> Key: SPARK-19928
> URL: https://issues.apache.org/jira/browse/SPARK-19928

> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Jacek Laskowski
> Priority: Minor

> Despite `grouping` being used with no {{GroupingSets/Cube/Rollup}} the message is plain wrong as the number of arguments for the function is indeed correct (but failed type checking).

> scala> sql("select grouping(*) from t1").show
> org.apache.spark.sql.AnalysisException: Invalid number of arguments for function grouping; line 1 pos 7
