> Currently aliasing a Star column is not throwing an exception in parser. There is a TODO for a simple test case (in SqlParserTest.java) to throw an error in parser phase itself. 
> Change the parser grammar so as to report an error in parsing phase itself. 
> {code:java}
> // TODO: should fail in parser
> @Test public void testStarAsFails() {
> sql("select * as x from emp")
> .ok("SELECT * AS `X`\n"
> + "FROM `EMP`");
> }
> {code}
