Controlling program flow and case statements

Hey all, I was wondering, I if I have 40 nested case statements and I want the program to close after they are all done, is it sufficient to wire the "?" for both true and false of the outermost case to the close routine in order to guarantee that all of them will execute? Or is there an even better way using data flow methods?
-Dobbs

I'd recommend state machines better than that way or sequences, to controll dataflow better. Example is attached.

Diff b/w IF/ENDIF and CASE statement?

Hi all,
Plz let me know the difference between IF and CASE statements.Which one is better to be used in general...and are there any specific situations where we have to go for CASE insted of IF.
Rgds,
Reddy.

Hi,
Case statement is good for performance wise because here we declare cases
and according to these cases program will be executed.
When we use if statement then the cursur goes to in the loop, when ever
the loop is not complete till then the programme will not execute.
Thats by in performance basis the case statement is good.
Let me try and explain using an example...
1) For IF statement...
Suppost you have a variable color..and you are checking it against color names.
then your code will be
IF COLOR == 'BLUE'.
    statements
ELSEIF COLOR == 'BLACK'.
    statements.
...and so on....
ENDIF.
But if you use CASE Statement
CASE COLOR.
when 'BLUE'.
   statements.
when 'BLACK'.
statements.
so follows that CASE is easy to use and performance wise is also better.

Priyanka.

Booleans to control programming flow

Is it ok to use booleans within an object to control program flow in an Object Oriented approach?
For eg: I have 2 tables in the database which are related. Some times both the tables need to be updated, other times, just 1 table.
One approach would be to have 2 separate methods in the Data Acces object which handle these situtions, as this seems to be cleaner. However, another approach would be to send all the data along with a boolean to the Data Access Object and let the Data Access object make the decision of which tables to update by checking the boolean.
Please tell me which approach is better and more Object oriented.

1. How often will the Two tables be updated together.(Not a major factor)
2. Keep both methods you mentioned.
3. Create a new method that takes the boolean and the data to update.
and use this in it:
(boolean)?FirstMethod:SecondMethod;
If boolean is true then it calls FirstMethod else SecondMethod.
Anyone else think of anything?

Programming catching exceptions to control program flow.

Hello,
I have the following snippet:
     public List subList(int fromIndex, int toIndex) {
          PGSearchEngineList subList = new PGSearchEngineList();
          for (int index = fromIndex; index < toIndex; index++) {
               try {
                    subList.add(this.get(index));
               } catch (IndexOutOfBoundsException e) {
                    return subList;
          return subList;
     }Notice that I use a try catch to catch a IndexOutOfBoundsException and to control program flow. Is this a bad practice?
Julien Martin.

I believe I read once that you shouldn't code an exception to deal with a condition that you could reasonably expect to occur. There is some sample code for the value list handler on the j2ee patterns page that deals with search result paging in a little "cleaner" way:
http://java.sun.com/blueprints/corej2eepatterns/Patterns/ValueListHandler.html
Hope this helps.

Help with program flow and timing a loop please

I'm working on an application that will display vibration data on several tabs. 1 tab displays the time waveform, another a running RMS value, another an FFT etc.
On another tab I want the user to have the option of streaming the data to disk for 'x' number of seconds.
I created a sub-vi with a flat sequence structure.
The first frame open/creates a file. The second frame gets the current time in seconds and adds 'x' seconds to it. The third frame contains a while loop with a "Get Current Time in Seconds" and a "Write to Binary File" which executes while the current time is less than the "previous current time plus 'x'".
This sub-vi is in a while loop that is called when a "capture data" button is pressed.
My problem is that the rest of the program (waveform, RMS, FFT displays) stops executing when the while loop / sub-vi is executing.
This can be seen via the "TEST" indicator that doesn't update.
When the program flow goes back to the rest of the program I get an error 'cause the buffer has over-flown (ed)
I'm really new at this so any help is greatly appreciated.
I've attached images of the main vi (Project3.pdf) and the sub-vi containing the Flat Sequence (WriteToDisk.pdf)
I can attach the actual vis if it helps.
Thanks,
Erik

The behavior you're seeing is by design. There are two solutions to your problem:
Place the write to file in a separate loop that runs in parallel to your main loop. Thus, your "Project3" VI would have two loops. One is the data acquisition, the other is the streaming to file. You should not create data dependencies between the loops that would cause one loop to wait until the other is done. You want both running in parallel. You can stop both loops with the same stop button. With this method you can use local variables to get the Time Waveform data as you're doing now.
Launch the stream to file VI dynamically. This basically uses the VI Server to start a subVI and then immediately return to the caller. The subVI is then running on its own. There are examples that ship with LabVIEW that show you how to do this. You would have to have the subVI monitor something to determine if it should stop should the main program stop.
The first option would be the easiest to implement in your case. The second is more complex, but leaves you with one loop.

Decode and case statement in the update..

Its is more to it, but I want to check with you guys, the experts on this, this look busy to me, it should be a more simplify way of doing it, do you think will work
The government decide to change the ethnic codes, and we have to come with certain rules to in our report, anyway, do you think this will work? again It is more to it I declare my variables, this is just one part of the precedure.

