["Shuyi Chen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CALCITE-2161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16346222#comment-16346222 ] 

Shuyi Chen commented on CALCITE-2161:
-------------------------------------

I am thinking of add the following method to the Schema interface. Can you shed some light on the changes needed, [~julianhyde]?

 

 
{code:java}
public interface Schema {
......

 /**
 * Returns a type with a given name, or null if not found.
 *
 * @param name Table name
 * @return Table, or null
 */
 RelDataType getType(String name);

 /**
 * Returns the names of the types in this schema.
 *
 * @return Names of the tables in this schema
 */
 Set<String> getTypeNames();
......
}
{code}
