Use `RENAME` to rename a column using the following syntax:
|
|
|
|
|
|
|
|
|
|
[source,esql]
|
|
|
|

|
|
|
RENAME <old-name> AS <new-name>
|
2023-06-26 22:31:53 +08:00
|
|
|

|
|
|
|
|
|
|
|
|
|
For example:
|
2023-06-06 00:38:55 +08:00
|
|
|
|
|
|
|
|
[source,esql]
|

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:
