How to detect which data type is passed in ?

Hello!
I've built a VI function. But I want to make it more secure - that function could detect which data type is wired to the inputs and allow wiring only certain data types. How can I do this?
Thanks

I'm assuming you're talking about numeric datatypes. In this case that information is not available to you at the subVI level. The LabVIEW compiler will have already changed the datatype to match what your subVI expects if someone wires something of a different type.
You could use a variant as your input. Then in the subVI you can use the Variant to Flattened Data to get the type. The OpenG LabVIEW Data Tools VIs will be useful if returning an enum specifying the datatype. Specifically, using the "Get TDEnum From Data VI".
Now that we've gotten that out of the way, let's talk about the why. Why do you need to do this? What are you trying to "secure"?

How do I detect the data type of a node?

Hello all,
I have a few quick questions about using Schema with XDK. I hope someone can answer this for me.
1) How do I detect the datatype of a node? I need to be able to detect if it is date/time, number or boolean
2) How do I then parse the string into date, number, etc. ?
3) Does Oracle SOAP also support this kind of thing? (ie. detecting the data type of a node and then parsing it?)
4) Does XDK support inline schema?
thanks in advance!

Thanks for the response.
So are you saying that it is not possible or not easy to detect the typed value data type of a node? In past years, I have had experience with converting based on what looks like a number and it is impossible to safely assume something is a number just because it looks like one. For example a Product ID could be: 14E1 which many routines would detect as a scientific notation number. This is why I need to be able to detect the data type.
But I am no Schema expert, but my understanding of schema is that simple types have standard designations. I think it is something like xsd:string or xsd:number, etc. But no matter what parser I look at them all seem to be implemented the same way and I can't figure out with any of them how to detect the datatype and then parse it appropriately. But it should be possible since it is written into the schema.
Since I'm using Jdev I'm hoping that the Oracle XDK can do this, if not does anyone know of any good parsers that can? I'm having trouble even locating validating parsers. Aside from Oracles all I could find were IBMs and Xerces which both seem to be based on the same thing anyhow.
Help or pointers in the right direction would be much appreciated since I have been struggling with this seemingly simple task for a long time.

How to get the Data type of the Internal Table.

How can i get the data types used to create an internal table
TYPES : BEGIN OF t_makt,

How to add TIMESTAMP data type in Enterprise Architect...?

Hi all
There is no data type of timestamp in Enterprise Architech. There is only
DATE type. I have ERD prepared from Enterprise Architech. How to modify
DATE type to TIMESTAMP type.
How to add TIMESTAMP data type in Enterprise Architect or in ERD ?
Thanks in advance,
Pal

Have you asked this question of the vendor of Enterprise Architect? They may have a later version that supports the various TIMESTAMP data types. If your ERD tool doesn't support a data type, other than talking to the vendor or working around the problem (i.e. generate DDL to a text file and edit it before applying it to the database), you're probably out of luck.

How to use same Data Type and Length for two fields

How to use same data type and length for two fields when using 'FOR ALL ENTRIES IN' in a select statement? For instance the select queries are :
SELECT bukrs gjahr belnr lifnr budat bldat zlspr dmbtr waers shkzg
FROM bsik
INTO TABLE it_bsik
WHERE bukrs = p_bukrs
AND lifnr IN s_lifnr.
IF it_bsik IS NOT INITIAL.
SELECT belnr gjahr awkey awtyp
FROM bkpf
INTO TABLE it_bkpf
FOR ALL ENTRIES IN it_bsik
WHERE belnr = it_bsik-belnr
AND gjahr = it_bsik-gjahr.
IF it_bkpf IS NOT INITIAL.
SELECT belnr gjahr lifnr xblnr
FROM rbkp
INTO TABLE it_rbkp
FOR ALL ENTRIES IN it_bkpf
WHERE belnr = it_bkpf-awkey+0(10)
AND gjahr = it_bkpf-awkey+10(4).
ENDIF.
ENDIF.
Here it gives an error in the 3rd select query that 'When you use the addition "FOR ALL ENTRIES IN itab", the fields "GJAHR" and "IT_BKPF2-AWKEY+10(4)" must have the same type and the same length.'
Kindly clarify.

