How to processing the results from the select statement in SQL query?

Hi
This might be too simple, but my knowledge of the SQL is very limited...
I have table where I do have details from calls (Lync QoE).
I can take all calls from the table, but I would like to count the concurrent calls on the table. This is how I got it work on the Excel to work (but I would like to do that on the SQL statement to get it more dynamic use):
Table have these line and this is what I get out from the Select):
[callid],[start],[end]
1ABC,1.1.2014 01:00:15, 1.1.2014 01:01:00
5DEF,1.1.2014 01:00:45, 1.1.2014 01:05:00
FDE2,1.1.2014 01:03:15, 1.1.2014 01:04:00
KDJ8,1.1.2014 01:04:15, 1.1.2014 01:06:00
FDJ8,2.1.2014 01:04:15, 2.1.2014 01:06:00
KDSE,3.1.2014 01:04:15, 3.1.2014 01:06:00
The information I would like to get, is what is the maximum amount of the concurrent calls per day.
On the excel I basically count line by line how many concurrent calls each line have had, and then pickup the highest one. On above example the calls 5DEF, FDE2 and FDE2 have been active at the same time which gives 3 for the first day.
The table is ordered by the start. So let say the code is on the third line (FDE2). I need to count calls from before which end time is after the start time (of FDE2), but also I need to count calls after (FDE2) which are started before the current
call has ended.

Count the number of rows resulting from a select statement

Hi,
Is there any way of counting the number of rows resulting from a select statement. i.e I have a select distinct statement and I then want to perform an IF statement on the number of rows resulting from the select statement.
Any help appreciated
Thanks
Gary

Declare
var1 number;
Begin
select count(distinct column_name) into
var1 from table_name;
If var1 > x Then
End IF;
End;
Hope I understood the problem correctly

If the result from the stored procedure returns 0 rows I get this error returned:

If the result from the following stored procedure returns 0

Why would you want to extract all of the results from the database and write them to a table just so you could read them back out again? Wouldn't it be simpler just to return the results in one shot?
In general the procedure and call would look something like this:
SQL> create or replace procedure myprocnamehere
2     ( p_results out sys_refcursor )
3 as
4 begin
5     open p_results for
6        select 'Results here' as results from dual;
7 end;
8 /
Procedure created.
SQL> var myresultset refcursor
SQL>
SQL> call myprocnamehere(:myresultset);
Call completed.
SQL> print :myresultset
RESULTS
Results here
1 row selected.Edited by: William Robertson on Feb 8, 2011 7:13 PM

How can i prevent the result from the user until he does a specific action

hi again
1-i have created two textfields for the user to enter two names
2-i have created a result button when the user hit it a result will appear
in any case if the user hits the result button the result will appear
even if he does not enter the two names
i want to make the result available only if the user enters the two names
by checking the inputs before the result appear
if he enteres the names the result appear
if he does not enter an error message appear?
how can i do that process?

lol i think he was talking about formating your messages on the forum.
look at an example that i just created hope it helps. If not then read up on the GUI chapter of your java book.
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JTextField;
import java.awt.BorderLayout;
public class ButtonTest{
    public static void main(String args []){
        JFrame frame = new JFrame();
        JPanel panel = new JPanel();
        final JTextField textA = new JTextField(10);
        final JTextField textB = new JTextField(10);
        JButton button = new JButton("Perform Action");
        class Listener implements ActionListener{
            public void actionPerformed(ActionEvent e){
                if(!textA.getText().equals("") && !textB.getText().equals("")){
                    System.out.println(textA.getText()+" "+textB.getText());
       ActionListener listener = new Listener();
        button.addActionListener(listener);
        panel.add(textA);
        panel.add(textB);
        panel.add(button);
        frame.getContentPane().add(panel,BorderLayout.SOUTH);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.show();
}

How do I return the results of two SELECT statements in to one result?

I want to do this without using UNION.
Here's an example of what I'm trying to do:
I have a table called COUNTRY with the following columns:
COUNTRY
COUNTRY_CODE
DATE_VISITED_LAST
POPULATIONI have another table called STATE_COUNTY with the following columns:
STATE_COUNTY
COUNTRY_CODE
STATE_COUNTY_CODE
DATE_LAST_VISITED
POPULATIONI have a third table called TOWN with the following columns:
TOWN
COUNTRY_CODE
STATE_COUNTY_CODE
TOWN_CODE
DATE_LAST_VISITED
POPULATIONNow through the interface I have, a user will supply a country code. I need a SELECT statement that will return a table with the following result set:
The COUNTRY_CODE entered including the DATE_LAST_VISITED and POPULATION for this country
------> All the associated STATE_COUNTY's belonging to this country along with the DATE_LAST_VISITED and POPULATION for each STATE_COUNTY_CODE.
-------------> All the associated TOWN_CODE's belonging to this state_county and country along with the DATE_LAST_VISITED and population for each TOWN.
So the table will have 9 columns:
COUNTRY
DATE_LAST_VISITED_COUNTRY
POPULATION_COUNTRY
STATE_COUNTY
DATE_LAST_VISITED_STATE_COUNTY
POPULATION_COUNTY
TOWN
DATE_LAST_VISITED_TOWN
POPULATION_TOWNAny ideas how this can be done?
Thanks.

Hi guys,
Would it be ok to do it like this (with a join):
SELECT
     c.country_code,
     c.date_last_visited AS DATE_LAST_VISITED_COUNTRY,
     c.population AS POPULATION_COUNTRY,
     s.state_county_code,
     s.date_last_visited AS DATE_LAST_VISITED_STATE_COUNTY,
     s.population AS POPULATION_COUNTY,
     t.town_code,
     t.date_last_visited AS DATE_LAST_VISITED_TOWN,
     t.population POPULATION_TOWN,
FROM
     country c
     LEFT OUTER JOIN state_county s ON s.country_code = c.country_code
     LEFT OUTER JOIN town       t ON t.country_code = s.country_code
AND                                       t.state_county_code = s.state_county_codeThe results required would be something like:
Country_Code     DATE_LAST_VISITED_COUNTRY     POPULATION_COUNTRY     STATE_COUNTY_CODE         DATE_LAST_VISITED_STATE_COUNTY         POPULATION_COUNTY     TOWN_CODE     DATE_LAST_VISITED_TOWN     POPULATION_TOWN

How to JOIN the results of multiple SELECT statements

Hello,
I currently have a table where each row represents a single census date for a given tag number, where each tag number can have multiple census dates and data which are represented by their own row in the table.
I currently have 2 SELECT statements that select all tag numbers given a census date, and would like to combine those 2 queries so that the data is presented in a manner such that for each tag number, instead of obtaining 2 rows for each tag number, I would be presented with 1 row for each tag number consisting of three columns: tag_number, data1, and data2.
Both of the requested dates are not necessarily present for all tag numbers, and in the event that only one date is present, the other column should contain null, but if both dates are not present for a given tag number, the tag number is omitted.
The two queries I would like to JOIN are:
SELECT a.tag_number, a.data AS data1
FROM tab1 a
WHERE
a.census_date='11/21/2009'and
SELECT b.tag_number, b.data AS data2
FROM tab2 b
WHERE
b.census_date='11/24/2009'The table from which I am selecting the data looks like such:
tag_number census_date     data
    1       11/21/2009      10
    1       11/23/2009      11
    1       11/24/2009      12
    2       11/19/2009      13
    2       11/21/2009      14And the data that I would like to result looks like:
tag_number data1           data2
    1       10              12
    2       14              nullAny help would be greatly appreciated.
Thank you in advance,

Hi,
This looks like a job for pivot
SELECT       a.tag_number
,       MAX (CASE WHEN a.census_date = TO_DATE ('11/21/2009'
                                                   'MM/DD/YYYY'
               THEN a.data
            END
           )          AS data1
,       MAX (CASE WHEN a.census_date = TO_DATE ('11/24/2009'
                                                   'MM/DD/YYYY'
               THEN a.data
            END
           )          AS data2
FROM      tab1    a
WHERE       a.census_date IN ( TO_DATE ( '11/21/2009'
                                  , 'MM/DD/YYYY'
                   , TO_DATE ( '11/21/2009'
                                  , 'MM/DD/YYYY'
GROUP BY a.tag_number
;Comparing DATEs to stirngs, like '11/24/2009', is simply asking for trouble.
Always use a conversion function (like TO_DATE) or DATE literals instead.

How do I get results from the LMS?

