In BOX R2 Universe how to create External Function in C++??

Hi All,
Can any one tell me how to create dynamic SQL Query in BOXI R2 Universe, I heard that we can create c++ custom external functions.
i know the procedure for using Oracle functions but that is taking more time to generate report.
I want to create a conditional statement inside universe
Following are three queries
Query1 = select a,b,c,d from aab where a=@Prompt(jjjjjjj)
Query2 = select a,b,c,d from aab where a=oracleFunction(@Prompt(jjjjjjj))
Query3 = select a,b,c,d from aab where a=@myFunc(@Prompt(jjjjjjj))
The above example is a simple one but in my real senario that function is called 120 times in my single query.
Query1 takes 7 minutes
Query2 takes 30-35 minutes (as that oracle function is called 120 times)
So i want to create a custom external function in c++ so that the conditional expression is evaluated at BOBJ Server and the result of that function goes as a normal static string to oracle server.
so it will again reduce the time
Any ideas..

Hi Mehmet,
Please provide following information:
1. How are you creating these functions (are you creating a Webi Extension Point)?
2. How are you compiling these functions?
3. Are you using Visual Studio to create these functions?
Webi Rich Client is a 32 bit application so a function which is compiled in 32 bit mode would be visible in it.
To access these functions through BI LaunchPad which is a 64bit application, we need to compile the function in x64 mode.
Also make sure you compile the function in Release mode.
Hope this helps.

Vinit Shete

Pls give some ideas? how to create a function.

Make an MS-Access form to accomplish:
Use a list box to display part-time employees and their assignments (SSN, Hours, FullName). Include only those who currently work a total of less than 40 hours/week.
SSN , Hours and FullName are stored in 2 different table.
I have no idea how to implement this function. How to create this function to get SSN, Hours and LastName and FirstName (RecordSet which will be used in application)?
Thanks alot!

I'm afraid this is an Oracle forum, not an MS-Access forum.

The file will keep inside server.AFAIK, you have to write a custom code to achieve this and Oracle does not provide this functionality.

How to create external view?

I want to create external view in master view or query view of master to detail group.
Could you healp me answer over and upload question, please.

Edwin,
I am sorry but I'm still not sure whether I understand your question. But the following might help you:
- you can create a database view in the database and then base a BC4J Entity Object and/or View Object on top of this view
- You can create a ViewObject where you type in the SQL yourself.
- You can create ViewLinks to create a master-detail relation between any two ViewObjects.
- You can
See the BC4J online help in JDev for more information. (For example the topic "About Polymorphic RowSets")
You also might want to read the following article on Steve Muench Weblog: http://radio.weblogs.com/0118231/stories/2003/02/06/constructingTheDesiredEntityInAPolymorphicViewObject.html

Creating external function

We are trying to create an external function that will be linked at run- time. How is such a function compiled?
Does it need to be compiled into a Dynamic library? Or would the function be called?
The operating system we are trying to do this is Sun UNIX Solaris. However any insight would be of great
assistance.

I have a nasty feeling there is in XQuery expressions, but I'm not going there. ;-)

How to call external functions without a .DLL (just using a .H and .LIB file)?

Hello everyone,
actually I'm facing little difficulties on how to get an external function getting called from within CVI (Version 2009).
I was supplied with a .H file and a .LIB file to call an external function from within my CVI project. The .H file looks like this:
void exportedFunction(double *parameter);
As far as I know, the external function was written with MS Visual C++ 6.
So I tried to statically link to the extern al function like this:
- Add the .H file and the .LIB file to the CVI project
- #include the .H file where I needed to call the external function
- do the external function call
When building I get an unresolved external function call error from CVI so this seems not to be working.
I made some searches around and got up with two possible issues. Maybe one of you can help me get a bit further and get things working.
1) The "real" function code is located in the DLL file which was not delivered to me. Or is there a way to get things done (call external functions) just with a .H and a .LIB file (without any .DLL file included)?
2) The external function does not export according to "C-Style" rules. The function signature in the .H file shows no things like
extern "C" __declspec(dllexport) void __stdcall ...
Or maybe it's a combination of both issues (missing .DLL + wrong export style of function)?
I guess I could get around the wrong export style of the function when I manage to write a wrapper around the original function that actually uses C-Style exporting. But I guess I need the .DLL file for this try as well.
Thank you for your answers.
Best regards,
Bernd
Solved!
Go to Solution.

There is no need for the dllexport stuff. There is also the option for a static library without any DLL. But the 'extern "C"' is essential, because it forces the C++ compiler, which was probably used to compile the library , to use C calling convention.
If you can't ask the provider of the library to provide a version which was compiled using C calling convention the way to go is to write a wrapper with VC++6 around that library which reexports the functions using C calling convertion. Something like
extern "C" type0 myfunc1(type1 arg1, ...) {
return func1( arg1,...);
for every function , you need to use.
BTW. "unresolved symbol" is the linker error message, you can expect if you try to link C code against a library build with C++ calling convention.
