Questions on Merging Dis-similar Data Types...

I am using Web-I version 11.5.8.834 (We do not use the Crystal Reports module, all of our reports are built with Web-I).
I have two questions:
Question 1: First I am attempting to create a report from two different universes and need to merge a dimension from each universe. The two dimensions have similar data, but one is set up as a "string", and the other universe has the same data set up as a "number". Our IT department creates and maintains the universes and I have requested that one of the dimension data type be changed to match the other, but I am told that other users have already set up reports using these dimensions and to change them at this point might cause a problem with their reports. So my first question is: Can two separate dimensions be setup within a single universe, using the same data field, each having different data types (e.g., a field with numeric data be set up as a "string" and a second dimension be setup as a "number")? If this works, I can make a recommendation to our IT department to do this and I will not have to resort to Question 2. but just in case, here is Question 2:
Question 2: I have two other dimensions that I might be able to use, but it requires creating a variable and "trimming" data off of each of the fields. The first universe is a part number with three alpha characters followed by four numeric characters (PRT1234). The second universe has a serial number, in which the first four characters match the last four characters of the other universe (1234-00111). If I trim off the first three characters from the first universe using a variable (=right([Part_Number];4), and trim off the last six characters from the second universe using a variable (=left([Serial_Number],4), the variables will have matching data. The second question is: Can variables be merged? I've tried, but it isn't working so far. If so, can someone give me some hints on how to do it?

Charles,
Can variables be merged?
No, local variables cannot be merged. The manipulation must be performed at the database level via Designer before the data comes across to the report. As an aside, your IT deparatment can create "new" objects just for you, placed in the list under a separate sub-class that manipulates the data to your liking and will not upset other users who already built reports using the original columns of data. I guess my point is that you can have multiple objects placed in your universe that derive from the same column in a given table -- user A has it per their flavor and user B has it per his flavor.
Thanks,
John

How can I calling LabView DLL within LabView and pass similar Data Types?

I am trying to use an Instrument Driver, which is created in LabView6.1 as a DLL. At this point I have only LabView to test this DLL. I was wondering, is there easy way to find out what sort of Parameter or Data Type I should be using.
How can I pass the following data with in LabView:
LVRefnum as Type?
LVBoolean as Type?
TD1 (a structure) as Type?
It is funny to see that I am able to create a DLL in labview but having trouble calling it within LabView. I thought, it would be easier to test the DLL within the same environment.
Basically, I am more worried about the VISA calls that are used in the driver to communicate with instrument. Because, there is no link to �VISA32.dll� in
the header file, is that handled by the LV Run-time engine? I guess more details are needed on using the LabView DLL within LabView from National Instrument Technical Support.

A LVRefNum seems to be an unsigned long data type (32bit). You can cast it
in LV then use that as a parameter to call the DLL. (an Occurrence type
seems to be a Ulong32)
When you created the DLL what was the resulting type for the LVRefNum?

Data Type for Process Flow... PB with Date?

I've got a problem by passing parameters in process flow.
I have a mapping with a parameter DATE_EXEC (data type : DATE) and a default value that is TO_DATE('20/01/2007' , 'dd/mm/yyyy') . My mapping is working good when i launch it.
I have a process flow which contains the mapping. This process has a parameter DATE_EXEC (data type : DATE). I bind the 2 DATE_EXEC. But when i launch my mapping the value is not recognized, I try with :
- TO_DATE('20/01/2007' , 'dd/mm/yyyy')
- 20/01/2007
- 2007.01.20
- 2007-01-20
My question is what are the data type in process flow? They are not ORACLE TYPE.
For example , a parameter in a mapping which is a VARCHAR2 must be input between quotes but if you bind it to a parameter of a process flow which is a STRING (not ORACLE Data type) , you must input it without quotes?
Anybody has some rules about that?
I apologize for my english, i'm a french people.

Here is some information on the literal quote or not quote query and what I think you need to do at the end, hope it helps. Not exactly intuitive...since the flow designer (you) have to know what is a PLSQL object and what is not.
1. Literal = FALSE
When Literal = FALSE is set then the value entered must be a valid PL/SQL expression which is evaluated at the Control Center e.g.
'Hello World!'
22 / 7
2. Literal = TRUE
When Literal = TRUE then the value is dependent on the the type of Activity. If the activity is a PL/SQL object i.e. Mapping or Transformation, then the value is PL/SQL snippet. The critical difference here is that the value is macro substituted into the call for the object. The format of the value is identical to that entered as default value in the Mapping editor. e.g.
'Hello World!'
sysdate()
If the activity type is not a PL/SQL object then the value is language independent. e.g.
Hello World
3.1427571
What you should try......
Check the map activity parameter in your process flow to see if literal is false (an expression), set it to false and then try using your TO_DATE('20/01/2007' , 'dd/mm/yyyy') expression, deploy your flow and execute. Alternatively the user guide defines the DATE type for flow with the format YYYY-MM-DD so you can have the parameter value as '2007-01-20' use literal equal to true and remember and quote your value.

