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

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".

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.

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

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:

Question about uesr-defined data types

Can anyone help me to answer the question?
Explain the user-defined data types in Oracle Spatial, and give examples how these data types and their associated operations are used to support
i.     Storage
ii.     Indexing
iii.     Retrieval
of spatial data.
thanks!!

you need to look at the oracle spatial user's guide, which gives most of that information. it is downloadable from otn...

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.

Any idea what this errorr means? the data type of the reference does not match the data type of the variable

I am using Veristand 2014, Scan Engine and EtherCat Custom Device. I have not had this error before, but I was trying to deploy my System Definition File (run) to the Target (cRio 9024 with 6 modules) and it failed. It wouldn't even try to communicate with the target. I get the 'connection refused' error.
I created a new Veristand project
I added the Scan Engine and EtherCat custom device.
I changed the IP address and auto-detected my modules
i noticed tat Veristand didn't find one of my modules that was there earlier. (this week)
So, i went to NiMax to make sure software was installed and even reinstalled Scan Engine and Veristand just to make sure.
Now, it finds the module, but when i go to deploy it getsto the last step of deploying the code to the target, and then it fails.
Any thoughts?

Can you deploy if you only have the two 9401 modules in the chassis (no other modules) and in the sysdef? I meant to ask if you could attach your system definition file to the forum post so we can see it as well (sorry for the confusion).
Are you using any of the specialty configurations for the 9401 modules? (ex: counter, PWM, quadrature, etc)
You will probably want to post this on the support page for the Scan Engine/EtherCAT Custom Device: https://decibel.ni.com/content/thread/8671
Custom devices aren't officially supported by NI, so technical questions and issues are handled on the above page.

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.

JDBC MS Access--- cannot extract entry with null value with data type Meta

I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
Any advice will be appreciated! thanks!
Following are the table description and JDBC code:
test table has the following attributes:
Field name Data Type
name Text
label Memo
table contents:
name label
me null
you gates
Code:
String query = "SELECT name, label FROM test where name like 'me' ";
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
String name = rs.getString("name");
rs.getString("val");
String label = rs.getString("label");
System.out.println("\t"+name+"\t"+label);
catch (SQLException ex)
System.out.println(ex.getSQLState());
System.out.println(ex.getErrorCode());
System.out.println("in sqlexception");
output:
C:\Temp\SEFormExtractor>java DBTest
yet SELECT name, label FROM test
null
0
in sqlexception

The question is how to extract null entry with data type memo?Okay, what you need to do is this:
if (rs.getString("val") == null)
// do something
}This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception.

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object
reward if useful

Performance and data types: which to use?

Hi All,
I am wondering what data type to use and the effect of them on memory/speed.
1. What is the difference (if any) of using sgl, dbl, int etc. Looking at the LabVIEW help there seems to be a range of 8-256 bits of storage according to the data type. Is it basically choose the one with the smallest storage that can fit the data?
2. I currently have a cluster flowing through subVI's. The cluster contains the start time (or freq), the delta t (or f) and the array of data (about 500-5000 elements). I tried to use the waveform datatype but it couldn't handle a delta t of 2 nanoseconds (500 MHz signal). Am i ok using the cluster, or should i seperate the components and pass them along? What data type should i use for each of the components?
Thanks

There are three main issue to consider.
Range and accuracy. If you need a very high level of accuracy, then you will need to use the extended data type or even create your own, although that's unlikely.
Memory. Yes, SGL takes less than DBL, but unless you're dealing with really huge amounts of data this won't matter.
Coercion. Most built in functions work on DBL. If you wire a SGL into them, they will coerce it, possibly creating a copy of the data and increasing your memory usage.
To sum it up, most of the times it would be best to use the default DBL. It's highly unlikely you'll need one of the others.
As for your second question, it sounds to me like the data is a single organism, so I would say you should leave it in the cluster, but that really depends on whether the functions need it or not and whether you're constantly bundling and unbundling the cluster. Note that 5000 elements is far from being a large array and you shouldn't have any problems handling it.
As for the timing unit, if you really only have 5000 elements (that's 10 microseconds of data?) then you should not have a problem with using a U32 with a nanosecond as the base unit. That should give you the ability to measure more than 4 seconds.

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.

to our DBA, he said all of the calculations in the cube are double precision floating point and I need to round all results to 2 decimal places (programs like Excel handle the rounding and I should too.)
Our DBA also claims the measures can't be calculated and returned as currency. He claims that the potential for error is very small and no one has ever complained about a $ value being off.
I am struggling with this answer because I have always been told never to use floating point for monetary values. I am having a hard time believing there is no way to have a measure be a currency field that is accurate. I looked for articles
online but can't seem to find anything to answer my questions.
Could someone please point me in the right direction? Thanks so much!

Your DBA is not completely correct in his claims. All calculations are not floating point below is a link to all of the data types supported by SSAS (Multi-Dimensional)

SSAS supports a currency data type. It's 4 decimal places not 2, but it is the recommended data type for currency values as it does not suffer from the imprecision of the double data type.
The other thing measures in a cube have is the concept of a format string, so you can ask the cube to return a pre-formatted value to you. But default an OPENQUERY will just return the raw value, but if you add the following:
CELL PROPERTIES FORMATTED_VALUE
to the end of your MDX query that should tell it to return the formatted value (which could be something like "$#,##0.00")
