Table Transformer - concatenate data from multiple rows based on criteria


SQL functions in Table Transformer is limited that i'm having trouble concatenating/merging data from multiple rows.



Project  | Remarks

P1   |  The quick brown

P1   |  Fox jumps

P2   |  Over the

P2   |  Lazy dog


I need it to produce the output below:

Project | Remarks

P1   | The quick brown Fox jumps

Hi @Joel Tabares ,

It seems that's a duplicate question for this one.

Let me repeat the answer here:

There are two options to resolve your case: the Table Transformer macro and the Pivot Table macro.


Option 1. Table Transformer

Use the following custom SQL query: SELECT T1.'Project', SUM(T1.'Remarks' + " ") AS 'Remarks' FROM T1 GROUP BY T1.'Project'


Option 2. Pivot Table

Recreate the settings from the screenshots below:

Hi Joel,


if you could add an ID to your source table, like this


ID | Project | Remarks

1   | P1   |  The quick brown

2   | P1   |  Fox jumps

3   | P2   |  Over the

4   | P2   |  Lazy dog

It works with this sql.

SELECT concat (a.'Remarks'," ", b.'Remarks') FROM T1 a, T1 b where a.'Project'=b.'Project' and a.'ID'<b.'ID'


Usually I would use the rownum instead of the ID in SQL, but that didn't work for me in the table transformer.

Hi @Bastian Stehmann ,

ROWNUM() function returns the current row number. You can try to use it instead of the ID column.

Ah, great, thank you very much.

Thank you all. Yes it was a duplicate question. I accidentally created the first one under the product Jira and couldn't delete it so i created the same question under Confluence.  I have what i need now. Thanks again!
