Result Sets

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

The query can contain any of the following:

  • Joins
  • Aggregates
  • 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:openexchangerates:AppId=abc1234;";

Connection conn = DriverManager.getConnection(connectionString);
PreparedStatement pstmt = conn.prepareStatement("SELECT Id, Statistics_ViewCount AS My_Statistics_ViewCount, GETDATE() FROM Projects WHERE Id = 'MyId'");
pstmt.executeQuery();
ResultSetMetaData rs = pstmt.getMetaData();
for(int i=1;i<=rs.getColumnCount();i++) {
  System.out.println(rs.getColumnName(i));
}
