Ashley updated SPARK-30392:
---------------------------
Attachment: Date_trunc.PNG
> Documentation for the date_trunc function is incorrect
> ------------------------------------------------------
>
> Key: SPARK-30392
> URL: https://issues.apache.org/jira/browse/SPARK-30392
> Project: Spark
> Issue Type: Documentation
> Components: SQL
> Affects Versions: 2.4.3
> Reporter: Ashley
> Priority: Minor
> Attachments: Date_trunc.PNG
>
>
> The documentation for the date_trunc function includes a few sample SELECT
> statements to show how the function works:
> [https://spark.apache.org/docs/2.3.0/api/sql/#date_trunc]
> In the sample SELECT statements, the inputs to the function are swapped:
> *The docs show:* SELECT date_trunc('2015-03-05T09:32:05.359', 'YEAR');
> *The docs _should_ show:* SELECT date_trunc('YEAR',
> '2015-03-05T09:32:05.359');