I have created an assessment with click boxes, and question slides in Captivate3. I place the course on our LMS (CornerstoneOnDemand) and users can take the course, see their score at the end, and if they pass, the course is marked completed. That is all working.
What I want to know is how can I know which questions people are getting wrong?
In Captivate I noticed Objective ID and Interaction ID fields on the Reporting tab for the click boxes, so I am thinking I could put in an name/label that would make sense so I know which question (clickbox) is what.
Is a file created that stores all this information (user's input, selections, results)? If so, what is that file, how do I access it, what is it called?
Please help.
Larena

I'm not using your LMS, but a LMS based on Blackboard. When the option 'Interactions and Score' is activated in CP-Quiz settings, the gradebook in Blackboard can be used to open for each student the file associated with his score. In this file you'll find all answers, but it helps if you use some meaningful identifiers for the items. It is also possible to download the result files for all the students. I believe this should be a functionality of the LMS/SCORM but cannot help you with the name of the file.

Pass the results from a selection formula to the default values for a parameter field

Post Author: kevans
CA Forum: General
Crystal 10 u2013 SQL 2000
I want to create a parameter field that will display all of our IT Departments so the end user can select the one they want to run the report against, such as IT-Security, IT-Network, etc. about 40 in all. BUT I donu2019t want this to be a static list where I type in all 40 depts in the default list, I was hoping I could do something more dynamic such a formula field that says u201C if {group.name startswith u2018ITu2019 then {group.name}u201D and then have the parameter field pull from this source.
Iu2019m sure this has been answered in a previous post but Iu2019m not finding it. I see stuff on creating a record selection formula such as u2018if {?group} like u2018IT-Secur*u2019 thenu2026u201D but this leaves too much room for error if people donu2019t type the name correctly. Maybe Iu2019m not using the record selection formula correctly? Sorry if I offend anyone but I just upgraded from 8 to 10 and thought for sure this option would be in 10, perhaps built right into the parameter default value page where you can place in select criteria but NOTHING has changed.

Post Author: sharonmtowler
CA Forum: General
if you are creating the parameters in the rpt file, it will only pull values you enter, or directly from the database
in the record selection you can do something like this, so if they only enter the first 2 characters it should pick up only the IT etc.
(if eft(,2)={?parameter} then true else ={?parameter})

Can't retrieve the result from the soap response

We are trying to send and retrieve audio files using j2me web services. What we did is to convert the byte array (recorded audio) to hex string before sending it to the server. We used the sun java platform 9 for our web service, sun java wireless toolkit 2.2,mysql.
We successfully saved and sent audio files that is recorded up to 39 seconds long. Longer than that, the application does not continue running the program. In retrieving the audio file from the database, the application could retrieve and play an audio file up to 2 seconds long. Any audio file longer than 2 seconds, the application does not complete the retrieval.
We already looked on the memory usage of the emulator and it doesn't use the whole phone memory to retrieve a 3 seconds audio file. We also looked on the soap message response and it showed that it retrieves the whole audio file which is in hex string even if it is a 3 seconds audio file.
We don't know why the phone/emulator could not retrieve the whole audio file (if it's longer than 2 seconds) from the server. What could be the cause of the problem?

How to add process model results to the sequence file results?

After my sequence file runs, I would like to add some additional results using the process model. I need to log my equipment list which is obtained by the process model. Alternatively, I could add a sub-sequence to the end of each of my sequence files for doing this, but that would create maintenance problems if I ever needed to change the way equipment is logged. Does anyone know a way to (1) append process model results to the sequence file results or (2) force each client sequence file to call a sub-sequence before returning to the process model.

Mark -
The report and database process model routines expect a single subsequence step result that invoked MainSequence. This result contains the results from the sequence call.
In TestStand after the process model root sequence call to MainSequence is performed, the property Locals.ResultList[0] is the MainSequence result. The subproperty Locals.ResultList[0].TS.SequenceCall.ResultList contains the results from the steps in MainSequence.
One option is to create a subsequence call in the process model that logs the equipment info in the results for its steps. The call to the subsequence should not be checked to record results.
This subsequence would have a parameter called ResultList. The Result type does not exist in the Insert menu, so you can only create the parameter by copying the empty Locals.ResultList and pasting it in the parameters. Then change its type from By Value to By Reference.
In the setup of the subsequence, add the following steps which do not record results. These steps rename the Locals.ResultList parameter to ResultListOrig, and then create a new Locals.ResultList alias property that really references Parameters.ResultList. This way any additions to the Locals.ResultList really append to the Parameter.ResultList.
Setup
Step: "Rename Locals.ResultList"
StepType, Adapter: Action, Active-X
Description:
Action, Set PropertyObject.Name = "ResultListORIG"
Record Results: False
Step: "Create Alias in Locals"
StepType, Adapter: Actioin, Active-X
Description:
Action, Call PropertyObject.SetPropertyObject ("ResultList",
0x201 ' Not Owning and Create, Parameters.ResultList)
Record Results: False
In the Main steps, you add your equipment info steps which record results.
In the Cleanup steps you undo the steps performed in Setup.
Cleanup
Step: "Delete Alias in Locals"
StepType, Adapter: Action, Active-X
Description:
Action, Call PropertyObject.DeleteSubProperty ("ResultList",
0x400 ' Refer to Alias)
Record Results: False
Step: "Rename Locals.ResultListORIG"
StepType, Adapter: Action, Active-X
Description:
Action, Set PropertyObject.Name = "ResultList"
Record Results: False
I have attached a TS 2.0 version of SequentialModel.Seq that has a AppendResults subsequence in it and this is invoked after MainSequence in Single Pass entry point.
Hope this helps...