Hi Saurabh,
Please see the example code that I have developed for you. It will help you solve the problem.

append it_bkpf1.
clear it_bkpf1.
endloop.

This is just an example. Change the fields according to your requirement.

Which data types I have to use.

hi all,
I was using DEC '9' for a variable.
ie., tunni type DEC of length 9. For smaller values like 000000488225584 is ok.
But for larger values like 000001048988458000000513871057 is going to dump.
Please suggest me which data type I have to use.
It should not be effect the performance.
Thanks in advance.

Hi,
Try use numerical character (TYPE N).

Which Data-Types can be used as Widget Parameters?

Hi,
I have been playing about with widgets (specifically widget parameters) for a while now.
I've got to wondering, exactly which data-types can Captivate turn into widget parameters?
So far I know that you can use:
Numbers,
Strings,
Arrays,
Objects
and Booleans,
as parameters.
Which ones am I missing?
I know some don't work, because I tried storing a MovieClip as a parameter and that didn't work.

Hi Eccles,
You can set all basic data types supported in flash viz.,
1)Numbers
2)Strings
3)Arrays
4)Objects
Since in Action script , an Object can be anything (array , array of objects , array of objects which by themselves are array of objects and so on ) , you can virtualy send anything as widget params
But there are two caveats to this
1)Object References
-Object References do not have any meaning once the swf is closed.But the widget params have to be stored across sessions.So If you send a reference as part of widget params it is not going to work.
This is why sending a Movie Clip (which is actually a reference to an Object ) does not work
If you want to send such things you will have to 'serialize' the object.
2)Size of the Object that you send
The size of the object that you send can have an impact on performance.And since any object that you send has to be converted into XML , objects like bitmaps can turn out to be huge and difficult to handle.
This brings us down to this - you can send any object across as widget param as long as it is small and serialized.

How to change the data type in the table ESLL for the field USERF2_NUM ?

Hello Friends,
I have a requirement in which one of the change is to convert the data type of the field 'USERF2_NUM' in the table 'ESLL' from 'QUAN' to 'CHAR'.
How do i do it if i have an access to change it..........i think i should also check the impact of the change if done.
Kindly tell me as my requirement starts with this small change.
Regards,
Rajesh Kumar

Thanks for the reply Sowmya.
I would like to know 2 things.
1. Is it ok to change the data type of the field 'USERF2_NUM ' which is in the table ESLL. from quan to char.
2. The table ESLL already has entries. if we change the data type from QUAN to CHAR what is the effect on the existing entries of the table .
Kindly reply me back.
Thanks & Regards,
Rajesh Kumar

How to Find the Data Type of the Field In a Database Table

Hi Experts,
I'm currently working on a program which needs to find out the data type of the given field in a database table. In addition to accessing DD03L directly, is there any other workaround such as function module to help me achieve this? It would be helpful if a demo example could be provided.
Thanks a lot.

Hi,
Use this..
DESCRIBE FIELD dobj TYPE typ.
write typ.
type will contain the data type of the object.

How to know which stock type updated within movement type

Expert,
I need to know which stock type updated within each movement type.
I'm using two different system (SAP and Oracle) which is in each system updating stock. So i need to do stock calculation manually from that two systems.
I'm planning to imported material document data (from MKPF & MSEG) to Oracle and then combine the stock calculation.
And then i'm facing this :
Ilustration :
MIGO transaction - Goods Receipt PO - Stock Type Unrest
in MSEG field BWART : 101, SHKZG : S, INSMK : blank --> no problem
MIGO transaction - Goods Receipt PO - change Stock Type to Quality Inspection
in MSEG field BWART : 101, SHKZG : S, INSMK : 2 --> no problem
MIGO transaction - Transfer Posting - movement type 322 (reversal QI to Unrest.)
in MSEG field BWART : 322, SHKZG : S, INSMK : blank --> problem
in MSEG field BWART : 322, SHKZG : H, INSMK : blank --> problem
I have a problem that in MKPF & MSEG there is no indicator which stock type updated within movement type (BWART) 322.
How to know that first row will be updating stock QI and second row will be updating stock Unrest.??
I've already checked to OMJJ, SM30-V_156SC_VC, table T156... and still having no clue.
Or is it just a 'hardcode' ? And i need to do 'hardcode' too in Oracle system?
Thank you so much.