Performance issue while using data type 'STRING'.

Hello All,
I have created a table for storing values of different features coming under a particular country. Since the last field 'Value field' have to hold text upto 800characters for some features, i have used the data type 'String' with character length specified as 1000. I am able to store values upto 1000characters using this. Also, the table has to hold lots and lots of value, and it will increase in future also.
Since i have mentioned the data type as 'String', I have one doubt whether this will affect the performance. Because length of most of the values in my value field is less than 75characters and in some case only it will exceed 700characters. So, my question is whether the 'String' data type will allocate the length which am specifying in the table for each entries, though the values entering is less than the specified length.
For example, if the value of my value field is 'Very High Complexity' which is of length 20characters, will the space allocation be reduced to 20 or will it be still 1000characters?
Hope someone can clarify my doubt.
Thanks In Advance,
Shino

Hi Shino,
Well it is possible to store using STRING or LCHR in the transparent tables. There are some underlyning facts here:-
1. You can only have one such field per table
2. You cannot view them in the se11 / se16 table content browser
3. You will need to maintain an additional field for storing the length of the STRING or LCHR field.
Regarding the performance:
even though ABAP allows storing STRING or LCHR type fields in the transparent tables but as soon as the lenght of the field crosses 255 chars it is not advisable to store it directly in the transperant tables.
You should store that field in the knowledge repository and only a pointer to the knowledge repository in the transperant table field.
Anyways, Since you have only one field with such a requirement then i would suggest you use STRING instead of LCHR as in LCHR you will have to mandatorily assign a length (like 1000) so even if you are storing only 20 chars or 300 chars the system will reserve a slot of 1000 chars; this is not with string as in case of string everything would be dynamic.
The result being that the reading time increases in case of LCHR.
I Hop this answered your question.

Sagar.

Custom data type causing trouble in deploying shared variable to RT target

I seem to be having some difficulty in using a network published shared variable created from a custom data type when deployed as an executable on an RT cRIO target. I'll start by describing why I believe this is where the problem lies. I created my RT VI in the LabVIEW development environment (LV 2012) and everything works fine. This VI is pretty simple because it rapidly devolved in to a debug exercise. The RT VI starts by simply blinking the User LED a couple of times and then starts a simple acquisition loop to read a few values off the hardware using the scan engine (while still blinking the User LED). After reading the hardware, the values are bundled in to a cluster and written to a network-published shared variable defined by a type def custom control. The custom control contains five dbl precision floats. If it matters, the cRIO RT system hosts the shared variable in this case.
So, I deploy this under the development environment and everything works fine. The LED blinks merrily along, telling me that the program is running properly. Running a host VI that reads the network-published shared variable yields the desired result. All is good.
Now I want the cRIO system to run this simple program autonomously at startup. I build it, set it as the startup VI, deploy it and then restart the cRIO target. The LED never starts blinking... the VI does not seem to run. I will spare you most of the debugging work and jump to the end. I basically "Diagram Disabled" various sections of code until the VI started running correctly as an executable. I kept reducing the size of the disabled code until only one thing was disabled: the write to the custom data type shared variable.
So, I guess my question is this: Are custom data types defined by type def'd custom controls allowed in executable RT programs? I've read through the cRIO Developers Guide, my NI Real Time Development course book and the Using Shared Variables white paper and I didn't see anything that forbade it. I know that there are some things not allowed in executables that are allowed in the development environment (front panel property nodes, dialog VIs, OS-specific calls, etc), but no mention of custom data type shared variables. Any ideas as to why my VI runs in the development environment but fails when compiled unless I remove the write to the network published shared variable?
Thanks in advance for your help!!
Solved!
Go to Solution.

