"Applying new values based on filter"

clarkem1

Hi Chaps,

I'm sure this is qa very simple thing but I cannot seem to find an operator which will let me do it. I essentially want to apply a filter on some data then allocate it to a particular group in a column, I.E IF Column C contains this then Column D belongs in group 1.

So simple I know but I would really appreciate some help. I have watched the tutorial videos and whilst they were useful didn't really answer my questions.

Hi,

you are looking for the "Generate Attributes" operator.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="6.6.000-SNAPSHOT">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="6.6.000-SNAPSHOT" expanded="true" name="Process">
    <process expanded="true">
      <operator activated="true" class="retrieve" compatibility="6.6.000-SNAPSHOT" expanded="true" height="68" name="Retrieve Deals" width="90" x="45" y="34">
        <parameter key="repository_entry" value="//Samples/data/Deals"/>
      </operator>
      <operator activated="true" class="generate_attributes" compatibility="6.6.000-SNAPSHOT" expanded="true" height="82" name="Generate Attributes" width="90" x="179" y="34">
        <list key="function_descriptions">
          <parameter key="Rating" value="if(matches([Payment Method], &quot;.*cheque.*&quot;), &quot;bad&quot;, &quot;good&quot;)"/>
        </list>
      </operator>
      <connect from_op="Retrieve Deals" from_port="output" to_op="Generate Attributes" to_port="example set input"/>
      <connect from_op="Generate Attributes" from_port="example set output" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>
