=== `RENAME`
|
|
|
|
Use `RENAME` to rename a column using the following syntax:
|
|
|
|
[source,esql]
|
|
----
|
|
RENAME <old-name> AS <new-name>
|
|
----
|
|
|
|
For example:
|
|
|
|
[source,esql]
|
|
----
|
|
include::{esql-specs}/docs.csv-spec[tag=rename]
|
|
----
|
|
|
|
If a column with the new name already exists, it will be replaced by the new
|
|
column.
|
|
|
|
Multiple columns can be renamed with a single `RENAME` command:
|
|
|
|
[source,esql]
|
|
----
|
|
include::{esql-specs}/docs.csv-spec[tag=renameMultipleColumns]
|