Paolo,
So I thought that you meant to disconnect them in the build specification. Under the Additional Exclusions in the build specification, there is a check box for Disconnect Type Defs. I checked that box, recompiled, redeployed and it did not work. At this point I had to give and move forward, so I was going to convert the data typed from a cluster to an array. When I went in to change the data type in the shared variable pop-up from the project explorer, there was a big button under the variable definition that "Disconnect from Type Def". Clicked that button, recompiled, redeployed, restarted and everything worked great. Thank You!!
I suspect that I'll have to be careful if I change the definition of that data type (add an element, etc) since it is no longer connected to the data type. We'll cross that bridge when we need to.
Thanks again

Few questions - game loop, data types, speed

Hello, I have a few questions after studying some topics in this forum regarding game creation:
1) What's the fastest way to wait in the game loop? I've seen two approaches:
thread.sleep(10)andsynchronized(this) { wait(10); }2) What data types shall I use? In C++ I use to prefer int over short in all cases, because 32bit hardware works faster with integers. Is this same on cell phones?
3) Speed of applications is slow. I just wonder wheter it's my fault. I was testing application, which only cleared the buffer and outputted FPS and I got around 20 frames. It was Nokia 6300 with 240x320 display. After testing on other phones I've found out that the bigger the resolution, the slower the game is going. Is this normal?
Thanks for replies...

1) You're not going to notice any really speed difference between the two code snippets. Read up on 'Threads', and you'll see why one may be used in place of the other depending on the situation. In general there may be a slight performance loss, however unnoticable, when using the synchronized version, but when you are multithreading it is likely necessary.
sleep(int) is impossible to interrupt, so it's generally a no-no in most situations. However we are talking about devices where every bit of performance helps, so as long as it works for ya, it's not a big deal.
2) The performance difference is fairly negligable, if any. The biggest thing to consider is memory requirements, and shorts take 1/2 the data.
Also, many phones don't support floating point data types, so you'll likely need to use ints/longs to calculate your values if you want to have any accuracy beyond whole numbers. Doing something like shifting bits or using 1000x values in your calculations can get around most of the problems when you can't use floats.
3) The biggest performance killers are IO, memory allocation, screen drawing; pretty much in that order. So I imagine that you are re-creating a new String object every time you output your FPS value on screen right? Doing that every frame would destroy any hopes of getting high-performance.
Just be careful, and never allocate objects when you can avoid it. anything where you concat String objects using + will cause your performance to die a horrible painful slow death. Remove anything that says 'new' from your main loop, and all String operations, and it'll likely speed things up a lot for ya.
Does your main loop have something like this?
g.drawString("FPS: " + currentFps, 0,0,Graphics.TOP | Graphics.LEFT);
This is very bad because of the String operation. It'll create a new String every frame.
If you have any more specicif questions, or you'd just like to pick the brain of a mobile game dev, stop by my messageboard:

Function returning string. Data type question

Hello all,
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
Our database has a parent record master_member_record_id & and children of those records member_record_id. I wrote a function which returns the master record for the child.
eg. get_master(member_record_id). simple enough.
I have wrote the opposite of this also, get_member_records(master_member_record_id). Obviously this function has multiple records to return so I have it set to return a listagg string with ',' separation. They want to be able to use this function as follows:
select * from member_table where member_record_id in (get_member_records(master_member_record_id));
or something similar, I realize this is a data type issue here, wondering if this is even possible. What do you think?
Thanks in advance for your criticism/help,
Chris

My disagreement is with how pipeline table functionality is used.
Instead of this (what it sounds like the OP is doing but returning CSV format)
create or replace type TClientIdArray is table of number;
create or replace function GetClientIDs( parentID number ) return TClientIdArray is
array TClientIdArray;
begin
select
    client_id bulk collect into array
from master_table
where parent_id = parentID;
return( array );
end;A pipeline would look as follows:
create or replace type TClientIdArray is table of number;
create or replace function GetClientIDs( parentID number ) return TClientIdArray pipelined is
begin
for c in (select
               client_id
             from master_table
             where parent_id = parentID ) loop
    pipe row( c.client_id );
end loop;
return;
end;The first method is in fact more sensible in this case, especially when used from PL/SQL. A single SQL call/context switch to get a list of client identifiers. The issues with the first method are
- cannot effectively deal with a large data set of client identifiers
- would be suboptimal to use this function in subsequent SQL
- if called by a client, a ref cursor (not collection) should be returned
But assuming that the list of client identifiers are needed to be stepped through via complex PL/SQL app processing, using a (small) array is fine (assuming that concurrency/locking is not needed via a FOR UPDATE on the select that identifies the client identifiers to process).
A pipeline in this case does not do anything better. It introduces more moving parts - as a native PL/SQL can no longer be used to get the collection and step through it. A TABLE() SQL function is needed, a SQL statement, and more context switching.
The pipeline is simply an unnecessary layer between the code wanting to use the client identifiers and the SQL statement supplying the client identifiers. This approach of SQL -calls-> PIPELINE -calls-> MORE SQL is invariable wrong - unless the pipeline (PL/SQL code) does something very funky with the data from its SQL call, prior to piping it, that cannot be done using SQL.
If the "user" of that client identifiers is SQL code, then both the above methods are flawed. As this code is already SQL, why use PL/SQL to call more SQL code? Simply use the SQL code/logic that supplies the client identifier list directly in the SQL code that needs the client identifiers. This means something like SQL JOIN, EXISTS, or IN clauses.