Doesn't look like a right Decode syntax.
DECODE (col1,'VAL1','This','VAL2','That','ElseThis')
means
--Psuedocode
IF col1 = 'VAL1' THEN 'This'
IF col1 = 'VAL2' THEN 'That'
ELSE 'ElseThis'You can use CASE statement Instead of DECODE
CASE

Issue with TableAdapter Configuration Wizard and CASE statements

I am having an issue with using any CASE statements in the select clause for the Table Adapter Configuration Wizard (TCW). I can take any query without a CASE and it will run fine, but inserting any CASE statement in the Select such as:
SELECT
(CASE WHEN :ras_sort = 'D' THEN TO_CHAR(a.TRANS_DATE,'YYYYMMDD')
WHEN :ras_sort = 'C' THEN c.CLAIMDEP_NAME
WHEN :ras_sort = 'A' THEN TO_CHAR(a.ACCOUNT_NUMBER)
END) sort1
FROM xxxx
causes the TCW to error with "error in list of function arguments, 'THEN' not recognized" and several other errors. I have tried with and without parameters in the CASE and have tried both forms of the CASE statement. I have tried multiple queries, all that run with no problem outside of TCW and ODP, but this seems to be a real issue
Is this a known problem and are there any workarounds that will allow use of the TCW?
Thanks,
Dave

Hi Ashish,
perhaps you launch the Web service wizard from the wrong location (i.e. not selecting the SEI you want to use). Did you strictly follow the steps described in the <a href="http://help.sap.com/saphelp_nwce10/helpdata/en/44/f36fa8fd1d41aae10000000a114a6b/frameset.htm">documentation</a> for creating the web service?

CURSOR and CASE STATEMENT

Hello All:
Is it possible to have the CASE Statement in the cursor? If so, could you please show me how to use it? I tried to use it as following but it did not work on Form Builder. I tried it on Oracle SQL *Plus and it worked there.
CURSOR tbl_chck_cur IS
SELECT chck_id,
NVL(sup_chck_id,'') sup_chck_id,
(CASE WHEN sup_chck_id = null THEN
(SELECT order_no from tbl_chck_lk where tbl_chck.chck_id = tbl_chck_lk.chck_id ) ELSE
(SELECT order_no from tbl_chck_lk
where tbl_chck.chck_id = tbl_chck_lk.chck_id ) END) order_no,
FROM tbl_chck;
Thanks in advance for any help.
KT

First, get rid of that NVL on sup_chck_id. It does nothing. What do you want it to do, anyway???
And what is the second table "Tbl_chk_sub" in the from clause?
Ignoring tbl_chk_sub, this might work:SELECT T1.chck_id,
       T1.sup_chck_id,
       Decode(T1.sup_chck_id, null,LK1.order_no,Lk2.order_no) order_no
FROM tbl_chck T1,
       tbl_chck_lk LK1,
       tbl_chck_lk LK2
where LK1.chck_id(+)     = T1.chck_id
    and LK2.sup_chck_id(+) = T1.sup_chck_idIf the above does not work, you will have to find a work-around -- either do the lookup select in the post-query trigger, or create a stored function you can call from the select that returns the correct order_no based on the two columns, sup_chck_id and chck_id.
Do you know if we can use the SELECT statement inside the CASE statement?Sometimes Forms are several steps behind in adapting new sql features. So it looks like you cannot at this time.

Excel and CASE statement.

Hello Experts,
I am using a CASE statement on CHAR column as follows:
CASE WHEN Sales.Ret='Y' THEN 'Returning' ELSE 'New' END
It gives an error: Odbc driver returned an error (SQLExecDirectW).
Whereas when I use another CASE statement with Numrical column it is working perfectly.
CASE WHEN Sales.Amount<40 THEN 40 ELSE 100 END
Am i missing some Excel data source setting related to CHAR data type?
My source is MS Excel 2003 and OBIEE is 10.1.3.4.1
Appreciate any comment, help.

Hello Saichand,
I would like to reconfirm that the CASE statement with Numeric column is working with EXCEL as source.
The strange thing is that the CASE statement with CHAR column was also working! and from one fine day it it started throwing an error (i thought some source setting might got changed inadvertently ).
Thank you for your response but I would like to see comments/suggestions from other experts..

It is not allowing me to use column alias in the checksum
How do I do this ?
Gus

Well, you could either put the CASE statement in the checksum parameter as well (duplicating logic = bad) or use a factored subquery with the case statment in and alias that column, then reference it in the main query (logic in one place = good).
Cheers

How do I use switch and case statements to fill more than one other field?

Hi all,
I'm new to the community.
I'm trying to make an existing form more user friendly for my coworkers. I want to use a switch and case approach in a drop-down list field so that the selection fills two seperate other fields with different info related to the selection.
I can already do this with one field, but if I add a second target field under an existing case the text doesn't appear there when I make the selection from the dropdown.
Basically, I'm asking if I can do this:
switch
(sNewSel){
   case "1": // Selection 1    Row2.Field1
= "text for field 1";
    Row1.Field2 = "text for field 2";
    break;
etc.
It works if the "row1.field2" option isn't there, but not when it is present.
Any takers?

