Use Expression Transformation after Source A Qualifier to perform calculation after that you can join through Joiner Transformation.

You can use an Expression transformation to calculate the value required. This would be placed between Source A and the joiner, with an output only port added with the logic inside.

However, if the calculation is simple enough, you can have it pre-computed in the SQL query for Source A. This is advantageous as it will allow you to sort both sources on the common column(s) and use the Sorted Input option on the Joiner, which performs much better.

informatica-powercenter Mapping variable in Java

How do I access a mapping parameter ($$myvariable) from a Java Transformation in Informatica Powercenter?

What I want to do is to make a Java transformation reusable by making a part of it configurable, and a variable seemed suitable for that, however I haven't been able to access (read) a variable from the Java code.

How to add variable inside an embedding gravity forms in Wordpress?

I need to add a variable inside an array of an embedding gravity forms to populate 2 hidden fields: email and jobname.

Here is my code:

<?php 

    $email = get_field( "email_application" );
    $jobtitle = get_the_title();

    gravity_form( 5, false, false, false, array('email'=>'echo "$email";','jobname'=>'print "$jobtitle";'), false); 
?>

I know that echo, print or just the variable doesn't work as it show like this in my code:

<input name="input_6" id="input_5_6" type="hidden" value="print $jobtitle" class="gform_hidden" aria-invalid="false">

and

<input name="input_5" id="input_5_5" type="hidden" value="echo "$email";" class="gform_hidden" aria-invalid="false">

Instead I should get:

<input name="input_6" id="input_5_6" type="hidden" value="My job title" class="gform_hidden" aria-invalid="false">

and

<input name="input_5" id="input_5_5" type="hidden" value="myaddress@email.com" class="gform_hidden" aria-invalid="false">

Can someone could point me in the right direction.

Thank you.
