAME”))?
Does the Reporting Period have an impact on the date criteria? I have tried changing the Reporting Period to be PNPBEGDA = today and PNPENDDA = today and noticed no change.
Is there a way in SAP to get a “declaration” of your ad-hoc (name, inputs, outputs, criteria)? I have looked at JCoFunction.toXml() and JCoFunctionTemplate. These are good if you want to see something at runtime before it goes to SAP, but I’m looking for something I can use on the JCo end to help me write Java code that matches the ad-hoc.
I have looked at length on the web for answers to my questions and have not found anything that is useful. If there is anything which would help me, please let me know.
Thanks,

Since I don't know much about SQnn, I won't be able to answer all of your questions...
I don't know, sorry.
It should be, at least it's the usual operator for greater than.
Yes - set an external breakpoint right inside the function module and trace its execution while performing the RFC call. Warning: At least basic ABAP knowledge required.
I don't know, sorry.
I don't know either, sorry.
That would depend on the query, I suspect...
JCo won't be able to help you out there - it doesn't know about queries, it only knows function modules. There might be other RSAQ_* function modules to get that information though.
I played with setting up a variant in SQ01 for my query. I added some settings in the variant that solved my problem and answered several of my questions in my post. The main thing I did was add a dynamically calculated date as part of my criteria. Here's how:
1. In SQ01, access menu "Go To" -> "Maintain Variants".
2. Choose your variant and in subobjects, choose "Attributes" and click "Change".
3. In the displayed list, find your date criterion.
4. Choose "D" in Selection Variable, choose a comparison option (mine was GT for greater than), and a "Name of a Variable" (really, this is the type of dynamic date calculation you need).
5. Go back to the Subobjects panel, choose "Values" and click "Change".
6. Enter any other criteria you need in the "Program selections" section.
7. Save the variant.
By doing this, I don't need to pass anything into the query from JCo. Also, SAP will automatically update the date criteria you entered in step #4 above.
So to to answer my questions from my original post:
1 and 4. It doesn't matter because I'm no longer passing anything in from JCo.
2. "GT" is Greater Than.
3 and 7. If anyone knows, I'd really like to find out.
5. Use the name you as it is in SAP (step #2 above).
6. I still don't know, but it's not holding me up.
I'm posting this in case anyone out there needs this type of information. Thanks to Esti and vwegert for helping me out.

I'm making a time-spending tracker based on the work I do every hour of the day.
Now, suppose I have 28 types of work listed in my tracker (which I also have to increase from time to time), and I have about 8 significance values that I have decided to relate to these 28 types of work, predefined.
I want that, as soon as I enter a type of work in cell 1 - I want the adjacent cell 2 to get automatically populated with a significance value (from a range of 8 values) that is pre-definitely set by me.
Every time I input a new or old occurrence of a type of work, the adjacent cell should automatically get matched with its relevant significance value & automatically get populated in real-time.
I know how to do it using IF, IFS, and IF_OR conditions, but I feel that based on the ever-expanding types of work & significance values, the above formulas will be very big, complicated, and repetitive in the future. I feel there's a more efficient way to achieve it. Also, I don't want it to be selected from a drop-down list.
Guys, please help me out with the most efficient way to handle this. TUIA :)
Also, I've added a snapshot and a sample sheet describing the problem.
Sample sheet
XLOOKUP() may work. Try-
=XLOOKUP(D2,A2:A,B2:B)
Or FILTER() function like-
=FILTER(B2:B,A2:A=D2)
You can use this formula for a whole column:
=INDEX(IFERROR(VLOOKUP(C14:C,A2:B9,2,0)))
Adapt the ranges to your actual tables in order to include in the second argument all the potential values and their significances
This is the formula, that worked for me (for anybody's reference):
I created another reference sheet, stating the types of work & their significance. From that sheet, I'm using either vlookup, filter, xlookup.Using gforms for inputting my data.
=ARRAYFORMULA(IFS(ROW(D:D)=1,"Significance",A:A="","",TRUE,VLOOKUP(D:D,Reference!$A:$B,2,0)))
Firstly apologies if this has been answered elsewhere.
I am using QuantLib (via Excel) to build a "standard" bond pricing sheet: prices, yields, spline AND matched-maturity ASW.
I can price the bonds, and have successfully built a forecast (Euribor) and discount (EONIA) curve. I can use qlMakeVanillaSwap() to define a spot-start swap by tenor (eg "1y","2Y" etc) and it works fine. However I am struggling to define a "broken date" swap, ie one which starts T+2 and ends on a given date (and so usually has a short stub on the first payment), to match the bond maturity. All the examples I can find have integer year tenors.
I would be grateful if someone could point me to the right method (can be in python, C++ or Excel). Or do I have to go down the route of creating explicit fixed and floating rate schedules for the swaps?
The answer seems to be: Yes, I do have to create explicit fixed and floating rate schedules, using qlSchedule(), but it turns out to be not too onerous. NB. I am pricing a vanilla EUR ABB vs 6m Euribor swap.
As for pricing, it seems the qlMakeVanillaSwap() is doing a few helpful things in one call, but only IF your swap has a whole-period tenor (eg "1y"). I found the answer for what I wanted to do in the example sheet that came with the QuantLibXL download package.
The other thing that qlMakeVanillaSwap() is doing (in addition to creating the schedules) is setting the Pricing Engine (which is used to discount the cashflows). In the longer version you have to (a) set it yourself using qlInstrumentSetPricingEngine() and (b) pass the result of that call to the Trigger parameter of qlVanillaSwapFairRate(), to establish the calculation order.
After going through the documentations of Utplsql 3.0.2 , I couldn't find any references the assertion api as available in the older versions. Please let me know whether is there a equivalent assertion like utassert.eqtable available in newer versions.
I have just recently gone through the same pain. Most utPLSQL examples out there are for utPLSQL v2. It transpires appears that the assertions have been deprecated, and have been replaced by "Expects". I found a great blog post by Jacek Gebal that describes this. I've tried to put this and other useful links a page about how unit testing fits into Redgate's Oracle DevOps pipeline (I work for Redgate and we often get asked how to best implement automated unit testing for Oracle).
I don't think you can compare tables straight away, but you can compare cursors, which is quite flexible, because you can, for instance, set-up a cursor with test data based on a dual query, and then check that against the actual data in the table, something like this:
procedure TestCursorExample is
v_Expected sys_refcursor;
v_Actual sys_refcursor;
begin
-- Arrange (Nothing really to arrange, except setting the expectation).
open v_Expected for
select 'me#example.com' as Email
from dual;
-- Act
SomeUpsertProc('me', 'me#example.com');
-- Assert
open v_Actual for
select Email
from Tbl_User
where UserName = 'me';
ut.expect(v_Actual).to_equal(v_Expected);
end;
Also, the example above works in Oracle 11, but if you're in 12c, apparently things got even easier, because you can use the table operator with locally defined types.
I've used a similar solution to verify that certain columns of a row were updated, while others were not. You can easily open a cursor for the original data, with some columns replaces by the new fixed values. Then do the update. Then open a cursor with the new actual data of all columns. You still have to write the queries, but it's way more compact than querying everything into variables and comparing those individually.
And, because you can open the 'expected' cursor before doing the actual 'act' step of the test, you can be sure that the query with 'expected' data is not affected by the test itself, and can even base that cursor on the data you are going to modify.
For comparing the data, the cursors are serialized to XML. This may have some side effects. In the test example above, my act step didn't actually do anything, so I got this difference, showing the count as well as showing the missing data.
If your cursors have more columns, and multiple difference, it can sometimes take a seconds to spot the differences between the XML tags. Also, there are currently some edge-case issues with this, I think because of how trimming works in XML.
1) testcursorexample
Actual: refcursor [ count = 0 ] was expected to equal: refcursor [ count = 1 ]
Diff:
Rows: [ 1 differences ]
Row No. 1 - Missing: <EMAIL>me#example.com</EMAIL>
at "MySchema.MyTestPackage", line 410 ut.expect(v_Actual).to_equal(v_Expected);