I'm not sure if I will be able to send you the form. There may be too much to redact.
Would this last bit of code in the cell affect anything?
if
(bEnableTextField)
{Row2.Field1.access
= "open"; // enable field
Row2.Field1.caption.font.fill.color.value= "0,0,0"; // set caption to black
That is, do I also need to repeat the same thing for the second target cell (Row1.Field2)?
What would be possible hang ups that would prevent it from working correctly?
Dave
By the way, I'm not sure if my other attachment posted. I am trying again.

WHERE 1=1
but i'm getting error:
00937. 00000 - "not a single-group group function"
Any idea how I can change my query to get results? When I'm using group by repo_status, I'm getting two rows, but that isn't a good result for me

Solution:

Joel,
This is statement that I got an error on. The invalid character error was on line 9:
and doc.CRED_RPT_RCPT_IND='Y'
I do not see any invalid character on this line. So, I am stuck now.

SWITCH and CASE STATEMENT

i am trying to use switch statement for drawing different shapes by clicking shapes buttons (eg line ,rectangle oval etc) . i have got a method called setDrawMode and i am passing shape value as parameter to this method but nothing happen .all it is doing is drawing with default value.
my code for clicking button:
String s = event.getActionCommand();
if (s.equalsIgnoreCase("LINE"))
{   mycanvas.setDrawMode(0);}
else if (s.equalsIgnoreCase("RECTANGLE"))
{ mycanvas.setDrawMode(1);}
else if (s.equalsIgnoreCase("OVAL"))
{ mycanvas.setDrawMode(2);}my setDrawMode method:
public void setDrawMode(int mode)
switch (mode)
case LINE :
case RECTANGLE:
case OVAL:
this.mode = mode;
break; default:
throw new IllegalArgumentException();
}my code for paint method:
public void paintComponent(Graphics g)
super.paintComponent(g);
if (numPoints>0)
for (int i=0; i<numPoints-1; i+=2)
switch (mode)
case LINE:
g.drawLine(p.x,p[i].y,p[i+1].x,p[i+1].y);
g.drawLine(p[numPoints-1].x,p[numPoints-1].y,cx,cy);
break;
case RECTANGLE:
g.drawRect(p[i].x,p[i].y,p[i+1].x,p[i+1].y);
g.drawRect(p[numPoints-1].x,p[numPoints-1].y,cx,cy);
break;
case OVAL:g.drawOval(p[i].x,p[i].y,p[i+1].x,p[i+1].y);
g.drawOval(p[numPoints-1].x,p[numPoints-1].y,cx,cy);
break;
values for shapes
int LINE = 0
int RECTANGLE = 1
int OVAL = 2
please help
khurram

what is the point of this switch here?
public void setDrawMode(int mode)
     switch (mode)
         case LINE :
         case RECTANGLE:
         case OVAL:
         this.mode = mode;
         break;
         default: throw new IllegalArgumentException();
} This dosn't do anything but asign mode to the global mode, which is why you get the same value every time. You need to do something in the switch and you don't have a break between them so they would all execute anyway. You can try this.
public void setDrawMode(int mode)
     switch (mode)
         case LINE : this.mode = 0;
         break;
         case RECTANGLE: this.mode = 1;
         break;
         case OVAL: this.mode = 2;
         break;
         default: throw new IllegalArgumentException();
}But if your just trying to set a global mode you could just ommit the switch because its redundant
public void setDrawMode(int mode)
       this.mode = mode;
       // then you could call paint however you call it
       paintComponent(this.getGraphics);
}

Query cost and CASE statement

Hi, I'm working on a performance issue for a customer.
I'm tuning some suspect SQL that uses complex DECODE statements to perform IF/THEN/ELSE logic.
I've taken a statement and rewritten it using CASE however what I've noticed is the cost of the query execution plan has increased dramatically as a result. N.B. I haven't changed the WHERE clause of the query as yet, just replaced one DECODE with the equivalent CASE.
The db version is 9.2.0.4. Does anyone know of issues with the performance of CASE as opposed to DECODE. I'm wondering should I leave the DECODEs as is even though they're way too complicated.
Tks,
Paul.

Here's an example of a DECODE:
nvl(count(distinct decode
(decode(sign(ords.dwh_created_date_id-:v_start_cycle_id),1,1,0,1,-1,0) *
decode(sign(:v_end_cycle_id-ords.dwh_created_date_id),1,1,0,1,-1,0),1,ords.dwh_order_id,NULL)),0) calc1
The equivalent CASE I've coded is:
NVL(COUNT(DISTINCT(CASE WHEN (ords.dwh_created_date_id BETWEEN :v_start_cycle_id AND :v_end_cycle_id)
THEN
ords.dwh_order_id
ELSE
NULL
END)),0) calc1
I've been doing further testing with an amended WHERE clause and did run both CASE and DECODE versions. The performance difference between the two was negligible. So it seems (as I'd hoped) that the amendment of the execution path doesn't appear to be affected by CASE even though Oracle reports the query cost of it is higher.
It is slightly confusing though. Is the query cost in this case a red herring ?
