Databricks Dialect, Count() Validation

[harryaultdev]

Quick issue or me being stupid.

Using the Databricks Dialect I get a parse failure with count() when it involves multiple columns, it’s returning a validation error stating count can only accept one argument.

In SparkSQL Count(a.Id,a.test) is perfectly valid though.

can you show the documentation where this is legal?

Yeah sure you can find it here! Not painfully obvious and a a bit of a niche usecase. Would just return a count where all the expressions / columns are not null. Think it might be Databricks specific.