How do i put the results from a calculation as the offset value

hi .. i am trying to set the value of the mask offset from the results i get from a calculation.
this is what i am trying to do
i want to get a ROI from an image, so i used thresholding to separate it form the background
then i find the centroid of the image. i then create a mask a little
larger than the ROI to get rid of the background in an unthresholded
image but the position of the mask is at origin(0,0)
i need the centroid of the mask to be the same as the ROI. so i
subtract the x and y values of the ROI centroid with the centroid of
the mask to get the offset. which is done manually. but i want to
do it for ROIs in different positions, so i want to get the value of
the subtraction staight into the VI .. how can i do that..?? i tried
wiring the value of subtraction into the input of the "set offset" node
but it does not work .. can anyone help me ??thanks very much

i managed to get it done...i did not know how about the cluster to element function .. could you comment on my program?
i'm trying to construct a sign language translator. for the
signing. i am using yellow colored gloves with colored finger tips. the
yellow region is to help me detect the position of the gloves during
thresholding.
1st of all .. i do thresholding to separate the ROI from the
background.. then i put a bouding box around the region of interest. is
there any better and easier way to do this??
could anyone point me in the right direction ?
i am very new to LV and image processing. i always have problem
using some functions especially when it requires lots of settings.
sometimes the help file does no help much ..
my next problem after creating the bounding box is how do i extract
only the colors from the image? i tried color thresholding but the
result is gray scale. how do i extract only the yellow region of the
gloves and the finger tips to be further processed? in MATLAB , color
segmentation is used.. but i can't figure how it works in LV .. please
help me .. thanx

How do I search scanned documents that Adobe Reader reads but shows 0 results from the search?

How do I search scanned documents that Adobe Reader reads but shows 0 results from the search?

If the scanned document was not processed for OCR, then it is just an image and cannot be searched for text.

In VB how do I pass my low and high limit results from a TestStand Step into the ResultList and how do I retrieve them from the same?

I am retrieving high and low limits from step results in VB code that looks something like this:
' (This occurs while processing a UIMsg_Trace event)
Set step = context.Sequence.GetStep(previousStepIndex, context.StepGroup)
'(etc.)
' Get step limits for results
Set oStepProperty = step.AsPropertyObject
If oStepProperty.Exists("limits", 0&) Then
dblLimitHigh = step.limits.high
dblLimitLow = step.limits.low
'(etc.)
So far, so good. I can see these results in
VB debug mode.
Immediately after this is where I try to put the limits into the results list:
'Add Limits to results
call mCurrentExecution.AddExtraResult("Step.Limits.High", "UpperLimit")
call mCurrentExecution.AddExtraResult("Step.Limits.Low", "LowerLimit")
(No apparent errors here while executing)
But in another section of code when I try to extract the limits, I get some of the results, but I do not get any limits results.
That section of code occurs while processing a UIMsg_EndExecution event and looks something like this:
(misc declarations)
'Get the size of the ResultList array
Call oResultList.GetDimensions("", 0, sDummy, sDummy, iElements, eType)
'Step through the ResultList array
For iItem = 0 To iElements - 1
Dim oResult As PropertyObject
Set oResult = oResultList.GetPropertyObject("[" & CStr(iItem) & "]", 0)
sMsg = "StepName = " & oResult.GetValString("TS.StepName", 0) & _
", Status = " & oResult.GetValString("Status", 0)
If oResult.Exists("limits", 0&) Then
Debug.Print "HighLimit: " & CStr(oResult.GetValNumber("Step.Limits.High", 0))
Debug.Print "LowLimit: " & CStr(oResult.GetValNumber("Step.Limits.Low", 0))
End If
'(handle the results)
Next iItem
I can get the step name, I can get the status, but I can't get the limits. The "if" statement above which checks for "limits" never becomes true, because, apparently the limit results never made it to the results array.
So, my question again is how can I pass the low and high limit results to the results list, and how can I retrieve the same from the results list?
Thanks,
Griff

