Incrementing a variable in a loop

I'm trying to increment my text_item names with a "counter" in my code. Is there a way to do this in PL/SQL? I have 8 text_items I'm trying to fill with a text delimited file. Please see comment within code below.
loop
idxval:= instr( bigstr, ',' );
if idxval = 0 then
smlstr:= bigstr;
else
smlstr:= substr( bigstr, 1, idxval - 1 );
bigstr:= substr( bigstr, idxval + 1 );
end if;
-- increment :text_item name here (8-0) with idxval
:text_item := dbms_output.put_line( smlstr );
exit when idxval = 0;
end loop;
Thanks, Maggie

If you trying to concatenate values to a text_item you should do :
:BlockName_Text_Item := :BlockName_Text_Item || smlstr
It is no necessary use dbms_ouput in forms you just do
:BlockName_Text_Item := smlstr

Problem while incrementing a variable in Jasper Reports

Hi
I am using Jasper Reports for designing reports. These reports will be used by my Java application.
But there is problem while I am trying to increment a variable depending on some condition.
Requirement: I have to display information about all the residents in a hospital in a single report. Resident information will be fetched from the XML file. When a resident ID is found in the XML, then the variable(resno) shoud be incremented. I have set the initial value to 1.
Problem: Only for the first resident, resno is showing as 1. For all the remaining residents, its showing as 0 (zero).The variable 'resno' is not incrementing for each resident.
Even the ResidentID is not null. All the ResidentID's exists in the XML file.
Please find the code below.
<variable name="resno" class="java.lang.Integer" incrementType="Group" incrementGroup="residentbrk" calculation="Count">
<initialValueExpression><![CDATA[new Integer(1)]]></initialValueExpression>
</variable>
<group name="residentbrk" isStartNewPage="true">
<groupExpression><![CDATA[$F{ResidentID}]]></groupExpression>
<groupHeader>
<band height="16">
<textField hyperlinkType="None">
<reportElement positionType="Float" x="0" y="-1" width="96" height="17"/>
<textElement>
<font isBold="true"/>
</textElement>
<textFieldExpression class="java.lang.String"><![CDATA[$R{residentno}]]></textFieldExpression>
</textField>
<textField hyperlinkType="None">
<reportElement positionType="Float" x="96" y="-2" width="64" height="18"/>
<textElement/>
<textFieldExpression class="java.lang.Integer"><![CDATA[$V{resno}]]></textFieldExpression>
</textField>
</band>
</groupHeader>
</group>
Could you please provide a solution for this.

Not clear at all. May be like this
declare
v_temp varchar2(100);
v_final number;
begin
--loop
v_temp:='sun';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_temp := v_temp || 'Mon5.1';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_temp:= v_temp || 'Tue';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_final:=to_number(v_temp);
dbms_output.put_line('v_final'||v_final);
--coalesce
--end loop;
end;

Problem using local variable in event loop

I have a state machine from which I want to monitor various controls, including "Start" and "Stop" buttons. Not every state needs to monitor the controls. At present, most states run timed loops. In the first state that reads the front panel, I have an Event structure (inside a While loop) that monitors the various controls' Change Value events. For numeric controls, I update variables (in shift registers) as needed. The "Start" button is used to end the While loop controlling the Event structure, allowing the State to exit to the next state.
My problem comes in subsequent states that employ this same idea. Here, I put a Local Variable bound to the Start button and use the same code, but it frequently happens that when I enter this particular state, I cannot "turn on" the control -- I push the button, but it stays off. Curiously, if it was On when I enter, I can turn it off, but then I'm stuck not being able to turn it on.
I mocked up a very simply routine that illustrates this. There are two sequences (corresponding to the two states). Both use an Event loop with a local variable bound to my Stop button (really this is an LED control with custom colors). I've deliberately moved the "initialization" (the declaration of the control in the block diagram) out of the Event loops -- putting it inside the first loop modifies the behavior in another strange way.
Here's my thinking on how I would expect this to work: The code outside Event Loop 1 should have little effect. Assume the Stop button is initially Off. You will "sit" in Event Loop 1 until you push the Stop button, changing its value to True; this value will be passed out of the Event case and cause the first While loop to exit. You now enter the second sequence. As I understand the Exit tunnel, it defaults to "False", so I'd expect to stay in the second Event loop until I turn the Stop button from On to Off, which will pass out a False, and keep me in the While for one more button push. However, this doesn't happen -- I immediately exit, as though the "True" value of the Stop local variable is being seen and recognized by the Event loop (even though it hasn't changed, at least not in the context of this second loop).
An even more curious thing occurs if I start this routine with the Stop button turned on. Now I start in my Event loop waiting for a change, but this time the change will be from On to Off, which won't cause an exit from the frame. This will be reflected by having the While loop count increment. We should now be in the state of the example above, i.e. in an Event loop waiting for the control to be pushed again, and turned On. However, clicking the control has no effect -- I cannot get it to "turn on".
Where am I going astray in my thinking? What is it about this method of doing things that violates the Labview paradigm? As far as I can tell, what I'm doing is "legal", and I don't see the flaw in my reasoning, above (of course not -- otherwise I'd have fixed it myself!). Note that because I'm using local variables inside Event loops (and I'm doing this because there are two places in my code where I want to do such testing), the Stop control is not latching (as required). Is there something that gets triggered/set when one reads a latched control? Do I need to do this "manually" using my local variable?
I'll try to attach the simple VI that illustrates this behavior.