Silly data types question involving strings

what sort of data type do I need to do this operation
I want this data to be inserted into table Term: 2002 T2
OracleCommand cmd = new OracleCommand("INSERT INTO FILEONE(Term) VALUES ('2003 T2');", dbConn);
it says I am using an invalid character which I am assuming is to do with data type or the way I am putting together my INSERT statement ...
thanks,
Lance

What is FILEONE?
insert into <TABLE> (<COLUMN>) values ...
So you are inserting into the "term" column of table "fileone".

Data Type questions

I’m passing data values from a 3rd party system into CRMOD. Can you let me know if the below two statements are correct please?
1) WebLink data type: The value I’m passing into this field can just be of type String right?
2) Picklist Values: Are all values in a picklist of type String? If I have a pick list of number like (1, 2, 3, 4), these number values are still of type String right?
Thanks

1 last question. The underlying data type is .... ?

interface MyInterface{}
class MyInterfaceImpl implements MyInterface {}
MyInterface myVar = new MyInterfaceImpl();in the last line is this correct.?
myVar's underlying data type is MyInterfaceImpl and MyInterface is it's actual type?

Anything would be correct.
MyInterfaceImpl myvar = new MyInterfaceImpl();
MyInterface myvar = new MyInterfaceImpl();
The datatype and actual type is MyInterfaceImpl. But you cann access that object using the MyInterface interface.

IDOC - XI - IDOC scenario. I can't import XSD to Data Type

Helo!
I have some problem with creating data tape. I have to create data type similar to IDOC structure which i imported from SAP system. Similar becouse in this DT I need to add some more elements. Becouse the IDOC structure is large I wont to import IDOC structure to this DT automaticly. I try to eksport XSD structure of my IDOC and then import to data type but i can read the monit:
The tag <element> is not allowed at <<xsd:schema><xsd:element><xsd:element>>.
I'm beginer in XSD so I don't now how to change this file.
Can somebody help me on that or explain whot I can do to make this DT.
Thanks for answer!

Hi,
U can import the IDoc XSD to External defination and use it in your Message Mapping and Interfacing Mapping.
There is no need to create a data type of message type for IDoc.
External Defination
<b>External Definition</b> enables you to import a local WSDL, XSD, or DTD file to the Integration Repository and specify which parts of the schema to be used as a description for a message.
U can use this ED as
1.Inbound/Outbound in the Message Interface.
2.Source/Target structure for the Message Mapping.
In a scenario If there is a necessitity for changing the Occurance of some segment of the IDOC steps u perform is.
1.Import the IDoc to XI.
2.Export the IDoc(i.e XSD format) and save it to the local machine.
3.Make changes to the IDoc structure by modifying the XSD file in the local machine.
4.Save it as an XSD file Itself.
5.Import the XSD file in the IR under the External Defination.
6.Use this XSD in your Message Interface/Mapping which is same as IDoc structure but with some changes that u have made.
Go Thru this Blog <a href="/people/michal.krawczyk2/blog/2005/12/04/xi-idoc-bundling--the-trick-with-the-occurance-change Bundling - Trick without BPM</a> BY Michal Krawczyk where the Occurance of the IDoc is changed to 1...Unbounded from 1...999999999 by using the XSD.

Problem accessing basic data types

Hi,
I am a newbie at using JNI so please don't mind if I am asking something trivial.
I have a JNI wrapper for a native C code. The C code is a Gtk+ application using GLib library. This library has it's own basic data types. For example, "gchar" corresponding to "char". I have generated the JNI Wrappers using the tool named "Swig" which is an interface between the C and other programming languages such as Java. What Swig has come up with is since "gchar" is not understood by it as "char" so it has taken the "gchar" as come Reference Type and generated another class for it. And instead of accepting simple char it is expecting a long.
Even if I pass a numerical value like 11111 after instantiating this newly generated gchar class while running the program the JVM is crashing complaining SIGSEGV recieved from the underlying libraries.
I am confused first of all since the error is not understood and secondly how can I tell the JNI that gchar is similar to char.
What approach should I follow to solve the problem that I am facing? Any feedback on this will be appreciated.
Thanks & Regards

