Transformer Stage Functions

[DSguru2B]

Did you make this particular column with that humongous derivation a nullable column? Another point, nulls arent really populated in a flat file. You will just see an empty value.

Nulls are populated in a flat file with whatever you specify as the Null Field Value property.

Thanks a ton Ray!

I plugged in your code and concatenated with "V-" and it works great except for 5 & 6. (Values after ----------------> are the results)

Code: Select all

1. "3.5 L V6 24-Valve DOHC"  --------------------->  V-6   
2. "3.8 L V-6 24-Valve DOHC" --------------------->  V-6
3. "4.6 L V8 w/4 valve per CYL" ------------------->  V-8
4. "5.5 L 32-Valve Aluminum V-12"---------------->  V-12
5. "5.9 L V-12 32-Valve Aluminum"---------------->  V-
6. "3.9 L V6 32-Valve Aluminum"------------------>   V-
7. "AMG 5,439-cc 24-Valve Supercharged"------->  Null

How do you account for when the data is similar to 5 & 6 (When V6 or V-12 comes in before the word "Valve")

Any suugestions?

TIA

Try replacing the constant in the pattern ("V") with " V".

Code: Select all

If InLink.Product Matches "0X' V'1N0N0X" Then MatchField(InLink.Product, "0X' V'0N0X", 3) Else If InLink.Product Matches "0X' V-'1N0N0X" Then MatchField(InLink.Product, "0X' V-'0N0X", 3) Else @NULL

Hey folks

My team lead has decided not to go with BASIC Tfr as he needs this to be a pristine DS-EE environment.

Looks like I need to develop a C-routine for this purpose.

Any suggestions, samples, pointers on developing a C-routine.

TIA

[DSguru2B]

Use strstr() C funtion to locate your string and then do substrings or you can use sscanf() to get the literal you require.

[DSguru2B]

Give it your best shot, post your code here and then we can go from there. Its not that hard.

My team lead has decided not to go with BASIC Tfr as he needs this to be a pristine DS-EE environment.

Thinking of a word that rhymes with "anchor" but isn't "banker".

The DS-EE environment includes the BASIC Transformer stage. Therefore including such a stage does not in any way detract from your environment being pristine.

What we have with the BASIC Transformer stage is a tool that can do the job and which is part of the toolset. Now there's a requirement to develop in a language with which no-one on the team is familiar. What's wrong with this picture?

Hello folks

I was wondering if there is C-routine sample that somebody could pass across. I searched for it but could'nt find what I need.

It would be of great help to me as I will learn to code in a new language.

TIA

Well, its kind of hard to teach you a new language just through description. You have to go through language syntax, create your first program "Hello World", go through some functions etc etc etc.
Ill give you a piece of code, you can go through it, google up the functions, see what they do.

Code: Select all

//header files
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

//Main Function
char* GetEngineInfo(char* inp)
{ //Declare Variables
  const int SIZE = 100;
  char* out = (char *)malloc (SIZE);
  char* x = (char *)malloc (SIZE);
  char* p = (char *)malloc (SIZE);
  int i = 0;

  //Check if input is empty
  if (strlen(inp) < 1)
    return NULL;

  //Strip out the literal "Valve"
  x = strstr(inp, "Valve");
  if(x)
    strncpy(x, "     ",5);

  //Look for character "V". If not found then search for "V-"
  p = strstr(inp, "V");
  if(!p)
    p = strstr(inp, "V-");

  //If either "V" or "V-" are found get everything untill you hit space
  if(p)
  {
    while(strncmp(p, " ", 1) != 0 )
    {
     out[i++]=*p++;
    }
      out[i] = '\0'; //terminate string
  }
  //Return NULL if not found
  else
  {
    strcpy(out,NULL);
  }

 return out;
}

The description for each and every function used in the code above can be googled up. C has been around for ages and hence a lot of information present on the web.

Thanks a bunch DSguru2B. Appreciate all your help. I will try and let know.

Thanks once again

Hi,
Is there any documents available for C-Guide( by IBM) like Basic Guide is available under "Ascential\DataStage751\Client\Docs"

Thanks

[DSguru2B]

Not that I know off. One of the primary reason being that C is widely used and has been around for many years and hence a lot of reference material can be found online.
