=== `EVAL`
|
|
`EVAL` enables you to append new columns:
|
|
|
|
[source.merge.styled,esql]
|
|
----
|
|
include::{esql-specs}/docs.csv-spec[tag=eval]
|
|
----
|
|
[%header.monospaced.styled,format=dsv,separator=|]
|
|
|===
|
|
include::{esql-specs}/docs.csv-spec[tag=eval-result]
|
|
|===
|
|
|
|
If the specified column already exists, the existing column will be dropped, and
|
|
the new column will be appended to the table:
|
|
|
|
[source.merge.styled,esql]
|
|
----
|
|
include::{esql-specs}/docs.csv-spec[tag=evalReplace]
|
|
----
|
|
[%header.monospaced.styled,format=dsv,separator=|]
|
|
|===
|
|
include::{esql-specs}/docs.csv-spec[tag=evalReplace-result]
|
|
