I want to include in that table all the tags related to the same contact, but when several tags are set, the record of this contact is repeated in the list for each tag.
I wonder if it is possible, using
data-processor, to include one column of my table grouping all the occurences of the tag field with the concatenation function, as with the MySQL function
CONCAT_WS (separator, expression1, expression2, expression3,...). The separator should be the string
, (comma blank).