At run time you can see all the data........ like what i have shown...
but if you clearly see, DATE will be in the internal format..but if you print it, it will be in dd:mm:yyyy
can you suggest me if i have a dynamic field symbol (table data) ,,,, How can i convert data types dynamically..
if it is a static internal table i am achieving with WRITE TO statement.....but i have huge data in field symbols...
Instead of all these , please specify the exact problem your are facing . What is it with date field ? . In SAP while printing the internal format will be converted to external. What is your requirement with this date field?
My output looks some thing like this:
04 36876 15.09.2011 39600 1999
06 36960 15.09.2011 39600 2632
07 36874 15.09.2011 39541 9232
My expected output
04 36.876 15.09.2011 39.600 1.999
06 36.960 15.09.2011 39.600 2.632
07 36.874 15.09.2011 39.541 9.232
I dont see any problems mentioned in your date field. Both your actual and expected outputs reflects the same in date field.
In SCN you will only get solutions if your question is precise.

Unicode Migration using National Characterset data types - Best Practice ?

I know that Oracle discourages the use of the national characterset and national characterset data types(NCHAR, NVARCHAR) but that is the route my company has decide to take and I would like to know what is the best practice regarding this specifically in relation to stored procedures.
The database schema is being converted by changing all CHAR, VARCHAR and CLOB data types to NCHAR, NVARCHAR and NCLOB data types respectively and I would appreciate any suggestions regarding the changes that need to be made to stored procedures and if there are any hard and fast rules that need to be followed.
Specific questions that I have are :
1. Do CHAR and VARCHAR parameters need to be changed to NCHAR and NVARCHAR types ?
2. Do CHAR and VARCHAR variables need to be changed to NCHAR and NVARCHAR types ?
3. Do string literals need to be prefixed with 'N' in all cases ? e.g.
in variable assignments - v_module_name := N'ABCD'
in variable comparisons - IF v_sp_access_mode = N'DL'
in calls to other procedures passing string parameters - proc_xyz(v_module_name, N'String Parameter')
in database column comparisons - WHERE COLUMN_XYZ = N'ABCD'
If anybody has been through a similar exercise, please share your experience and point out any additional changes that may be required in other areas.
Database details are as follows and the application is written in COBOL and this is also being changed to be Unicode compliant:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
NLS_CHARACTERSET = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET = AL16UTF16

##1. while doing a test convertion I discovered that VARCHAR paramaters need to be changed to NVARCHAR2 and not VARCHAR2, same for VARCHAR variables.
VARCHAR columns/parameters/variables should not by used as Oracle reserves the right to change their semantics in the future. You should use VARCHAR2/NVARCHAR2.
##3. Not sure I understand, are you saying that unicode columns(NVARCHAR2, NCHAR) in the database will only be able to store character strings made up from WE8MSWIN1252 characters ?
No, I meant literals. You cannot include non-WE8MSWIN1252 characters into a literal. Actually, you can include them under certain conditions but they will be transformed to an escaped form. See also the UNISTR function.
## Reason given for going down this route is that our application works with SQL Server and Oracle and this was the best option
## to keep the code/schemas consistent between the two databases
First, you have to keep two sets of scripts anyway because syntax of DDL is different between SQL Server and Oracle. There is therefore little benefit of just keeping the data type names the same while so many things need to be different. If I designed your system, I would use a DB-agnostic object repository and a script generator to produce either SQL Server or Oracle scripts with the appropriate data types or at least I would use some placeholder syntax to replace placeholders with appropriate data types per target system in the application installer.
## I don't know if it is possible to create a database in SQL Server with a Unicode characterset/collation like you can in Oracle, that would have been the better option.
I am not an SQL Server expert but I think VARCHAR data types are restricted to Windows ANSI code pages and those do not include Unicode.

Selecting #of bits for data types in Java

hi,
i would like to know if we can constrain compiler on allocating memory to basic data types, such as int, float, short etc. i would like to read an exactly four byte integer into an int, 2 byte short into a short etc. i need to read these parameters exactly of their specified number of bytes - not more or less - as if i read anything more/less, i will be reading a part of other parameter.
i know that C allows us to do this by letting us to specify number of bits we like to allocate for each data type (for eg. unsigned int:16; means i need an unsigned int of exactly 16bits (2 bytes long) -no more and no less).
Is there anything similar i can do in Java?
any suggestion is greately appreciated.
Thanks,

All primitive types in Java are well-defined. In contrast to C/C++, an int in Java is allways 32 bits, using one's complement, a char is allways 16 bits etc.
Java does not give you direct acces to physical memory - that would compromise the basic design of Java.
You can read individual bytes from files, and you can do all the integer arithmetic in Java as you can in C/C++. To convert eg. fout bytes to one int, you could do the following:
byte b1= (some byte value),
     b2,
     b3,
     b4;
