How to execute a packaged function from within DML

Hi
can someone explain in how many ways can we execute a packaged function from within a DML statement.
examples will help.
Thanks

Hi,
There's no difference between using functions in DML and using functions in any other SQL statement. Almost any place where a literal is allowed, you can have any kind of expression, including a an expression involving one or more functions.
For example, in
UPDATE table_x
SET column_a = 0
WHERE column_b > SYSDATE;You could use functions instead of 0, column_b, or SYSDATE. (Actually, SYSDATE is a function.) You can not use functions instead of table_x or column_a (since it is to the left of the "=" sign).

How to execute a Perl program from within a Java prog

How do I execute a Perl program from within a Java program.
Lets say the Perl program that I want to execute is 'abc'. Now, 'abc' requires some input that I want to give it from within the Java program. How do I do it?
And finally, how do I execute that Perl program from within the Java program.
If I execute the Perl program alone then I do it in the following way -
perl abc inp1 inp2 inp3
where inp1, inp2, inp3 are inputs to the Perl program. I will not be able to change or modify the coding of the Perl program - 'abc' as I do not have access to its code. Its a kind of an application whose usual method of execution is in the above shown way. So, how do I execute 'abc' from within a Java program.

what part of don't crosspost, don't you understand?

How to write custom messages to Data Manager package log from within SSIS?

Just wonder in BPC 7.0/7.5 MS how do you write custom messages to Data Manager package log from within SSIS? I mean I want to log output of specific custom tasks (non-BPC) in SSIS control flow to the resultant BPC package log created when running SSIS package in Data Manager. Can this be done in a Script Task or some other way? Not much documentation out there on this.
Thanks,
Brian

Hi Brian
In order to achieve what you want, it can get tricky in your package, ultimately It would depend on the task, for example if you had an execute SQL task, you could use a RAISEERROR command in your SQL statement and BPC would return the error message that you specified.
If you had other tasks, then it would be a bit more tricky, you would have to have custom messages based on event handlers.
Please see below links for examples :
[Custom messages for logging|http://msdn.microsoft.com/en-us/library/ms345174.aspx]
[Custom Logging Using Event Handlers |http://consultingblogs.emc.com/jamiethomson/archive/2005/06/11/SSIS_3A00_-Custom-Logging-Using-Event-Handlers.aspx]
Hope this helps
Kind Regards

Possibility to execute Acrobat Pro's "Combine files into PDF" function from within SAP?

Good day.
Presently, a company uses Acrobat Pro to manually combine files such as *.pdf, *.jpg, *.doc, which have been downloaded from SAP's Document Management System, into one pdf file. I would like to know if it is possible to automatically execute Acrobat Pro's "Combine files into PDF" function from within SAP (ECC 6.0) application system. I'm wondering if this could be achieved from a program via OLE (Object Linking and Embedding) or RFC (remote function call).
Thanks in advance for your thoughts and inputs.

Yes, you can combine PDF files via IAC/COM methods.

How do i call a Function from another Function ?

When i press a button, i want a series of functions to execute one after another (they contain tweens, but its irrelevant), each of them waiting for the previous to be completed. I want to put the series of functions inside one function, so i can call just this function to execute all the others. The animations are working fine, but i dont know how call Functions from within another function. Also it would be necessary each function to wait until the previous has completed, to execute. Here is a clear example of what i need to do:
boton.onPress = animate ;
Function animate () {
     animation1 (onComplete: animation2);
     animation2 (onComplete: animation3);
     animation3 ;
Function animation1 () { Tween 1};
Function animation2 () { Tween 2};
Function animation3 () { Tween 3};
any suggestions ?

I'd do something like this:
boton.onPress = animation1 ;
Function animation1 () {
     var Tween1 = new Tween();
    Tween1.onComplete = animation2;
Function animation2 () {
     var Tween2 = new Tween();
     Tween2.onComplete = animation3;
Function animation3 () {
     var Tween3 = new Tween();

Using 'export -f FUNCTION' from within a script doesn't work

Why doesn't the 'export -f FUNCTION' work as expected in the following:
#!/bin/bash
target="$1"
[[ -z "$target" ]] && echo "No target specified." && exit 1
work() {
bsdtar -xOf "$target" .PKGINFO | egrep -w 'pkgname|arch|pkgdesc|group|conflict|depend|replaces' | sed -e 's/pkgname/\npkgname/' >> /scratch/pkgs.log
export -f work
find /scratch/repo -name "$target*.pkg.tar.xz" | parallel work
It errors out when called:

Yay for ineffective crossposting... https://bbs.archlinux.org/viewtopic.php?id=153461
Exporting functions is recommended in the parallel man page.
The command must be an executable, a script, a composed command, or a function. If it is a function you need to export -f the function first. An alias will, however, not work (see why http://www.perlmonks.org/index.pl?node_id=484296).
Also, how is this a cross post? The post you referenced is about parsing input, this one is about calling a function from within the parent script.

How to Execute SSIS package through MySQL Procedure

Hi Everyone,
How to Execute SSIS package from MySQL Stored Procedure.
Please share your suggestions on this.
Regards,
Vaishu

I am not sure whether you have SSIS license version installed in the system where MYSQL is there. In order to run SSIS package we need to have DTEXEC executable file and it comes with SSIS license version.
An SSIS package can be executed from command prompt as,
C:\>dtexec /f E:\package.dtsx
I am not expert in MYSQL however in TSQL we can run dos command or scripting language such as vbscript.
Similarly you need to check in MYSQL. This is MSSQL Server forum.

thank you in advance.

There are two ways to call a function from within an ItemRenderer. One way is to dispatch an event from your ItemRenderer and listen for the event in your main application. This approach has the advantage of creating loosely coupled code which is eaiser to maintain and extend if needed, but it takes a bit more work to set things up than using the second aproach lised below. You could also create a custom event to have greater control over what data is sent with the event.
private function callOuter():void {
     this.dispatchEvent(new MouseEvent());
The other approach is to call the main application by using parentDocument.
private function callOuter():void {
     parentDocument.handleItemRenderer();

How to call a SQL function from an XSL expression

In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :
