Result Sets

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:sql:user=myuser;password=mypassword;Server=localhost;Database=Northwind;";

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