TaoJIn created CALCITE-5857:
-------------------------------

             Summary: set org.apache.calcite.sql.validateScopeChild  to 
protected or public
                 Key: CALCITE-5857
                 URL: https://issues.apache.org/jira/browse/CALCITE-5857
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.34.0, 1.35.0, 1.36.0
            Reporter: TaoJIn
             Fix For: 1.35.0, 1.36.0, 1.34.0


org.apache.calcite.sql.validate.ScopeChild had a package private visibility.
{code:java}
class ScopeChild {
  final int ordinal;
  final String name;
  final SqlValidatorNamespace namespace;
  final boolean nullable;
  ...
}
{code}

But it appear on a public interface 
org.apache.calcite.sql.validate.SqlValidatorScope.This make SqlValidatorScope 
could not be impelemnted or extend .
{code:java}
public interface SqlValidatorScope {
...
  Map<String, ScopeChild> findQualifyingTableNames(String columnName,
      SqlNode ctx, SqlNameMatcher nameMatcher);
...
}
{code}

So it's possible to make the class public or protected, and the 
SqlValidatorScope could be used.