Griff,
Hmmmm...
I use this feature all the time and it works for me. The only real
difference between the code you posted and what I do is that I don't
retrieve a property object for each TestStand object, instead I pass the
entire sequence context (of the process model) then retrieve a property
object for the entire sequence context and use the full TestStand object
path to reference sub-properties. For example, to access a step's
ResultList property called "foo" I would use the path:
"Locals.ResultList[0].TS.SequenceCall.ResultList[].Foo"
My guess is the problem has something to do with the object from which
you're retrieving the property object and/or the path used to obtain
sub-properties from the object. You should be able to break-point in the
TestStand sequence editor immediately after the test step in question
executes, then see the extra results in the step's ResultList using the
context viewer.
For example, see the attached sequence file. The first step adds the extra
result "Step.Limits" as "Limits", the second step is a Numeric Limit (which
will have the step property of "Limits") test and the third step pops up a
dialog if the Limits property is found in the Numeric Limit test's
ResultList. In the Sequence Editor, try executing with the first step
enalbled then again with the first step skipped and breakpoint on the third
step. Use the context viewer to observe where the Limits property is added.
That might help you narrow in on how to specify the property path to
retrieve the value.
If in your code, you see the extra results in the context viewer, then the
problem lies in how you're trying to retrieve the property. If the extra
results aren't there, then something is wrong in how you're specifying them,
most likely a problem with the AddExtraResult call itself.
One other thing to check... its hard to tell from the code you posted... but
make sure you're calling AddExtraResult on the correct execution object and
that you're calling AddExtraResult ~before~ executing the step you want the
result to show up for. Another programmer here made the mistake of assuming
he could call AddExtraResult ~after~ the step executed and TestStand would
"back fill" previously executed steps. Thats not the case. Also, another
mistake he made was expecting the extra results to appear for steps that did
not contain the original step properties. For example, a string comparison
step doesn't have a "Step.Limits.High" property, so if this property is
called out explicitly in AddExtraResult, then the extra result won't appear
in the string comparison's ResultList entry. Thats why you should simply
specify "Step.Limits" to AddExtraResul so the Limits container (whose
contents vary depending on the step type) will get copied to the ResultList
regardless of the step type.
I call AddExtraResult at the beginning of my process model, not in a UI
message handler, so there may be some gotcha from calling it that way. If
all else fails, try adding the AddExtraResult near the beginning of your
process model and see if the extra results appear in each step's ResultList.
Good luck,

How to get the values from html:select? tag..?

i tried with this, but its not working...
<html:select styleClass="text" name="querydefs" property="shortcut"
             onchange="retrieveOptions()" styleId="firstBox" indexed="true">
<html:options collection="advanced.choices" property="shortcut" labelProperty="label" />
</html:select>
                    <td align="left" class="rowcolor1">
                    <script language="javascript" type="text/javascript">
                          function retrieveOptions(){
                         var sel = document.querydefs.options;
                         var selectedOption = sel[sel.selectedIndex].value;
                         document.write(selectedOption);
                       </script>

<td align="left" class="rowcolor1">
                    <script language="javascript" type="text/javascript">
                          function retrieveOptions(){
                         var sel = document.querydefs.options;
                         var selectedOption = sel[sel.selectedIndex].value;
                         document.write(selectedOption);
                       </script>This java script is not working at all..its not printing anything in document.write();
This is code..
<td class="rowcolor1" width="20%">
<html:select styleClass="text" name="querydefs" property="shortcut"
                         onchange="retrieveSecondOptions()" styleId="firstBox"
                         indexed="true">
                         <html:options collection="advanced.choices" property="shortcut"
                              labelProperty="label" />
                    </html:select>i tried with this also. but no use..i'm not the getting the seleced option...
function retrieveOptions(){
firstBox = document.getElementById('firstBox');
                         if(firstBox.selectedIndex==0){
      return;
    selectedOption = firstBox.options[firstBox.selectedIndex].value;
}actually , how to get the values from <html:select> ...?
my idea is to know which value is selected from the combo box(<html:select> ) if that value is equal some string i have enable a hyperlink to open a popup window
