Julian Hyde created CALCITE-546:
-----------------------------------
Summary: Allow table, column and field called "*"
Key: CALCITE-546
URL: https://issues.apache.org/jira/browse/CALCITE-546
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Currently if we see an asterisk in an identifier, we translate it to an
identifier name segment called "*". If there happens to be a table, column or
field called "*" we're sunk.
Star can only validly occur in the SELECT clause (not in FROM or WHERE).
Examples: {{select emp.* from emp}}, {{select x from sales.*}}, {{select 1 from
emp where emp.* is not null}}.
This task is to test with tables, columns, fields called "*", and use a special
value in SqlIdentifier. Maybe the empty string would work. Names cannot be
empty.