The stock type indicator doesn't update for the movement type 322 in table MSEG.
At the time of transferring, you do not have to enter the stock type for movement type 322.
I can give you one clue, check can it fulfill your requirement.
You have two line items for movement type 322 in MSEG table, There are a field XAUTO will be updated as X for credit entry.
You can assume, the line item (without value for XAUTO) is for less from QI stock and the line item (with value X for XAUTO) is for add to unrestricted stock.

How to access complex data type from a soap web services?

can u please tell me how can i access complex data type from a soap web service from jdeveloper 10g
Jdeveloper generates 3 classes

i have to retreview the data which is a complex data type it gives some
unknown type. and the return value is a key-value pair data type .

After you create the partner link and the invoke (to create the variables), change the element type of the response message to the complex type definition of your collection that appears in the XSD. You can do the same thing if you want to change the element type of the payload of the request message as well.

I need help in "HOW TO EXTEND THE DATA TYPE SYSTEM"......

Hi All,
I need to add new data type like SDO_GEOMETRY in spatial Oracle.
I don't mean the User-Defined Datatype but new datatype embed in the database.
I read the Data Cartridge Developer's Guide but it has info how to use more efficiently UDT through indexes.
Anybody used the “Type System” under Databases and Extensibility Services?
It might be written in C++ or Java but I do not know how.
Any hints and help will be appreciated.
Thanks,

> In Figure 1-1 Oracle Services, there is a "Type System" as Oracle Services.
The "Type System" is merely a compartmentalising the data type handling and implementation code/modules in Oracle.
This covers all types. Oracle native types, user defined types (UDTs), etc.
Saying that you want to create a new type in the "Type System" is basically saying you want to use the CREATE TYPE SQL command in Oracle.
> So, I want new_type1 and new_type2 behave like other built-in types, just the way
SDO_GEOMETRY works in Oracle Spatial Cartridge.
Not familiar with the SDO_GEOMETRY. Why do you mention this type specifically? What do you want to do similar?
> I have already done it with user-defined types. Now I need to do this way so that I can
compare and contrast in terms of speed, space...etc for part of my research.
Hmm.. I'm not sure what you are trying to compare ito of a UDT and Data Cartridge extensions. It is not one or the other. What research is this if I may ask?
Simplistically you extend the Type System with a new UDT/ADT. And there you have a new type data can be used in the SQL Engine and the PL/SQL engine. The OCI (Oracle Call Interface) supports such types via the OCI object API calls - which means this new type can also be used from Oracle clients written in Delphi, C++, Java, etc.
That new type can be a complex type. This type may need specific management code (memory management, context management, internationalisation, etc). To support this you can extend the UDT/ADT further by developing Cartridge Basic Service interfaces for the type - designing and writing management code to, for example, support specific internationalisation requirements when dealing with multibyte character sets.
You can also extend the UDT/ADT to be custom managed ito indexing, determining query optimisation, computing costs of custom methods/functions/operators on this custom data type. These extensions are done by developing Data Cartridge interfaces for the type.
Thus I cannot see what you are trying to compare. It is not one layer/interface versus another. These layers exist for all Oracle types (in the Type System). Oracle not only allows you to add to the top layer by adding/defining a new data type. It also allows you to customise (if needed) the layers below it.

How can I implement it.
I know proc can implement it, simply set selda->T[sli] with 1 for any field.

Hello,
What's your LabVIEW version ? Do you have a simple example program which demonstrates this behavior ?
I found another discussions related to your issues with Xcontrols:
