[jira] [Created] (SPARK-30392) Documentation for the date_trunc function is incorrect

Ashley created SPARK-30392:
------------------------------

             Summary: 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


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');