Actually, that's OK. NOT OK is having multiple event structures in the same sequence structure.

That's interesting. I had always thought I read more messages discouraging such a thing rather than saying it was okay. Your link lead me to another thread with this message. http://forums.ni.com/ni/board/message?board.id=170&message.id=245793#M245793. Now that thread was mainly concentrating on registered user events which would be a different, but related animal.
So if you have 2 event structures they each have their own event queue? So if you have a common event, one structure pulls it off its event queue and it does not affect the other structure's event queue? I guess the inherent problem with this particular VI was that the second event structure locked the front panel. Since the code never got to that 2nd event structure because the first loop never stopped because the change was from true to false. After reading your post and the others, I did some experimentation and turned off the Lock front panel on the 2nd structure, and that prevented the lockup of the program.
Overall, the example VI still shows problems with the architecture and I think your answer should put the original poster on the right track. I think as a rule I would probably never put the same event in multiple structures, I feel there are better ways to communicate the same event between different parts of a program, but I learned something by reading your reply and about how the event structures work in the background. Thanks.

How can I increment a variable in LabView ?

Hello ..
I'm trying to use LabVIEW to increment a variable, but I can't find the right way to do that !
I need to declare a variable and assign zero as its value, then increment it by one each time a certain condition is met, and I need it to reset to zero after it reaches a certain value. It's easy to perform these steps using standard C language but here it looks complicated !
Could someone explain the steps to do that ?
Thanks!

I guess trying to explain how to write a state machine would be difficult..
It should take you 5 mins to implement the solution. I post so late that it's probably too late for you.
But here goes.
Take a While loop with shift registers as shown in the image of an earlier post. Place a Case Structure inside the loop. You will need to use an enumerator (usually create a type def control). Put 2 states into the enumerator: reset, increment. Wire the enumerator to the question mark of the Case Structure. In the increment case of the Case Structure, you place the +1. In the reset case you simply wire zero '0' as the proper type (dbl, U32, etc) to the right tunnel of the Case Structure.
In the code somewhere... you need to set the logic to tell the state machine when to reset. I don't recall reading what that was... But in any case, you need another shift register to pass the next state to the Case Statement. Or if that code is embedded into some other code, then it is probably not necessary. But you will need someting like a selector to choose between Increment and Reset. Also choose which of the 2 is the default state, probably any of the 2 for now. The outcome of the logic to reset or increment is obviously wired to the middle terminal of the Select.
Just curious, since you are in this predicament. Did you tell your boss that you knew LabVIEW in order to get the job and now you are obviously stuck delivering a solution?

