Volodymyr Vysotskyi commented on CALCITE-2507:
----------------------------------------------

This PR does not handle a case when column name is fully specified (including 
schema and table names) with several levels of schema nesting.

Calcite allows such queries, for example, the next test put into 
{{SqlValidatorTest.java}} passes
{code:java}
  @Test
  public void testFullyQualified() {
    sql("select catalog.sales.nest.emp_r.* from catalog.sales.nest.emp_r")
      .ok();
  }
{code}

> Aliasing a star in select list should throw a parsing error.

> 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}
