How to return a record's column head given a record of a table.

Question

Hi:
Do you know how to return a record's column head given a record of a table.
For example, in a table with 3 columns "ID", "Education", "Age".
Give you the record "Bachelor", how can you use a SQL to return the correspondent column head "Education"?
Thanks for the big help.

Have a look at http://java.sun.com/j2se/1.4.2/docs/api/java/sql/ResultSetMetaData.html.
import java.sql.*;
import java.util.*;
ResultSet rs = stmt.executeQuery("SELECT * FROM testTable");
ResultSetMetaData rsmd = rs.getMetaData();
// loop through rsmd.getColumnCount() {
     String columnName = getColumnName(i);
     // run a query SELECT * FROM testTable WHERE columnName='Bachelor'
     // if rs !=null return columnName and break out of the loop
}
