Transformer code

Kirtikumar · Post by **Kirtikumar** » Mon Jul 18, 2005 7:33 am

Does anyone know about the C code location generated for transformer?
I tried to find the C code generated from transformer, but not able to locate the code. I got the executable generated for tramsformer, but not the C code.

why would you want the 'c' code?

Can anyone give any inputs whcih are the available functions which can be used in C routines

Hello,

Well first off, you need to make sure you compile your code with a C++ compiler and not a C compiler. Datastage calls your compiled code, (either setup as an Object/Library). Depending on which method you choose, Object is static and linked to the job (if you change your code you will have recompile the code and job), Library option is linked at run time and the object needs to be a shared library. You should be able to write standard C code, if you get it to work in Unix, Datastage is just going to execute the external code, therefore all the functions should be available for use in your code (of course you will have to include the correct libraries to use the certain functions).

Hi kirtikumar,
you can find the list of functions which can be used in your C code for you buildops in the documentation of the parallel extender like asString(),null(),isValid() etc ..
You check this example ,which can give some idea of how to use these functions in your code.

1 -->out.outputcolumnname = in.inputcolumnname.asInteger();

2 --->
if (!date.isValid()){
out.date_setnull();
}
else{
out.date = Date1;
}
}
