MV_CONCATedit
Converts a multivalued string field into a single valued field containing the concatenation of all values separated by a delimiter:
ROW a=["foo", "zoo", "bar"] | EVAL j = MV_CONCAT(a, ", ")
| a:keyword | j:keyword |
|---|---|
["foo", "zoo", "bar"] |
"foo, zoo, bar" |
If you want to concat non-string fields call TO_STRING on them first:
ROW a=[10, 9, 8] | EVAL j = MV_CONCAT(TO_STRING(a), ", ")
| a:integer | j:keyword |
|---|---|
[10, 9, 8] |
"10, 9, 8" |
