[jira] [Created] (SPARK-29821) Allow calling non-aggregate SQL functions with column name

Max Härtwig created SPARK-29821:
-----------------------------------

             Summary: Allow calling non-aggregate SQL functions with column name
                 Key: SPARK-29821
                 URL: https://issues.apache.org/jira/browse/SPARK-29821
             Project: Spark
          Issue Type: Improvement
          Components: Java API
    Affects Versions: 2.4.4
            Reporter: Max Härtwig


Some functions in sql/functions.scala can be called with a Column or String parameter, other can only be called with a Column parameter. This behavior should be made consistent.

 

Example:

Exists:{{ sqrt(e: Column): Column}}

Exists:{{ sqrt(columnName: String): Column}}

Exists:{{ isnan(e: Column): Column}}

Doesn't exist: {{isnan(columnName: String): Column}}
