Get metadata info while query execution

[jane_lj]

After register metadata into metadataFactory in ExecutionFactory, if I need to access metadata info, e.g. table name, column name and data type in queryexecution class, how to get them?

Code sample?

Thanks.

The pushdown query will contain the metadata objects - for example see org.teiid.language.ColumnReference implements MetadataReference<Column>, which means you can call getMetadataObject() to get the Column.  If you need metadata outside the scope of your query, then use org.teiid.metadata.RuntimeMetadata instance that is passed in when your Execution is created.  It has methods such as getTable(String) that can look up a metadata object based upon the fully qualified Teiid name.
