[jira] [Created] (SPARK-19850) Support aliased expressions in function parameters

Herman van Hovell created SPARK-19850:
-----------------------------------------

             Summary: Support aliased expressions in function parameters
                 Key: SPARK-19850
                 URL: https://issues.apache.org/jira/browse/SPARK-19850
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.1.0
            Reporter: Herman van Hovell
            Assignee: Herman van Hovell


The SQL parser currently does not allow a user to pass an aliased expression as function parameter. This can be useful if we want to create a struct. For example {{select struct(a + 1 as c, b + 4 as d) from tbl_x}} would create a struct with columns {{c}} and {{d}}, instead {{col1}} and {{col2}}.