Difference between Pre and Post Incrementing a variable

I have a problem understanding the nuances between i++ and ++i.
I have run several loops and changed the position of the "++". I noticed that sometimes the out put differs and sometimes the output remains the same.
Is there a rule of thumb as to whether a variable show be post or pre incremented?
Thanks

Thank you all.
After I asked the question, I did a little research and found this (from JGuru shortcourse):
Note that x++ and ++x are equivalent in standalone contexts where the only task is to increment a variable by one,that is, contexts where the ultimate evaluation is ignored:
int x = 4;
x++; // same effect as ++x
System.out.println("x = " + x);
This code produces the output:
x = 5;
The next part after this is:
In the following context, the placement of the increment operator is important:
int x = 4;
int y = x++;
int z = ++x;
System.out.println(
"x = " + x + " y = " + y + " z = " + z);
This code produces the output:
x = 6 y = 4 z = 6
======================================================================
I thought the out put would be x = 4, y = 6, z = 4.
I totally lost! How do I interpet this correctly?

Using variables in a loop

Hello and thanks in advance! I'm attempting to insert records into a temp table using a loop. I have many declared variables that will be used as criteria in the query. Since the variable are all named the same other than a ascending
numberic to the name, how would I get a variable in a loop to substitute the "numberic" part of the variables? I've created some sudo sql for what I'm trying to achieve:
Declare @Start1 as Date = '2014-01-01'
Declare @Start2 as Date = '2014-15-01'
Declare @Start3 as Date = '2014-18-01'
Declare @i INT = 1
WHILE @i < 20
     SELECT .... INTO #MyTemp ...
     WHERE OrderDate Like @Start + @i       --This is the line I cant seem to get working.
     SET @i = @i +1
END

Auto increment variable in foreach loop in ssis

i know this has been asked N number of times, but still i have a question for you guys
i have files sitting in FTP location
i am loading the data from the files into tables (no issues)
but i need to assign value to a particular column as -99999999 and then auto increment that number while loading the files into the database
I cannot have auto increment for the that particular column
should i use a derived column, script component, execute sql task?
can somebody point me to the right direction
if it were a single file, assigning the auto incremental number is easy, but with for each loop, i am not able to get the solution
Thanks

Hi Jack,
To achieve your goal, you can use a Row Count Transformation in the Data Flow Task to get row count for each file, and then use an Execute SQL Task after the Data Flow Task to update the total row count variable. Supposing the variable used in the Row Count
Transformation is InsertCount, the variable used to store the total row count is TotalInsertCount. We need to set the ResultSet of the Execute SQL Task to “Single row”, and the SQLStatement to:
DECLARE @Insert_Count INT, @Total_Insert_Count INT
SET @Insert_Count=?
SET @Total_Insert_Count=?
SET @Total_Insert_Count=@Total_Insert_Count + @Insert_Count
SELECT R_Total_Insert_Count=@Total_Insert_Count
Then, set the Parameter Mapping of the Execute SQL Task, we map variable InsertCount and TotalInsertCount to the parameters in the SQL statement respectively. In the ResultSet page of the Execute SQL Task, map the resultset to variable TotalInsertCount.
Please refer to the following screenshot:

How do I increment a variable at the end of a loop to run it through the loop again?

I'm new to LabVIEW programming and I'm trying to write a small program that just receives a lower and upper limit, and whether the user wants to increment or decrement the number. I can't figure out how to increment the number after the simple calculations have been done and to run through the loop again with the incremented number. Right now I'm using a while loop inside of a case structure where true decrements and false increments.

Here are a few possibilities.

Is it possible to create variables with an incremented name in a for loop?

I want to create a number of variables according to the following:
MyClass var_1 = new MyClass();
MyClass var_2 = new MyClass();
MyClass var_3 = new MyClass();
MyClass var_n = new MyClass();
Is there any way to do this in a loop ? Such as
for ( int iii = 0 ; iii < 10 , iii++ ) {
MyClass var_(iii) = new MyClass();
Thanks

ArrayList<MyClass> list = new ArrayList<MyClass>();
for(int i = 0; i < 10; i++){
MyClass c = new MyClass();
list.add(c);
MyClass [] myClasses = new MyClass[list.size()];
list.toArray(myClasses);
//when use the MyClass instance, use the element of the myClasses array by the index, as myClasses[0],myClasses[1]

