------------------------------------
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}
