When I wrote the `VALUES` agg I didn't plug it in for `datetime` fields. Ooops. We just have to plug it in.

*Syntax*

[source,esql]

VALUES(expression)

|
|
|
|
`expression`::
|
|
Expression of any type except `geo_point`, `cartesian_point`, `geo_shape`, or `cartesian_shape`.
|
|
|
|
*Description*
|
|
|
|
Returns all values in a group as a multivalued field. The order of the returned values isn't guaranteed.
|
|
If you need the values returned in order use <<esql-mv_sort>>.
|
|
|
|
WARNING: This can use a significant amount of memory and ES|QL doesn't yet
|
|
grow aggregations beyond memory. So this aggregation will work until
|
|
it is used to collect more values than can fit into memory. Once it
|
|
collects too many values it will fail the query with
|
|
a <<circuit-breaker-errors, Circuit Breaker Error>>.