I want to answer this question:
Does the average time on page A (or more accurately page group A) affect the conversion rate of goal B?
So far in the GUI I have:
A) Created an advanced segment of Time on Page >= 120 ("per hit" option):
http://grab.by/tKOA
B) Modified the segment to also add a filter for Page = regex matching my group:
http://grab.by/tKOU
...But I don't know if this gives me the results I'm after; that is, if they are accurate
I have some other ideas, including assigning the page group as a funnel step and then segmenting by the Time on Page; still waiting on data to come in for that one
Wanting to know if there was a better solution or if I'm on the right track
Drewdavid,
Your approach is quite smart and correct, I would say, however keep in mind that in this context, you are mixing different scopes:
Time on Page is page-level metric
Page seen is visit-level dimension
What you would get in your report is the average time on page calculated from all the pages there were seen during visits which met the regex condition set in the filter (that's what segment does, it included all the pages, not just those that you want to filter). I know this can be confusing, but see this article that gives more examples and goes into greater detail.
To achieve what you are after, remove the segment filter and simply use the advanced filtering above the report table (and choose exactly the same regex you mentioned in your question).
Hope this helps!
When we fire a SQL query like
SELECT * FROM SOME_TABLE_NAME under ORACLE
What exactly happens internally? Is there any parser at work? Is it in C/C++ ?
Can any body please explain ?
Thanks in advance to all.
Short answer is yes, of course there is a parser module inside Oracle that interprets the statement text. My understanding is that the bulk of Oracle's source code is in C.
For general reference:
Any SQL statement potentially goes through three steps when Oracle is asked to execute it. Often, control is returned to the client between each of these steps, although the details can depend on the specific client being used and the manner in which calls are made.
(1) Parse -- I believe the first action is actually to check whether Oracle has a cached copy of the exact statement text. If so, it can save the work of parsing your statement again. If not, it must of course parse the text, then determine an execution plan that Oracle thinks is optimal for the statement. So conceptually at least there are two entities at work in this phase -- the parser and the optimizer.
(2) Execute -- For a SELECT statement this step would generally run just enough of the execution plan to be ready to return some rows to the client. Depending on the details of the plan, that might mean running the whole thing, or might mean doing just a very small fraction of the work. For any other kind of statement, the execute phase is when all of the work is actually done.
(3) Fetch -- This is when rows are actually returned to the client. Generally the client has a predetermined fetch array size which sets the maximum number of rows that will be returned by a single fetch call. So there may be many fetches made for a single statement. Of course if the statement is one that cannot return rows, then there is no fetch step necessary.
Manasi,
I think internally Oracle would have its own parser, which does parsing and tries compiling the query. Think its not related to C or C++.
But need to confirm.
