Class IQRelationalResultSetMetaData

com.sas.iquery.execution2.IQRelationalResultSetMetaData

All Implemented Interfaces:

IQResultSetMetaData

public class IQRelationalResultSetMetaData

IQRelationalResultSetMetadata is a relational implementation of IQResultSetMetaData. Being an IQResultSetMetaData, we provide the ability to retrieve the data items that were used to create the underlying result set.

At this time, no relational result sets provide the ability to drill, but future relational subclasses of IQResultSetMetadata could be added.

For example, a future relational class could be added with this inheritance:

 
 public class IQRelationalDrillableResultSetMetaData extends AbstractIQResultSetMetaData;
 
 public List getDrillPaths(int axis) throws ExecutionException {
    // relational implementation provided here to override
    // default implementation in abstract class
 }
 

Constructor Summary

IQRelationalResultSetMetaData(java.sql.ResultSet resultSet)
Create an IQRelationalResultSetMetadata object, based on metadata derived from the underlying, concrete, java.sql.ResultSet object and information provided by the IQ model.

IQRelationalResultSetMetaData(java.sql.ResultSet resultSet, BusinessQuery bq)
Create an IQRelationalResultSetMetadata object, based on metadata derived from the underlying, concrete, java.sql.ResultSet object and information provided by the IQ model through the input BusinessQuery.

Method Summary

java.sql.ResultSet

getResultSet() Returns the underlying, concrete, java.sql.ResultSet object.
