Table Variable Lookup

It would be great if I could perform a lookup against a Nintex Data table variable without having to run a query every time.


For example, let's say I query my table for records meeting some criteria. The ONLY way for me to obtain a value from that data lookup is to loop through it. So, you can find yourself looping through that Data Lookup just to find the data you need, then exit.

What I would love is a way to do a lookup.

  1. Pull Table into Workflow using the existing Query Action

  2. Perform some Lookup - Retrieve value from a specified column, by searching a specified column

This would work the same way as a List Lookup in RPA LE/Foxtrot.

    For more information, here is how I was able to get around this limitation:

    1. Run a RegEx on the 'Rows' from a table

    Operation = Replace
    Pattern = (?<=\[|,)"(?=\{)|(?<=\})"(?=,|\])|\\(?=")
    Replacement Text = an empty variable
    Store first result = rowJSON variable

    2. Query JSON
    JSON Source= rowsJSON variable
    JSONPath = $[?(@.apiNameOfTheFieldSearching == 'valueToSearch')].apiFieldNameToReturn
