public String[] getColumnNames()
Returns the names of the columns in the result. The order of the names in the array 
matches the order in which columns are returned in method getRowsByIndex().

 public int getRowCount()
Returns the number of rows in the cached ResultSet

 public SortedMap[] getRows()
Returns the result of the query as an array of SortedMap objects. 
Each item of the array represents a specific row in the query result.

A row is structured as a SortedMap object where the key is the column name, 
and where the value is the value associated with the column identified by 
the key. The column value is an Object of the Java type corresponding 
to the mapping between column types and Java types defined by the JDBC 
specification when the ResultSet.getObject() method is used.

The SortedMap must use the Comparator 
java.util.String.CASE_INSENSITIVE_ORDER. 
This makes it possible to access the key as a case insensitive representation 
of a column name. This method will therefore work regardless of the case of 
the column name returned by the database.

 public Object[][] getRowsByIndex()
Returns the result of the query as an array of arrays. 
The first array dimension represents a specific row in the query result. 
The array elements for each row are Object instances of the Java type 
corresponding to the mapping between column types and Java types defined 
by the JDBC specification when the ResultSet.getObject() method is used.

 public boolean isLimitedByMaxRows()
Returns true if the query was limited by a maximum row setting
