Get rows from result step and Get Varaibles usage in Pentaho data Integeration

Question

can any one provide example for both get variables and get rows from result step in pentaho data integration.

1. I have a job with two transformations.
2. First transformation take sample input and genrate sample output and a the end i have copy rows to result step.
3. My 2nd transformation has get rows from result step and a dummy.
4. When I run my job i am not gettion output in the dummy.
5. I even tried with the Get Variables Step instead of Get rows from result step even though i am not getting the output.
6. so,how can i solve this.

Answer 1

So, to make the answer as graphic and abstract as possible, let's assume we have a main job, and two transformations inside it (they could also be two sub-jobs).

Job:

Read Process Parameters would end like this:

Do something nice would have the following settings:

Under Advanced tab, 'Copy previous results to parameters?' check-box would be checked; If you wished the transformation to execute for each row, you would check the 'Execute for every input row?' check-box ;

Answer 2

maybe you should uncheck "copy previous result to parameter", this make the result(output by the previous trans) disapear ( anyway ,can't be get by "get rows from result" )
