Rename

serverless: ga
stack: ga

The RENAME processing command renames one or more columns.

Syntax

RENAME old_name1 AS new_name1[, ..., old_nameN AS new_nameN]

The following syntax is also supported {applies_to}stack: ga 9.1:

RENAME new_name1 = old_name1[, ..., new_nameN = old_nameN]

::::{tip} Both syntax options can be used interchangeably but we recommend sticking to one for consistency and readability. ::::

Parameters

old_nameX : The name of a column you want to rename.

new_nameX : The new name of the column. If it conflicts with an existing column name, the existing column is dropped. If multiple columns are renamed to the same name, all but the rightmost column with the same new name are dropped.

Description

The RENAME processing command renames one or more columns. If a column with the new name already exists, it will be replaced by the new column.

A RENAME with multiple column renames is equivalent to multiple sequential RENAME commands.

Examples

Rename a single column

:::{include} ../examples/docs.csv-spec/rename.md :::

Rename multiple columns in one command

:::{include} ../examples/docs.csv-spec/renameMultipleColumns.md :::

The same result can be achieved with multiple RENAME commands:
