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:sugarcrm:InitiateOAuth=GETANDREFRESH;URL=http://mySugarCRM.com;User=myUser;Password=myPassword;";

Connection conn = DriverManager.getConnection(connectionString);
PreparedStatement pstmt = conn.prepareStatement("SELECT Name, Industry AS My_Industry, GETDATE() FROM Accounts WHERE Industry = 'Manufacturing'");
pstmt.executeQuery();
ResultSetMetaData rs = pstmt.getMetaData();
for(int i=1;i<=rs.getColumnCount();i++) {
  System.out.println(rs.getColumnName(i));
}
