Table Transformer - Select Through Multiple Items Within Key Cell - Unable to Join Tables

Emily Berg_alwhtk

Good morning community!

I am trying to join two tables together, but my 'key' contains multiple items within a given cell. Is there a way to index through each item within the cell to check for a match / join?

In the top table key SR-3679 is "tested by" three different "TER" links. The bottom table provides the details for the individual "TER" issues. I need to be able to either:

Create a table with 3 separate rows for SR-3679 showing the details of each "tested by" TER OR
Create a table and merge the details of all TER within the single SR-3679 row

Any suggestions, please!

Hi @Emily Berg ,

We've recreated your case here:

If you have the only one type of keys (TER-XX), then we suggest using the following SQL query (it will be a more reliable one):

SELECT * FROM T1
LEFT JOIN T2 ON T1.'Tested by'->split("TER-")->indexOf(REPLACE(T2.'TER Key', "TER-", "")) > -1

Thu 6-2.png Thu 6-3.png If you have other types of projects (keys), then you may use a simpler query:

SELECT * FROM T1
LEFT JOIN T2 ON T1.'Tested by'->indexOf(T2.'TER Key') > -1

Hope this helps your case.

Are these tables a result of JIRA filters?

Anyway, if I understood your question right, then this might help:

You already have the table for SR issues (let this be T1)

Filter and create a separate table for all TER issues affected in your SR table(let this be T2), then with these 2 tables in the same table transformer macro:

SELECT
(SELECT T1.'Key' FROM T1 WHERE T2.'TER Key' IN T1.'Tested By') AS 'SR Key',
T2.'TER Key',
T2.'TER Summary',
...
any other columns
...
FROM T2

This way you will have something like this:

@Kántor Tibor - Thanks for the response. This works only for the first row of T1 data. I need to be able to loop this function through a large T1 with multiple rows. Is there a way to incorporate a while loop or something similar to index through the entire T1 table?

Not sure why... I have the same setup, separating linked issues to different rows, and it loops through the whole T1 table. Might not be a while loop issue?

@Katerina Kovriga _Stiltsoft_ ,

This is AWESOME! Thank you very much for the response! Could you elaborate on why the first solution would be more reliable (for my own edification)?

The first variant splits and then joins your keys strictly - as you can see, there is the name of your project "TER-" included into the 'split' and 'indexOf' sql functions.

If you work with another project, then you'll have other keys (for example, WER-13, WER-15, etc.) and put "WER-" for 'split' and 'indexOf' functions.

The second variant is a more general and simple one. It works, but the result table should be checked manually at first if you have multiple project names with similar key indexes to prevent any mismatching.

Thank you @Katerina Kovriga _Stiltsoft_ ,

As you pointed out, the general approach is less robust and I am now seeing an issue because of similarities with other keys.

I have another problem regarding this request - my key field is not just "TER-", rather its a custom field that contains other text, e.g. "TER-XXX | Status | Summary". How would I break out just the key from this field in order to proceed with the split function mentioned above?
