[jira] [Created] (CALCITE-1551) RelBuilder's project() doesn't preserve alias

Jess Balint created CALCITE-1551:
------------------------------------

             Summary: RelBuilder's project() doesn't preserve alias
                 Key: CALCITE-1551
                 URL: https://issues.apache.org/jira/browse/CALCITE-1551
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Jess Balint
            Assignee: Julian Hyde
            Priority: Minor


The alias should be preserved by the project node, e.g.
{code:java}
.scan("EMP")
.as("EMP_alias")
.project(...) // resets alias to null
.project(builder.field("EMP_alias", "DEPTNO")) // fails that no such alias exists
{code}
