You can use ResultSetMetaData to retrieve metadata about the results of a query.

The query can contain any of the following:

• Aliases
• Fully qualified names
• Generated columns

You can instantiate a ResultSetMetaData object by invoking the getMetaData method of the Statement class. A ResultSetMetaData instance is populated with data after the statement has been executed. The following query prints out the columns in the result of the query:

String connectionString = "jdbc:exchange:User='[email protected]';Password='myPassword';Server='https://outlook.office365.com/EWS/Exchange.asmx';Platform='Exchange_Online';Schema='EWS';";

Connection conn = DriverManager.getConnection(connectionString);
PreparedStatement pstmt = conn.prepareStatement("SELECT LastModifiedByName, GivenName AS My_GivenName, GETDATE() FROM Contacts WHERE BusinessAddress_City = 'Raleigh'");
pstmt.executeQuery();
ResultSetMetaData rs = pstmt.getMetaData();
for(int i=1;i<=rs.getColumnCount();i++) {
  System.out.println(rs.getColumnName(i));
}