Assigning value to array type variable in a loop

Hi
I have a scenario in which i am assigning value from a array type variable(x) to the invoke variable of a database adapter. The variable x is exact replica of the invoke variable.
My copy operation in assign activity looks like this-
<copy>
<from variable="Var" part="InputParameters"
query="/ns7:InputParameters"/>
<to variable="Invoke_call_XXDPI_EDI_852_PKG_InputVariable"
part="InputParameters"
query="/ns7:InputParameters *(* bpws:getVariableData('iterator') *)* "/>
</copy>
It is inside a while loop activity.
PS *()* are square brackets
But it is erroring out at run time.
Does anybody has an alternate idea to assign value to an array type?.
i have seen that while extracting value from an array type variable it works fine
A similar kind of operation is shown below.
<copy>
<from variable="Var" part="InputParameters"
query="/ns7:InputParameters *(* bpws:getVariableData('iterator') *)* "/>
<to variable="Invoke_call_XXDPI_EDI_852_PKG_InputVariable"
part="InputParameters"
query="/ns7:InputParameters"/>
</copy>
Thanks

Hi Ayush
I suppose you are getting some error like "source node returns multiple elements".
In second case there is no problem because you are assigning *InputParameters[bpws:getVariableData('iterator')]* (+suppose InputParameters[1]+) to target. Here it works fine because you are fetching oonly 1 value from source and assigning it to the target.
Now in first case you are saying copy InputParameters to target[1] suppose. You know that source is an array which contains multiple index so which index field from the source will be assigned to the target.
Try your process with only 1 source value it will work but when multiple values will be there it will fail. You have to merge both the cases and it will look like
*<copy>*
*<from variable="Var" part="InputParameters"*
query="/ns7:InputParameters ( bpws:getVariableData('iterator') ) "/>
*<to variable="Invoke_call_XXDPI_EDI_852_PKG_InputVariable"*
part="InputParameters"
query="/ns7:InputParameters ( bpws:getVariableData('iterator') ) "/>
*</copy>*
And the easiest way to do this is by the transform activity as said above.

It would have helped if you had posted your code as CODE but as it is, I could hardly read it. My guess about what you are asking is, if you want a template to return a value, just write that value to the result stream inside the template.
If that wasn't what you were asking, then please post your code in a readable format.

Using the counter to create a input variable in while loops

I'm using a loop to increment oscillator freq on my lock-in. I want this incrementation to be based off the loop counter. But when I do this, it gives me some kind of circular reference error. Can I make my own counter inside the loop instead? How? See the attached screen shot for details.

Hi Jesse,
You can attach a copy of your vi instead of a screen capture, because the the screen capture is difficult to read. Unless there is confidential code, of course.
The first thing I noticed is that there are some improperly wired vi's. I can't comment much because the screen capture was not clear.
However, the "circular referrence error" means that you have a wire which exits a loop and re-enters it.
If you need to pass a value back to the beginning of a loop, then use a Shift Register. Right click on the edge of a loop and select "Add Shift Register". It can be initialized by wiring a value (or control) to the input of the loop.

Assigning element (node) to variable in a loop

Hello,
I will get below input as <Request> .<instance></instance>.... <instance><instance>.. </Request>(see below) to my soa composite process. I have an instance.xsd . I have created an variable Instancexml element of type instance.xsd ,so Instancexml variable can hold all the values in order to utilize attributes,elements in my process.
I have assigned a count for <instance> which is 2 in this case.
I am looping through count and trying to assign first instance xml to Instancexml variable , but when I use this xpath, both instances are getting copied instead of one (when count=1)
bpws:getVariableData('inputVariable','payload',concat('/ns1:Request/ns1:instance[',bpws:getVariableData('j'),']'))
What is the correct xpath?
<Request>
<instance>
<attribute name="abc" type="string"/>
<attribute name="def" type="string"/>
<element1 name="123" type="string">
<element2 name="456" type="string">
<element3 name="888" type="string">
</instance>
<instance>
<attribute name="xyz" type="string"/>
<attribute name="xxy" type="string"/>
<element1 name="223" type="string">
<element2 name="678" type="string">
<element3 name="333" type="string">
</instance>
</Request>

You shouldn't need to do a concat within the XQuery path parameter. Try the following:
bpws:getVariableData('inputVariable','payload','/ns1:Request/ns1:instance[bpws:getVariableData("j")]')

Accessing variable in a loop

I cannot access this variable from outside the loop. I know
it has to be something very simple. When tracing the variable, it
comes back as undefined. Please help.. Thanks

when you prefix a variable with var, you make it local to the
function that contains the variable.
