*Examples*
|
|
|
|
[source.merge.styled,esql]
|
|
----
|
|
include::{esql-specs}/date.csv-spec[tag=to_datetime-str]
|
|
----
|
|
[%header.monospaced.styled,format=dsv,separator=|]
|
|
|===
|
|
include::{esql-specs}/date.csv-spec[tag=to_datetime-str-result]
|
|
|===
|
|
|
|
Note that in this example, the last value in the source multi-valued field has not been converted.
|
|
The reason being that if the date format is not respected, the conversion will result in a *null* value.
|
|
When this happens a _Warning_ header is added to the response.
|
|
The header will provide information on the source of the failure:
|
|
|
|
`"Line 1:112: evaluation of [TO_DATETIME(string)] failed, treating result as null. "Only first 20 failures recorded."`
|
|
|
|
A following header will contain the failure reason and the offending value:
|
|
|
|
`"java.lang.IllegalArgumentException: failed to parse date field [1964-06-02 00:00:00]
|
|
with format [yyyy-MM-dd'T'HH:mm:ss.SSS'Z']"`
|
|
|
|
|
|
If the input parameter is of a numeric type,
|
|
its value will be interpreted as milliseconds since the {wikipedia}/Unix_time[Unix epoch]. For example:
|
|
[source.merge.styled,esql]
|
|
----
|
|
include::{esql-specs}/date.csv-spec[tag=to_datetime-int]
|
|
----
|
|
[%header.monospaced.styled,format=dsv,separator=|]
